Boot setup

2016-10-18T11:51:15Z

Bukkit: /* In the case of a broken R button */ typos

The uBoot bootloader normally boots the OS from NAND, but it can be inhibited by pressing R while starting up to for example pick SD-card booting. This can also be set up with text-files, making it the default behaviour.

==Set up your boot.txt==

Create a new file called boot.txt (or autoboot.txt if you want to boot automatically) and copy and paste the text below. Copy that file to the root of the root of the SD card.

{{warning
|If you edit the file on Windows, use an advanced text editor like [http://notepad-plus-plus.org/ Notepad++] and be sure to convert to UNIX format (in NP++: Edit -> EOL Conversion -> UNIX format). If you have DOS linebreaks, ext2load will fail with an error like "file not found" as it appends an hidden character to the uImage file name.
}}boot.txt (from the [http://openpandora.org/firmware/README.txt official firmware site])
<source lang="bash">
setenv bootargs root=/dev/mmcblk0p1 rw rootwait vram=6272K omapfb.vram=0:3000K mmc_core.removable=0
ext2load mmc 0 0x80300000 /boot/uImage
bootm 0x80300000
</source>
Note: If you chose ext3 instead of ext2 for the partition containing the kernel, the second line still starts with ext2load. There is no ext3load.

Note: depending on firmware version kernels might be at several, sometimes multiple locations, so you have to choose one:
* /boot/uImage-3 - the default 3.2 kernel (recommended)
* /lib/boot/uImage - alternative location of 3.2 kernel on certain older firmwares
* /boot/uImage - mostly a symlink to the latest kernel on recent firmwares

Be aware though that this boot.txt assumes you have formatted your card with ext2 and loads the kernel off the SD card. It is technically possible to boot the kernel from NAND but still run the rest of the file system from your SD card with following boot.txt
<source lang="bash">
setenv bootargs root=/dev/mmcblk0p1 rw rootwait vram=6272K omapfb.vram=0:3000K mmc_core.removable=0
ubi part boot && ubifsmount boot && ubifsload ${loadaddr} uImage && bootm ${loadaddr} && boot
</source>
However this is not recommended because kernel modules on SD card will likely be not compatible with kernel on NAND.

Both boot.txt's assume you are booting from the left SD card slot, first partition. You can change "mmcblk0p1" to "mmcblk1p1" if you want to boot from the right slot (but boot.txt must still be on a card on the left slot).

===Rescue console boot===
If you have a problem booting, and need to rescue data from the [[NAND]]) you can boot into a console by doing the following: Make a file named boot.txt in root of SD with this[http://www.gp32x.com/board/index.php?/topic/54918-unbricking-my-pandora/page__view__findpost__p__885362]:
<pre>
setenv bootargs ubi.mtd=4 ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs rw rootflags=bulk_read console=tty0 vram=6272K omapfb.vram=0:3000K init=/bin/bash
ubi part boot && ubifsmount boot && ubifsload 0x80300000 uImage && bootm 0x80300000 && boot
</pre>
then hold down the right shoulder button on boot and booting from the SD card. (It doesn't require an operating system on the SD card, but it will use the boot configuration specified there). This is a text mode boot to the shell, using the kernel from the [[NAND]].
This should provide a way of bypassing any broken startup scripts, adding in logging for a normal boot, etc. It does not start the full OS, just a basic shell.

===Setting up multiple-partition SD cards for booting===

It is possible to have several partitions on the SD card and boot from one of them.
E.g. if you have three partitions on the card like this:
*Partition 1: FAT
*Partition 2: ext2 (where the rootfs should be placed)
*Partition 3: swap

How it's done:

1. Put uBoot's boot control files "boot.txt" and/or "autoboot.txt" into the root of the '''first partition''' of the card (FAT partition in this example)

2. Make "boot.txt" and "autoboot.txt" point U-Boot to the '''partition, which holds the root file system''' of your Linux system. This would be parition 2 in this example (ext2 FS).
This is done '''using the "root" parameter of setenv'''.

3. Make "boot.txt" and "autoboot.txt" point U-Boot to the correct '''location to boot your kernel from'''.
This kernel location can be any FAT or ext2/3/4 partition on the SD card.
The uBoot commands '''"fatload" and "ext2load" with their parameter "mmc x:y"''' are repsonsible for loading the kernel. Choose the command, which addresses the file system the kernel is located on and make sure to correctly adapt the values x and y.

