Ångström

Super Zaxxon is currently the official operating system for the pandora based on Ångström Linux|Gnu. Super Zaxxon is a version upgrade system with frequent system-wide small releases. Compatibility is ensured as a basis of Super Zaxxon. Packages, often relying on their own environment are self retained within the .pnd format and available on a pnd repo separate from the self hosted system packages. An evolutionary non-compatible similarly customized Ångström build called .next is in development.

Installation prerequisites (Offline)

You need a pandora, and alternatively an SD card, the latter is preferred because running from SD card is the recommended install method.

General Notes

• Remember that your Pandora will turn on as soon as a charger is connected. It's also not possible to completely power down a Pandora that's connected to an external power supply.
• Even while charging, a Pandora can be rebooted, either by software (for example, during the installation process below), or with the reboot hotkey: Hold the Pandora button on the keyboard, and flick the power switch to the right.
• Do not connect an external power supply while the battery is removed.

• When the firmware is (re-)installed, all personal files and settings stored on internal flash are DELETED (your PND applications and all data on your SD cards will not be touched).
  Your Pandora will revert to it's default settings and show the first boot wizard on bootup.

Full fresh installation

To SD card (external)

1. SD card formatted with the FAT32 filesystem (default on Windows). Extract the contents of the firmware .zip file to the root (top level) directory of that card.
2. Make sure your Pandora is turned off (remove the battery in case it crashes or doesn't turn off by using normal means).

Download firmware image of Super Zaxxon 1.60 (20-dec-2013) forum thread

1. Insert the SD card into your Pandora's first slot (the one on the left, which is closer to headphone jack).
2. Press and hold the right shoulder button ('R'), then turn the power on (if you removed the battery, insert it while holding 'R').
3. A text menu should appear on screen. Switch to "boot from SD1" using the d-pad, and select this entry with either the 'B' or 'X' controller button.
4. Wait for the flash process to finish. Connect a charger to be sure the battery doesn't run out while flashing. Press enter when asked to do so. Might take up to 15 minutes, be sure to wait for it to finish.
5. If you use an external power supply, the device will reboot. Othwerwise, it should turn off - in this case press power (without holding 'R') to turn it back on.
6. It should then start it's first boot process which might take up to 15 minutes. Be sure to wait for it to finish, otherwise firmware corruption might happen. The installation process will show some warnings, which can be safely ignored.
7. When everything is set up, you will be guided through the first boot wizard.

To NAND (internal)

Where Super Zaxxon boots from out of the box.

The UBIFS-Version can be used to flash the firmware to the Pandora.

Please only use it if you really need to. Reflashing CAN solve some problems, but it's not the magical tool that can fix everything. You should always try to find another solution. Before reflashing, try the upgrade path below You can get help at the Support Section at the boards.

http://openpandora.org/firmware/images/Angstrom-pandora-xfce-image-nowifi-glibc-ipk-2010.4-test-20131220-omap3-pandora.ubifs.img

Partial distribution upgrade

Versions after Super Zaxxon 1.52 come with an online firmware update utility: Just select System -> Upgrade Pandora OS from the Pandora menu to download the latest system packages (needs working internet connection).

To SD-card

GUI-driven SD installer tool

Instead of installing the firmware manually on the SD card, you may use the GUI-driven tool sd_installer.pnd by David Boucher, which automates the entire process. http://repo.openpandora.org/?page=detail&app=sd-install-2011-03-10

You only need the downloaded firmware tarball, the sd_installer.pnd and a suitable SD card.

To NAND(internal)

You can extract the tar.bz2-version of the pandora-image onto an SD Card (EXT2) and directly boot off it.Be sure to include a kernel in /boot (unless you want to use the one on the NAND) and use a boot.txt / autoboot.txt to pass parameters to u-boot.This way, you can boot off your SD Card and meddle around with the OS without risking breaking NAND state.

Installation perquisites (Online)

It is also possible to do an install while the system is running. Grab the ubifs image and install that from nand to SD-card or vice versa. This is an advanced option.

The sourcecode for the programs included in the images can be found in the sources-directory, including licenses for each single one of them. The kernel and u-boot sourcecode as well as some other Pandora specific sourcecode can be found on http://git.openpandora.org/ Advanced users can get raw firmware images and rootfs (for SD Card bootup) as well as older versions here.

cd pandora-firmware
source ./op-env-oe.sh
./initial-setup.sh

Building Yars' Revenge W.I.P. Also called .next Query aTc or DJWillis until you get a response.

