MARK2

Second version
Full Debian GNU/Linux based on sid branch with LXDE desktop environment (normal) or CLI (minimal-) build.
hardfloat armv7l yule release Date: 29.12.2013 forum link

Main Features

  • The debian way.
  • Access to all packages from debian software repositories.
  • Debian repository hosted on http://pandian.openpandora.org so keep pandian scripts up to date
  • armhf means float operations are relegated to special hardware for this rather than taxing the main cpu (as with softfloat)

Requirements

  • Of course a Pandora ;) All versions fine?
  • SD card minimum 2GB ( was tested with 4GB )
  • A Linux or Windows PC for putting the install on the aforementioned SD-card.

Which version is right for you ?

There are two different versions of the "MARK2" release:

  • "normal" is intended for regular users, who want a easy desktop that just works.
  • If you don't like LXDE as Desktop you can change it, adding a user interface atop the minimal install is more advanced as setup of USB-Networking or interfaces for wifi is needed to do so.

pandian package ( the basis of "minimal" )

Core package which contains following features:

  • ACPI support for brighter/darker-buttons, for lid and for low-power-mode
  • first-use-wizard
  • automount ( for USB-Stick, external Hard-Drives etc )
  • alsa sound support
  • pdcmd

pandian-lxde package ( what is added to make it "normal" )

Meta package featuring

  • full desktop environment (LXDE)
  • Easy Wifi-Access trough network-manager
  • MediaPlayer ( mpd with gurlp )
  • nub-support
  • calibrator-application
  • After you download the files, verify the checksums to make sure the integrity of the file downloaded matches in being an exact copy of the file downloaded from the server
  1. open a terminal
  2. sha256sum ~/downloads/pandian - - -- .7Z (input where you have the file and the one you chose to download)
  3. make sure it matches the given md5sum, if not, try to download another copy.

Putting the downloaded image on SD-card

Linux

Verify your SD-Hardware

Check where your SD-Card is located. If you have an build in SD-Card-Reader this is normally /dev/mmcblk0p1 ( in Debian ) If you have an USB-Card-Reader this is something like /dev/sdc ( in Debian )

  • Open an Terminal and input "lsblk"
  • You get an list with the actual Block-Devices
  • The SD-Card should be as type disk

You can also try gparted to see which devices you have and identify the SD-card

Unzip
  1. Unzip with 7z ( in Linux with 7zr e <image.7z> )
Copy the image to the SD-Card
 Warning, this will destroy everything on the device ! So please be very sure which device is you SD-Card !



  1. Here it will be /dev/sdx

(note that its sd and then a letter, sdc for example not the following number, as that is the partition, we are using the base card here) This means considerations for partitions and filesystem are taken care of, so no need to worry about that. Do not pick the wrong drive however, since dd will happily write the image to somewhere it isnt supposed to if you tell it to)

  1. Copy image to SD-Card with "dd if=<image.img> of=/dev/sdx"

You now have Pandian installed on your SD card and its ready to go. :) However after copying the image to the SD-Card resizing the partitionspartitions is needed to fully utilize the space, since by default the install is limited to 2GB. (If your card is bigger Pandian is still limited to those 2GB)

Resize SD-Card
  • This can be done with gparted on linux|gnu
  • start gparted
The actual partitions of the SD-CARD. Please select the correct device at the top right corner.
Rightclick to the second partition and select Resize/Move
You see the actual Size of this partition
Move the slider to the right, or set "Free space following" to 0
After you press the "Resize/Move" button, you get the preview of the new partition structure
When you press "Apply all operations", youve got a warning that you can loss your Data.
THIS IS THE LAST CHANGE TO CHECK IF YOU SELECTED THE CORRECT DEVICE.
Press Apply if everything is correct.
  • After everything is fine, you have your new fresh Pandian on you SD-Card


Network Fix for pandian-minimal

If you download the pandian-mark2-minimal-hf_2014-01-02 image there is a lack of tools for setup wifi networking.