This common example boots the kernel from the FAT partition (then this is a "boot partition"), and uses the ext2 file system as root FS:

<source lang="bash">
setenv bootargs root=/dev/mmcblk0p2 rw rootwait vram=6272K omapfb.vram=0:3000K mmc_core.removable=0
fatload mmc 0:1 0x80300000 uimage
bootm 0x80300000
</source>

If you put the kernel into the root file system's /boot directory, the second line would be different:

<source lang="bash">
setenv bootargs root=/dev/mmcblk0p2 rw rootwait vram=6272K omapfb.vram=0:3000K mmc_core.removable=0
ext2load mmc 0:2 0x80300000 /boot/uImage
bootm 0x80300000
</source>

'''Note: '''

For both the "root=" kernel argument and the "mmc x:y" argument of the fatload/ext2load commands, slot numbering begins at 0 (0 is left SD slot, 1 is right SD slot) and partition numbering begins at 1!

'''Recommendation:'''

Put the kernel into another partition than the root FS is located.
Reason: In case the root FS partition is flagged "inconsistent" after a system crash or sudden SD card removal, uBoot won't be able to boot from that partition anymore. But the file system cleanup routines can only be run, once the kernel has been booted. Hence it's safer to put the kernel on a different partition.

If you want to use ext4 for the root FS, it is necessary to put the kernel on a different partition.

==Boot the system==

As you power up the Pandora, hold the shoulder button R. A menu should appear, allowing you to boot from the SD card. (this step isn't necessary if you chose to create an autoboot.txt instead of boot.txt). Remember that this will be an un-configured image, taking a little while longer to boot, and giving the first-run dialogue.

==Access the NAND==
Once you're booted into the system from SD, you may want access to the NAND rootfs. The following will let you do that.
<source lang="bash">
sudo mkdir /mnt/nand
sudo ubiattach /dev/ubi_ctrl -m 4
sudo mount -t ubifs ubi0:rootfs /mnt/nand
</source>

==Extending intall environment==
An alternative approach to using an SD card to increase the space accessible to the system is [[Extend_Utils#OS_Extends | OS Extend]]. This allows the root filesystem to exist on more than one physical device.

==References==
*[http://openpandora.org/firmware/ Official firmware page]
*[http://repo.openpandora.org/?page=detail&app=sd-install-2011-03-10 The GUI-driven SD installer by David Boucher]

=Copy the files to your SD card=
Navigate (cd) to the directory with the .tar.bz2 file you just downloaded (or made) and do:

<source lang="bash">
sudo tar -xvjf <tarfile>.tar.bz2 -C <SD card>
</source>

If you're doing this on your Pandora, <SD card> is something like /media/mmcblk0p1 (first SD card slot on Pandora). On Ubuntu it would be something like /media/disk if it has no label. You can also try using GUI tools for this, but I didn't have very good luck with them.

===OR copy your firmware from the NAND to the SD card===

The following will ask for your password. All the operations need root permissions so I thought it would be wasteful to sprinkle sudo to everything.
We will bind mount the root fs to an alternative location ("/mp"), under which other filesystems mounted under root (like the kernel virtual filesystems /proc and /sys, and your SD card.) wont be visible. This allows us to take a live copy of the NAND contents to the SD filesystem.

<source lang="bash">
sudo su
mkdir /mp
mount --bind / /mp
cp -va /mp/* /media/<SD card>
umount /mp
rmdir /mp
exit
</source>

== serial port ==
In an unlikely event that you can get serial output from EXT port, be aware that serial device has changed several times (due to the driver and port configuration changes in the kernel):
* openpandora.org 2.6.27: ttyS0
* mainline upto 2.6.36: ttyS2
* mainline/openpandora.org 2.6.37 and up: ttyO2
This is relevant for console= bootarg.

== MLO bootloader ==
Holding START while switching it on will only work if you have a bootable SD Card with a special MLO bootloader in the left SD slot, as this forces the Pandora to boot from SD.