The following instructions will allow you to build the current .next image. remember that your building the tip of the expermental tree and not everything even remotely works. Best for people who want to hack and help get it into shape. Do not expect anything remotely good enough to run on your Pandora for real

It is suggested that you use debian or a debian chroot. In addidtion to the base debian install you will need autoconf automake build-essential coreutils diffstat diffstat texi2html gawk chrpath docbook-utils fdisk gawk gcc git git-core gnome-doc-utils groff help2man libc6-dev-i386 libsdl1.2-dev liburi-perl make mercurial python-pysqlite2 qemu-arm-static scrollkeeper subversion texi2html texinfo unzip util-linux x11-xserver-utils

cd <INSTALLDIR>
git clone git://github.com/openpandora/openpandora-oe-environment.git
cd openpandora-oe-environment
./openpandora-setup.sh config

This will install a number of git reposiries containing the build tools and recipes bitbake openembedded-core meta-openembedded meta-angstrom meta-texasinstruments meta-openpandora

• the basic hardware layer that works with OpenEmbedded and can be used in most OpenEmbedded distributions (Angstrom, Yocto, SHR etc.). That hardware layer also needs meta-texasinstruments (the scripts will bring that in, the Angstrom ones or ours).

meta-openpandora-vendor

• the vendor (i.e. openpandora) specific stuff, scripts, tweaks, image files, task files (i.e. what to install and order) and some recipes for things like libpnd.

From time to time you will want to update and fetch the changes to the base and openpandora recipes. e.g. those report on #openpandora by CIA-57

. ~/.oe/environment-openpandora
cd <INSTALLDIR>/openpandora-oe-environment
./openpandora-setup.sh update

There are a number of recipes for build images in openpandora-oe-environment/metadata/meta-openpandora-vendor/recipes-core/images pandora-core-image no desktop or X11 pandora-xfce-image XFCE desktop environment systemd-pndwip-image

. ~/.oe/environment-openpandora
cd <INSTALLDIR>/openpandora-oe-environment/build
bitbake systemd-core-image

This will download required sources and package dependancies, depending on the state of updatesm, build packages and produc an image.

The preferred method for sending patches for meta-openpandora and meta-openpandora-vendor is to create a fork in github apply you changes and send pull requests to OpenPandora Firmware mailing list: firmware-dev@openpandora.org Subscribe at: http://openpandora.org/cgi-bin/mailman/listinfo/firmware-dev

Kernel status

The first firmware release was based on a heavily patched linux-2.6.27-omap1 kernel. linux-omap used to be OMAP community kernel fork, nowadays its code was either merged to mainline or dropped. Further OMAP development continues on mainline kernels, linux-omap tree is mainly used to queue developed code to mainline.

Current firmware releases are based on 3.x kernel series.

Status

Driver support in 3.x series is more or less complete, however not all parts are merged to mainline kernel due to various reasons.

merged code (already in mainline as of 3.4)

• board support (enables UART, I2C, SPI, RTC, MMC{1,2,3}, NAND, OTG, EHCI, gpio-keys, leds-gpio, keypad, touchscreen, regulators)
• sound: ALSA ASoC machine driver
• bq27500 fuel gauge
• LCD panel driver
• wl1251 WiFi driver glue (portions only in 2.6.37)
• charging (partial only, 2.6.37)
• wl1251 complete powerdown/suspend using runtime_pm (2.6.38).
• backlight driver (3.4)

this doesn't list various bugfix patches to get above working :)

not merged

now in openpandora.org GIT (mainline merge status in brackets)

• nubs (aka vsense, needs rework for mainline)
• keypad fn handling (not allowed in mainline)
• PWM LEDs (needs rework)
• Overclocking support
• some charging bits (too many hacks)
• various random hacks that benefit pandora but may harm other devices, hence mainline incompatible

openpandora.org git structure

Support for various kernels is available in pandora-XX branches or tags, XX corresponds to last part of kernel version number. 2.6.27 is an exception, it's in pandora-27-omap1 branch.

Branches based on pre-release -rc kernels will be often rebased. This means you can't do 'git pull' on them, use 'git fetch; git reset --hard origin/pandora-XX' instead. Warning: this will destroy all your changes (even if they are commited), backup them first!

Configuring newer kernels

When compiling mainline kernel, use

make omap2plus_defconfig

for openpandora.org kernels you can use omap3_pandora_defconfig

make omap3_pandora_defconfig

after either of those are run, you can tune the configuration for your needs:

make menuconfig

Now you should be able to build a working kernel. More info available at Kernel build instructions.

Pandora Firmware Governance

The Pandora device is an open ecology --

The official firmware is open source and open to patches from the public; to maintain high quality firmware releases a process needs to exist -- audit trails need to be kept to ensure licensing is clear, testing has to be ensured to keep quality high, and our standard practice for submission made clear so it is easy and swift to submit your work.