  • Therefore download the fix and place it on the SD-Card where pandian is installed.
  • Boot pandian-minimal
  • login with user: "root"
  • switch to root-directory: "cd /"
  • untar the network-fix: "tar -xf /path-where-file-is-located/pandian-mark2-minimal-networking_2014-01-03.tar.gz"
  • setup the fix with command "pdMinimalNetwork"
  • after the script is finished, run "ceni" and setup your wifi-connection

First-start

  • Upon first boot of Pandian, there is a first-start-wizard which guides you through some basic settings.

Locale, timezone, time and date, password for admin and user setup and calibration of touchscreen. Located in /usr/sbin/pdSetup should you need to run it again

Navigation

  • Inside a dialog you can navigate with the cross
  • With space you select a checkbox
  • Moving between <Ok> and <Cancel> can be down with the use of TAB ( Tap Fn then tap Space )
  • Acknowledge with Enter

Update ( Optional )

  • After you setup your Pandora, it is useful to update your system. It is a rolling release, which means since the image was made, the system is forever updated with new packages.
  • open a terminal
  • get root ( command is: "su" )
  • enter "apt-get update" to download package information from the repositories
  • enter "apt-get upgrade" to update all packages that are out of date

(pandian packages are also updated this way :)

Preinstalled packages

These are the packages which come with the different versions of MARK2:

minimal

Installation

note: It is assumed here, that the card-reader load the card as /dev/sdc. Please check before which device is your SD-card ! This can be checked with gparted. Minimum requirement 2GB SD-card.

  1. Download Image ( as 7z )
  2. Verify md5-checksum:
    pandian-stable-hf_2013-09-29.001.7z 2a85bbb40bbe7c6e8f92f058e150951a
    pandian-stable-hf_2013-09-29.001.img e62d101dc708de49af1ca7743e2df2bd
  3. Unzip with 7z ( in Linux with 7zr e <image.7z> )
  4. Copy image to SD-Card ( dd if=<image.img> of=/dev/sdx ) Don't specify "bs="

Username: Pandian
Root password: Root (change after intsallation as per instructions below)

  1. Open a terminal
  2. Type "su"
  3. Type "passwd"
  4. Enter your new root password when prompted, and then again to confirm.
  5. Dont forget your password

Resize

Default installation is limited to 2GB, if you want to expand it, you can, provided you have installed it on a bigger SD-card and want to make use of the space.

  • Size will be changed with parted
  • parted /dev/sdx
  • show size with "print free"
  1. (parted) print free # Model: USB Mass Storage Device (scsi)
  2. Disk /dev/sdc: 7965MB# Sector size (logical/physical): 512B/512B# Partition Table: msdos
Number Start End Size Type File system Flags
32,3kB 1049kB 1016kB Free Space
1 1049kB 53,5MB 52,4MB primary fat32
2 53,5MB 1933MB 1879MB primary ext4
1933MB 7965MB 6032MB Free Space

we would like to resize the second partition to the nearly end ( -512MB for swap )

  1. (parted) resizepart # Partition number? 2 # Warning: Partition /dev/sdc2 is being used. Are you sure you want to continue?# Yes/No? YES # End? [1933MB]? 7453MB this is how the partitions looks like after

(parted) print free * Model: USB Mass Storage Device (scsi)* Disk /dev/sdc: 7965MB* Sector size (logical/physical): 512B/512B* Partition Table: msdos

Number Start End Size Type File system Flags
32,3kB 1049kB 1016kB Free Space
1 1049kB 53,5MB 52,4MB primary fat32
2 53,5MB 7453MB 7400MB primary ext4
7453MB 7965MB 512MB Free Space

create Swap (optional)

(parted) mkpart primary linux-swap Start? 7453MB End? 7965MB

this is how the partitions looks like after

(parted) print free * Model: USB Mass Storage Device (scsi)* Disk /dev/sdc: 7965MB* Sector size (logical/physical): 512B/512B* Partition Table: msdos


Number Start End Size Type File system Flags

1 1049kB 53,5MB 52,4MB primary fat32
2 53,5MB 7453MB 7400MB primary ext4
7453MB 7453MB 278kB Free Space
7453MB 7965MB 512MB primary Free Space

disregard the 4th entry, the new resized partition is the last one.

resize filesystem

  • resize2fs /dev/sdc2

create swap

  • mkswap /dev/sdc3