== In the case of a broken R button ==
The file that kicks things off is boot.scr.
Place an autoboot.txt file on the SD card to trigger an automatic boot off the SD card without having to use the right shoulder button.
Create autoboot.txt file that would load the boot.scr file and start the reflash :
setenv bootcmd ’mmc init;fatload mmc 0 0x82000000 boot.scr; source 0x82000000’

* To do so, go to PayPal, log in and click on "Send Money". Donate to donation@openpandora.org and indicate in the PayPal comment field that you are donating for the Slackware project. Then PM me, so I will include you in my thx list ;^).

= Older releases Wiki pages =
* To keep this front page clean for the most recent release - 14.1 -, I moved previous versions elsewhere.
* The old page for the 14.0 release is located [http://pandorawiki.org/Software_projects/OS/Slackware-14.0 here.]
* The old page for the 13.37 release is located [http://pandorawiki.org/Software_projects/OS/Slackware-13.37 here.]

= OS architecture =
* ARMv5te, little endian, software float ("soft-float", "armel"), EABI.

= Stable or -current ? =
* Stable is for production use, ie. for work, as a server etc..
* -current is a work in progress. Although it's pretty usable, some things may be broken/unstable.
* I won't rebuild the OS if there's no big bad bug, I'll just add important features as packages. Of course, official Slackware updates are included.
* -current rootfs may be smaller or bigger from build to build, as I can include or remove KDE, amongst other things.
* If you want to help the development, I prefer that you use -current.
* And finally, -current repository may be empty. It's because a new stable release is out.

= A word about SOLEIL =
* [http://pandorawiki.org/SOLEIL SOLEIL] is another project of mine, based on SL4P.
* It's basically the same OS from the Pandora point of view, but has some neat extended features. Feel free to take a look at it.

= Media choice =
* SL4P runs on a SD card. It fits well on 8G, but 16G or more are recommended if you plan to install all the pre-compiled packages.
* The SD card must support Linux filesystems, see [http://pandorawiki.org/SD_compatibility_list this SD compatibility chart].
* I myself recommend the [http://www.sandisk.com/products/memory-cards/sd/ SanDisk Extreme, Extreme PLUS, or Extreme Pro cards].

= Installation =
Note: if you're a Linux noob, and you're scared by this Wiki page, check [http://boards.openpandora.org/index.php?/topic/11132-tutorial-format-your-sd-card-and-install-slackware-using-only-your-pandora/#entry206993 this simple tutorial] from F_Slim. Thanks to him.<br>
Note: if you are one of the last windows users, you can install SL4P using the method nicely provided by ingoreis. Check [http://boards.openpandora.org/index.php?/topic/10548-slackware14rc3-for-pandora-pretty-easy-install-for-windows-users/ this thread.]
* Format a 8G or more SD card with the Ext2 filesystem. To make explanations clear, name it SLACK.
* If you don't know how to format a drive, use GParted under Linux, or run their [http://sourceforge.net/projects/gparted/files/latest/download?source=files Live-CD]. Here's the [http://gparted.sourceforge.net/display-doc.php?name=help-manual manual].
* It's highly recommended to have a second partition formated as a swap. 256M or more is a good choice. 512M is wiser is you plan to compile some stuff, or for server use.
* If you don't plan to use this partition configuration (OS followed by swap), you'll have to edit the [http://www.tuxfiles.org/linuxhelp/fstab.html /etc/fstab] after having uncompressed the rootfs.
* If you're cleaning up a previous SL4P installation for a fresh new one, proceed like this:
rm -rf /media/SLACK/*
rm -rf /media/SLACK/.cache/
rm -rf /media/SLACK/.keepdir/
rm -rf /media/SLACK/.splash/
rm -rf /media/SLACK/.subversion/
rm -rf /media/SLACK/.Trash-0/
then unmount, fsck and sync before plugging back the card.
* To do this, get the SD device name:
cat /proc/mounts
You will see something like:
/dev/sdc1 /media/SLACK ext2
* Unmount the partition:
umount /media/SLACK/
then check the partition with fsck
fsck -y /dev/sdc1
and sync:
sync
* Grab the latest 14.1 rootfs [http://slackware.openpandora.org/pandora/index.php?dir=sl4p%2Fsl4p-14.1%2Frootfs here.]
Or
* Grab the latest -current (unstable) rootfs [http://slackware.openpandora.org/pandora/index.php?dir=sl4p%2Fsl4p-current%2Frootfs here.] The -current repository may be empty. It's because a new stable release is out.
* Plug back the SD card to remount it.
* Uncompress the rootfs on your SD. Be root, using su -, or sudo:
sudo tar jxvfp SL4P-[version]-[build].tar.bz2 -C /media/SLACK/ --numeric-owner