Help us sort it out :) This process itself is open source -- as the ecosystem expands our model will change with it; if you are seeing problems, then contact one of the maintainers, mailing list, or the community at large and All of which are part of the Team

The firmware is all of the software that is supplied with a device, so does include the applications which are provided as standard. It is all open source (meaning that OpenPandora provides the source code, often as a requirement of the GNU GPL). A small quantity of the firmware is provided as binary files, which OpenPandora may not be at liberty to disclose the full details of. An example of closed source firmware is for the analogue nubs, which are shipped with small micro-controllers pre-programmed by the nub manufacturer. Only some of the hardware designs and occasional binary blobs like the WiFi driver are currently not open source; the rest of the firmware stack is open source (predominantly GPL with some LGPL).

Replacing the Firmware (Un-bricking)

Rather than patch the firmware, the firmware may be replaced wholesale with a freshly downloaded firmware. This ought to be regarded as a last resort in the case of problems, there is almost certainly a simpler way to fix most problems.

The process for reinstalling the firmware is as follows: [1] , otherwise firmware corruption might happen again.

In case of emergency, there is an older version here (Version: 2010-05-01-Zaxxon)

Debugging broken firmware

[2] will help you in case booting normally breaks. That way you can provide debugging info to source what went wrong instead of just re-installing.

Reporting bugs

Please do make sure that you are using the latest official firmware and hotfix. You can find it in the official support section of the website. Reports made against older versions might be invalid since the issues were already fixed.

If the bug does still exist in the latest released version, please follow these steps when reporting it in the official bug tracker. You will need to register an account in the tracker. Once you are logged into the account, just click on Add new task to see a form where you can provide the information required to assign and solve the bugs. Below is an explanation of what you should enter where.

Stuff that belongs there

• Bugs that happen with the default operating system on the pandora.
• Things missing in the default operating system on the pandora.
• Bugs and issues with the codec pack.

What does not belong in the official tracker

• Bugs with other .pnd files like eg emulators, games or other applications that are not part of the main OS.
• Features missing in other progs.

Issue attributes explained

Here is the list of things you should keep in mind and mention in your bug report or feature request to make sure that it can be solved. Please do also make sure to react on comments that are left in the report, since the people that feel responsible for solving the issues might need more information that only you can provide.

Summary

This should be a really short summary of the issue at hand, as clean as possible. Something like eg ABC does not work is not good, better write ABC crashes when sounds are played.

Drop Down Boxes

This area on the left side is used to provide some general information that makes it easier for devs to assign the reports to the correct people for fixing things. They are often useful in fixing the report in the end, too.

Task Type

Just select it from the drop down box. If you want to report a bug, make it Bug Report, if it is a missing feature, select Feature Request. You should only select To Do (Reminder) if you are one of the devs to leave a note for yourself.

Category Core

Everything that belongs to the basic systems like the kernel and the drivers. The real core that lies beneath.

Category Application

Meant for all the programs on top of the basis core. This eg. includes problems in minimenu, Pandora specific XFCE, pidgin, ... Basically you should ask yourself if your issue might be kernel/driver related, if it is not, select this one.

Status

Can only be changed by bug tracker admins (aka "official pandora devs").

Operating System

Select the "series" of the operating system on the pandora here. The first firmware series is called Zaxxon.

Severity

How important do you estimate this bug/issue? It should only be marked critical if it is a real security breach or something breaking *everything*. Often the default low is fine, since the values can be adjusted later on by bug tracker admins.

Priority

Can only be changed by bug tracker admins (aka "official pandora devs").

Reported Version

Please select which version state your pandora has in the release that you selected under Operating System. Basically list the latest hotfix that you installed.

Due in Version

Can only be changed by bug tracker admins (aka "official pandora devs").

Details

A neat, large field with lots of space for all the details that you can provide. Yes, in general a case of "the more, the better" applies here. Here is a list of things that you should mention in the report:

Problem

Detailed description of the *exact* problem you see. Please do include some log output, if you have it available.

Reproducibility

How often does the issue occur? Is it reproducible? If it is, please provide detailed steps to do so.

Actual Results

What happened after you performed the steps you listed under "Reproducibility"?

Expected Results

What should have happened?

Additional Information

Please do list any additional information, like for example the *exact* version of your OS (or the application). This is especially important if you were not able to select the exact version in the Reported Version drop down field. If you have any log output or patches, please do attach those as files to the report. If the file size would be too big, just compress them.

Syntax in the Flyspray issue tracker

Internal reference to other issues

To refer to another issue use the syntax FS#N where N is the issue number you want to refer to, i.e. FS#123. The parser then automatically renders this as a link to the other issue (HTML href attribute), and shows the issue's title in the mouseover info (HTML title attribute).