= First run =
* Be sure your Pandora's clock is set. Otherwise, your filesystem will be checked.
* Power down your Pandora, insert the SD card in the left slot (also called slot 1), and power on your unit.
* If you're prompted to enter the root password for maintenance or to type Ctrl-D, just wait, the unit will restart and check the filesystem automatically.
* You will be prompted to choose a password for the root user.
* You will be prompted to create an user. At some explicit point, push [up] to put this user in adequate groups.
* Then you'll be driven to the log in screen. <span style="color:#FF0000">Do not log in as the root user</span>
Bug: very unlikely to happen, but when using startx (not the SL4P default setup), you can be blocked at a black screen.
Use pandora button + power to reboot.

= Autologin =
* The GDM login manager, which is SL4P's default, can automatically log in an user. You're asked about it at the first login. Else, use
gksu /usr/sbin/gdmsetup
to change the configuration.
* KDM works, but is too heavy. You have to edit /etc/rc.d/rc.4 in order to use it.
* Slim works, but now leads to unexpected results when using gksu, therefore was replaced by GDM for the 14.1 release.

= Basic usage =
* In order to type commands as root, you have to type su -. You can use just su, but I don't recommend it because you won't have the full root environment.
* When using adduser, at some explicit point, push [up] to put this user in adequate groups.
* To choose a window manager, type xwmconfig.
* I ship those:
Xfce
fluxbox
blackbox
WindowMaker
twm
9wm
enlightenment17
jwm
minimenu
openbox
wmii
* In some -current or -RC builds, i ship KDE. Avoid selecting it as full desktop on 256M Pandora.
* To power off, or reboot your Pandora when not in Xfce and it's user-friendly menus, become root with:
su -
and type:
halt
or
reboot

= Setting up your language =
* You can set your locale pretty easily. First, you have to know which languages are available, type:
locale -a
* Choose the one that best suits your need. I highly recommend to use the versions with .utf8 .
* Then be root and edit /etc/profile.d/lang.sh .
su -
emacs /etc/profile.d/lang.sh
* You'll have to change this variable with the one you need:
export LANG=<span style="color:#FF0000">en_US.UTF-8</span>
* Save the file, make sure it's executable:
chmod +x /etc/profile.d/lang.sh
* Reboot.

= Services started at boot =
* To enable or disable services at boot, become root, then type pkgtool, then go in setup -> services, check the option with space then push enter.
* Some services are not listed here. For example, to activate the NFS server permanently, tweak /etc/exports and /etc/hosts.allow, then:
chmod +x /etc/rc.d/rc.nfsd
/etc/rc.d/rc.nfsd start (not needed after a reboot)

= Installing a program - Tools =
* Slackware archives are .tgz or .txz .
* Slackware uses three powerful tools: installpkg, removepkg and upgradepkg.
* A fourth tool named makepkg build packages from compiled sources.

= Installing a program from source =
* The cleanest way to do it is to use a SlackBuild script: http://slackbuilds.org/guidelines/
* Many SlackBuilds for Slackware 14.1 are already available here: http://slackbuilds.org/repository/14.1/
* I shipped a tool named sbopkg, which does the job for you. Become root using su - , then sync it with the internet repository with:
sbopkg -r
* The sync may take some time. Once you've done that, run
sh /root/sboflags.sh
to optimize the builds for the Pandora. You have to run this script after every sync.
* Then all is set up, you just have to use
sbopkg
and choose "Local SlackBuild" when prompted.
* When the job is done, remove useless files to save disk space:
rm -rf /tmp/SBo/*
rm -rf /var/cache/sbopkg/*
* Note that Slackware does not check dependencies, so you have to get the right build orders looking here: http://slackbuilds.org/
* To check if some of the dependencies are already installed in your system, look in /var/log/packages/ . For example, libgnomecanvas:
ls /var/log/packages/libgnomecanvas*
* Also note that gnome libraries must be compiled in a certain order. I already did the job, and shipped them in the rootfs.
* If you don't use a SlackBuild script, then the Slackware procedure almost always ends like:
make install DESTDIR=/tmp/whatever/
cd /tmp/whatever/
makepkg /tmp/whatever-1.0.0-arm-1.tgz
installpkg /tmp/whatever-1.0.0-arm-1.tgz

= Installing a program with a precompiled archive =
* I compiled a lot (450+) of packages from http://slackbuilds.org/.
* I shipped a graphical install tool named GSlapt. Launch it with its icon, update the package list, then install what you need, checking the dependencies of your programs here: http://slackbuilds.org/
* You can also proceed manually. Find 14.1 packages [http://slackware.openpandora.org/pandora/index.php?dir=sl4p%2Fsl4p-14.1%2Fpackages%2Fextra here], and -current ones [http://slackware.openpandora.org/pandora/index.php?dir=sl4p%2Fsl4p-current%2Fpackages%2Fextra here.]
* Download what you need, checking the dependencies of your programs here: http://slackbuilds.org/
* Put all needed .tgz or .txz in a folder, go root using su -, then type:
installpkg /path/to/your/folder/*.t?z
* Please report any non-working package.

= About SL4P precompiled archives =
* All shipped and extra archives are compiled with sbopkg with Pandora-optimized flags.
-DPANDORA -O2 -pipe -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -fPIC
* The links to the sources are located here: http://slackbuilds.org/repository/
* The building order is fixed in queue files, kind of build playlist.
* The queues are located in /var/lib/sbopkg/queues/
* About [http://slackware.openpandora.org/pandora/index.php?dir=sl4p%2Fsl4p-14.1%2Fpackages shipped] archives (base and base-more), you don't need to download them as they're already in the rootfs, see [http://pandorawiki.org/Software_projects/OS/Slackware/Build-system this.]
* Some archives won't work, like Kompozer, because it's a repackaging of x86 binaries. As I'm not yet in the process of fine-tuning, I left them for now.

= Installing KDE 4 =
* Plug the net, become root using su -, then type:
slackpkg update
slackpkg install kde
* Note that although i already slimmed down KDE configuration files for less eye-candy, a 512M Pandora is recommended to run the full desktop.
* Anyway, you can run any KDE application (konqueror, kwrite...) flawlessly with the 256M version.
* Type xwmconfig to select KDE, or any other window manager.

= Updates =
* You may eventually read [ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-14.1/ChangeLog.txt the Slackware ARM 14.1 changelog here]
* If you need an up-to-date security, you should consider subscribing to the main [http://slackware.com/lists/ Slackware mailing list]. Slackware ARM updates are generally available a bit later.
* For stable releases, plug the net, become root using su -, then type:
slackpkg update
slackpkg upgrade-all
* Do not use slackpkg when using a -current. Instead, look at the [ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-current/ChangeLog.txt changelog], download packages from [ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-current/slackware/ here], become root using su -, then type:
upgradepkg /path/to/the/updates/*.t?z
Note that some packages like a/aaa_elflibs are not supposed to be upgraded in -current. A new rootfs is needed.

* You can eventually set up a cronjob. In this case, check /etc/slackpkg/blacklist to ensure some critical packages (e.g. kernel) will not be updated.
* Slackware usually provides updates during 10+ years, but it seems to be less with Slackware ARM. See [http://www.armedslack.org/ the news for more details].

= SL4P-specific updates =
* I provide Pandora fixes, available as Slackware archives.
* Simply use GSlapt, and update.

= Firefox, Thunderbird, SeaMonkey and Java-OpenJRE/JDK updates =
* Slackware ARM 14.1 doesn't provide anymore updates for Firefox, Thunderbird and SeaMonkey because of a build problem.
* You have to download the unsupported -current archives and update them manually, using the method mentioned above.
* Get them [ftp://ftp.arm.slackware.com/slackwarearm/unsupported/slackwarearm-current/packages/ here].
* About Java-OpenJRE/JDK, it's not possible to update them through slackpkg because it was added on-the-fly to Slackware ARM.
* Check and get the updates [ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-14.1/patches/packages/ here].
* Be sure to download and update both as the jre is not included in the jdk.