Submission Workflow

The general workflow for submitting a patch is something like this:

1. Clone the appropriate section of the GIT repository - GIT is http://git.openpandora.org/cgi-bin/gitweb.cgi
2. Apply changes and have fun
3. Document and pass test cases
4. Contact the maintainer of the subdomain the patch falls within - by mailing list above, or perhaps by PM in the forums, or email; for example, post first to the mailing list. In a pinch for libpnd submissions talk to skeezix, or notaz regarding kernel changes. But talk to the mailing list first, to keep discussion logged and centralized; if a backup neds to step up, the post history will already be there, right?
5. If the maintainer is unavailable, contact the backups as listed above; they will know how to contact the champion, or can make the submission call themselves.
6. If the maintainer and backups are not available, contact EvilDragon as release maintainer

Submission Standards

Submission are welcome! Historically the firmware has been built by a very small team, but that team size limits the number of changes that can be managed and developed simultaneously. If you've the skills and motivation to help, feel free to join the fray!

Patches have a few requirements; failing these requirements will cause your patch to be overlooked!

• Clearly documented -- what is this patch for?
• Clearly tested -- a list of test cases and test results -- the onus is on the submitter to test and prove testing; the committers have limited time and many people talking to them
• Proper format -- unix line ending, not dos line endings :)

Submitting patches

It's best to send formal GIT-generated patch so that you get proper credit for your work and to make applying the patch easier. You can also add 'Signed-off-by' line ('-s' on 'git commit' will do it for you), which has the same meaning as for mainline Linux.

So basic workflow would be:

<make changes>
git config --global user.name "My Name"
git config --global user.email "myname@domain.com"
git add <changed files>
git commit
git format-patch -o /somewhere/ -1

Then create a new feature request in bugtracker and attach the generated file(s), or send them to the mailing list, or post them on the forums, whatever is more convenient to you.

Community Codec Package - for Pandora OS, Release 2010-05

Installation of non-free codecs is highly discouraged. Consider instead free counterparts like opus, ogg vorbis and Flac for audio. webM, ogg theora for video or equivalent.

Due to licensing issues, licensed codecs like MP3 or MPEG-Video can not be distributed freely. They are optionally available in the Codec Package. The package will install Gnome-MPlayer as well as a lot of audio / video-plugins and enables NTFS-support. To install it, simply download the .PND-Package and place it into either the /pandora/menu or /pandora/desktop - Folder on your SD-Card. Simply start it and follow the on-screen instructions. You can remove the .PND-Package from the card once it has been installed.

Legal Notice

Patent and copyright laws operate differently depending on which country you are in. Please obtain legal advice if you are unsure whether a particular patent or restriction applies to a media format you wish to use in your country.

• http://boards.openpandora.org/index.php/topic/10374-superzaxxon-v152-released/
  

SuperZaxxon1.50 can be upgraded to 1.52 without reinstallation by downloading and running the Pandora SuperZaxxon updater PND.

Zaxxon (Old version) =

The original Zaxxon firmware has been updated with a number of Hotfixes. Since then, a newer firmware called Super Zaxxon has been released.

Warning: If you do not have Zaxxon installed (boot screen says SuperZaxxon or something else), do not attempt to install any of these hofixes, doing so will break the system.

In general it's possible to apply hotfixes to any lower firmware versions without installing all previous hotfixes.

Hotfix 6

• Information and discussion (2011-10-10)
• Full flash update (will delete all prior user settings; useful if you've screwed something up and are not sure of how to fix it)

Bugs and solutions

In general, the latest information about bugs will be on the official bugtracker; that is also the best place to go report a bug.

PNDs won't run

So you can start Xfce, but you can no longer run any programs or switch to Minimenu since you upgraded to HF6?

This can easily be solved without a reflash.

valhalla This problem is because of version 1.0-r58.5 of the pandora-scripts package that includes some files that it should not have included and conflicts with the new version of pandora-libpnd. That version is installed at least in HF5rc2.

1. Open a terminal in the location where you put your HF6 update PND. In the default file browser, you can do this by right-clicking in the folder where the PND is, and selecting "open terminal here". For example, if you put it on your desktop (/pandora/desktop), the text in the terminal to the left of your cursor should look something like username-openpandora:/media/pandora/mmcblk0p1/pandora/desktop$
2. Type in sudo mkdir /mnt/pnd and press "enter". If it asks you for your password, type in what you use to log in to your Pandora, then press "enter".
3. Type in sudo mount -o loop HF6-Updater.pnd /mnt/pnd and press "enter"
4. Now we'll go to the packages directory in the PND and reinstall a couple of packages. Type in cd /mnt/pnd/packages/other/ and press "enter"
5. Type in sudo opkg install pandora-libpnd_1.0-r56.5_armv7a.ipk and press "enter"
6. Type in sudo opkg install pandora-skel_1.0-r9.5_omap3-pandora.ipk and press "enter"
7. To unmount the PND, type in sudo umount /mnt/pnd and press "enter". If it says it can't unmount it, just restart your Pandora.
8. That's it, your Pandora should work again!