= Kernel updates =
* I provide kernel updates through GSlapt.
* Many kernels are already available in the rootfs, like real time, or non-debug.
* To know which kernel is currently running, type:
uname -r
* To enable a new kernel, for example 3.2.30-szfinal or the 3.2.26-rt, do:
cd /boot
rm uImage
cp uImage-3.2.30-szfinal uImage
or:
cd /boot
rm uImage
cp uImage-3.2.26-rt uImage
And reboot.
* If lsmod reports that no modules are loaded (that means, eg., no touchscreen), then run as root:
depmod -a
And reboot again.

= Automounting a SD card or an USB drive =
* No system-wide automounter is enabled for now.
* Only Xfce and some other window managers do automount.
* As Xfce mounts devices at insertion, if you booted with a second SD card or an USB drive plugged in, you have to click on the device icon.
* If you plan to use Minimenu, you currently have to automount under Xfce, run xwmconfig, then log out to run Minimenu. This is the best method to save RAM.
* You can also launch Minimenu under Xfce. Open a terminal and type:
mmwrapper -fmmenu

= USB at boot, suspend and powersaving =
* Usually, you have to click on the Xfce "Toggle USB Host" icon whenever you need USB support.
* I disabled the USB support by default. As said Notaz, it "Uses around 3x more power when idle, fails to suspend properly.".
* If you want to enable USB host and USB networking support at boot, be root and edit /etc/rc.d/rc.local .
Near the top, change
#modprobe ehci-hcd
into:
modprobe ehci-hcd

= Fixing the endless reboot =
* Be sure your Pandora's clock is set. Boot Official Pandora OS on the NAND, and check/set time.
* Boot SL4P, when prompted to enter the root password for maintenance, do it, then type:
fsck -y /dev/mmcblk0p1
* You can do the same under Zaxxon. Note that it will be /dev/mmcblk1p1 if SL4P is on a second card.
* You will be warned if the card is still mounted, so unmount it, and proceed.

= Changing the Hostname =
* See [http://pandorawiki.org/Software_projects/OS/Slackware/Advanced_usage/Hostname this.]

= Switching from 1GHz to 600MHz Pandora =
* I slightly modified the clock script to split the parameters into two categories: 1Ghz and 600MHz.
* You can safely put SL4P in any OP, and have a max OPP + max MHz settings for each as the model is recognized at boot, then clocked.
* It's totally transparent, just set your parameters as usual.

= Fast boot tweak =
* I moved some of the boot stuff (ldconfig, font cache, mime database) in /etc/rc.d/rc.local_shutdown.
* The reboot/power off process is slowered, but the OS integrity is safe.

= SGX drivers installer =
* With notaz's blessing, i tweaked his SGX drivers installer to make it work both under SL4P and Zaxxon.
* Get it [http://slackware.openpandora.org/pandora/index.php?dir=sl4p%2Ftools%2Fsgx_drivers_installer here.]
* You can safely remove your old version.

= PND compatibility list =
* SL4P supports .pnd files.
* PNDs used to be recognized automatically. It's not the case anymore, and I don't know why.
* So here's the workaround: after the insertion of your SD or USB drive, you have to push the [http://boards.openpandora.org/index.php?app=core&module=attach&section=attach&attach_rel_module=post&attach_id=4449 green button] near the Xfce menu.
* Due to 3.2 kernel and dynamically linked libraries, not all .pnd are compatible.
* [[Software_projects/OS/Slackware/PND-compatibility-list|View the PND compatibility list here.]]

= Advanced usage =
* I wrote some tutorials to do interesting things.
* All those guides are applicable to any version of Slackware, ie. x86, x86_64, IBM mainframe, etc.
* Follow this [http://pandorawiki.org/Software_projects/OS/Slackware/Advanced_usage link.]

= Sources =

* See the [[{{PAGENAME}}#Build system|build system]], below.

= Build system =
* I distribute it under the GPL 3 license.
* It may look a bit messy for now (and indeed, some part have to be cleaned), but it's versatile, as I intended from the start.
* It's mainly three bash scripts.
* You need a Pandora to run the third one.
* Depending on what you comment/uncomment, you can produce an alpha build, very minimal, or a full build.
* Depending on what you edit, you can use it to port any *NIX to Open Pandora, and maintain your build very easily.
* Get it [http://pandorawiki.org/Software_projects/OS/Slackware/Build-system here], along the more detailed instructions.

= FAQ =
* Available [http://pandorawiki.org/Software_projects/OS/Slackware/Slackware_FAQ here.]

= Ask a question/Report a bug =
* You're welcome to do so, and please post [http://boards.openpandora.org/index.php?/topic/1524-slackware-inside-pandora/ here] or [http://boards.openpandora.org/index.php?/topic/9797-slackware-for-pandora-140/ here.]

SD compatibility list

2012-08-31T17:19:59Z

Bukkit:

This is a compatibility list for SD, SDHC and SDXC cards. The cards listed in '''green''' work with any file system. The cards listed in '''yellow''' work well only with one file system (this still means they can be used on the Pandora). The cards listed in '''red''' do not work well with any file system. Although it is not covered on this list, the Pandora can also read NTFS-formatted SD cards if the [http://www.open-pandora.org/downloads/CodecPack.pnd Community Codec Pack] is installed.

Note: always measure read speed by opening a terminal window and typing this command:
* the first inserted SD Card: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* the second inserted SD Card: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

Note: The first inserted SD Card will always be /dev/mmcblk0, regardless if you put it into the second or first SD Card slot, whereas the second will be /dev/mmcblk1

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.
* the first inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100'''
* the second inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''

By default, the first partition starts at block 8192 (4096KB) for 32GB cards, and block 32768 (16384KB) for 64GB cards. 64GB cards may need to be [[formatting SD cards|reformatted]] before use.

SD compatibility list

2012-08-31T16:00:35Z

Bukkit: Pansonic 8

This is a compatibility list for SD, SDHC and SDXC cards. The cards listed in '''green''' work with any file system. The cards listed in '''yellow''' work well only with one file system (this still means they can be used on the Pandora). The cards listed in '''red''' do not work well with any file system. Although it is not covered on this list, the Pandora can also read NTFS-formatted SD cards if the [http://www.open-pandora.org/downloads/CodecPack.pnd Community Codec Pack] is installed.

Note: always measure read speed by opening a terminal window and typing this command:
* the first inserted SD Card: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* the second inserted SD Card: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

Note: The first inserted SD Card will always be /dev/mmcblk0, regardless if you put it into the second or first SD Card slot, whereas the second will be /dev/mmcblk1

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.

* the second inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''

By default, the first partition starts at block 8192 (4096KB) for 32GB cards, and block 32768 (16384KB) for 64GB cards. 64GB cards may need to be [[formatting SD cards|reformatted]] before use.

I let F3 run over it, the speed was measured using it too. --A few weeks later-- It has got variable w/r speed, it drops after a few seconds of writing data to it.

SD compatibility list

2012-08-31T15:52:50Z

Bukkit:

This is a compatibility list for SD, SDHC and SDXC cards. The cards listed in '''green''' work with any file system. The cards listed in '''yellow''' work well only with one file system (this still means they can be used on the Pandora). The cards listed in '''red''' do not work well with any file system. Although it is not covered on this list, the Pandora can also read NTFS-formatted SD cards if the [http://www.open-pandora.org/downloads/CodecPack.pnd Community Codec Pack] is installed.

Note: always measure read speed by opening a terminal window and typing this command:
* the first inserted SD Card: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* the second inserted SD Card: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

Note: The first inserted SD Card will always be /dev/mmcblk0, regardless if you put it into the second or first SD Card slot, whereas the second will be /dev/mmcblk1

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.
* the first inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100'''
* the second inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''

By default, the first partition starts at block 8192 (4096KB) for 32GB cards, and block 32768 (16384KB) for 64GB cards. 64GB cards may need to be [[formatting SD cards|reformatted]] before use.

I let F3 run over it, the speed was measured using it too. --A few weeks later-- It has got variable w/r speed, it drops after a few seconds of writing data to it.

SD compatibility list

2012-08-31T14:58:38Z

Bukkit: toshi 32

This is a compatibility list for SD, SDHC and SDXC cards. The cards listed in '''green''' work with any file system. The cards listed in '''yellow''' work well only with one file system (this still means they can be used on the Pandora). The cards listed in '''red''' do not work well with any file system. Although it is not covered on this list, the Pandora can also read NTFS-formatted SD cards if the [http://www.open-pandora.org/downloads/CodecPack.pnd Community Codec Pack] is installed.

Note: always measure read speed by opening a terminal window and typing this command:
* the first inserted SD Card: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* the second inserted SD Card: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

Note: The first inserted SD Card will always be /dev/mmcblk0, regardless if you put it into the second or first SD Card slot, whereas the second will be /dev/mmcblk1

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.
* the first inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100'''
* the second inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''

By default, the first partition starts at block 8192 (4096KB) for 32GB cards, and block 32768 (16384KB) for 64GB cards. 64GB cards may need to be [[formatting SD cards|reformatted]] before use.

SD compatibility list

2012-08-31T13:21:44Z

Bukkit: Toshiba 8GB

This is a compatibility list for SD, SDHC and SDXC cards. The cards listed in '''green''' work with any file system. The cards listed in '''yellow''' work well only with one file system (this still means they can be used on the Pandora). The cards listed in '''red''' do not work well with any file system. Although it is not covered on this list, the Pandora can also read NTFS-formatted SD cards if the [http://www.open-pandora.org/downloads/CodecPack.pnd Community Codec Pack] is installed.

Note: always measure read speed by opening a terminal window and typing this command:
* the first inserted SD Card: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* the second inserted SD Card: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

Note: The first inserted SD Card will always be /dev/mmcblk0, regardless if you put it into the second or first SD Card slot, whereas the second will be /dev/mmcblk1

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.
* the first inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100'''
* the second inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''

By default, the first partition starts at block 8192 (4096KB) for 32GB cards, and block 32768 (16384KB) for 64GB cards. 64GB cards may need to be [[formatting SD cards|reformatted]] before use.

I let F3 run over it, the speed was measured using it too. --A few weeks later-- It has got variable w/r speed, it drops after a few seconds of writing data to it.

SD compatibility list

2012-08-14T15:14:32Z

Bukkit: Toshiba 16Gb

This is a compatibility list for SD, SDHC and SDXC cards. The cards listed in '''green''' work with any file system. The cards listed in '''yellow''' work well only with one file system (this still means they can be used on the Pandora). The cards listed in '''red''' do not work well with any file system. Although it is not covered on this list, the Pandora can also read NTFS-formatted SD cards if the [http://www.open-pandora.org/downloads/CodecPack.pnd Community Codec Pack] is installed.

Note: always measure read speed by opening a terminal window and typing this command:
* the first inserted SD Card: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* the second inserted SD Card: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

Note: The first inserted SD Card will always be /dev/mmcblk0, regardless if you put it into the second or first SD Card slot, whereas the second will be /dev/mmcblk1

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.
* the first inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100'''
* the second inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''

By default, the first partition starts at block 8192 (4096KB) for 32GB cards, and block 32768 (16384KB) for 64GB cards. 64GB cards may need to be [[formatting SD cards|reformatted]] before use.

| Works nice. {{HideableNotes|Installed Angstrom on it and copied some stuff onto it. Angstrom runs as fast as from NAND. Best thing was, where I ordered it it said class 6, but it is actually 10. :-D Still have to test its speed and actual size. Didn't test Fat a lot, but it seemed to work.}}

----
<div style="background: #F3F781">Serious issues. {{HideableNotes|My Linux computer can't read it, but that is probably the computer. First formatted it to ext2 while leaving 16MiB free at the beginning because it was like that when I got it. Had 16MB/s r/w. Then started to have problems after writing about 64GB to it, couldn't mount it, reformatted it, no change, reformatted it as Fat32, still no change, reformatted again as fat32, no problems so far but write speed is 0.5MB/s and read speed 14.76MB/s. I let F3 run over it, the speed was measured using it too. --A few weeks later-- It has got variable w/r speed, it drops after a few seconds of writing data to it. Sometimes it gives other errors, stops working until I reboot, etc. It's useable, but I wouldn't buy it again.}}</div>
