Main Features

The debian way.
Access to all packages from Debian software repositories.
Pandian hosts its own Debian repo http://pandian.openpandora.org with up to date scripts, all settings and extra programs.
armhf-build, which means float operations are relegated to special hardware rather than taxing the main cpu with them (as with softfloat)

Pandian - MARK 2 The newest release

Second version of Pandian
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

Installation requirements

Pandora ;) All versions fine?
SD card minimum 2GB ( was tested with 4GB )
PC Linux|GNU, BSD, Mac, or Windows for putting the install on the aforementioned SD-card.

Download a version of Pandian

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

Version	Description	Includes	Link	Checksums (sha256)
normal	pandian for regular users, with full Desktop environment ( LXDE )	network-manager MediaPlayer ( mpd with gurlp ) nub-support calibrator-application medit Text editor. mpd audio player backend, glurp as frontend	filedropper: pandian-mark2-hf2014-01-02 pandian.openpandora.org: pandian-mark2-hf_2014-01-02.7z	pandian-mark2-hf_2014-01-02.7z 3731d70a4d8ec59e79a046f34f69c5c809be73e38cfc91a5b580478b8f8c222f pandian-mark2-hf_2014-01-02.img 83b8d3fa5bd0588cfb8b11cfe6b827819e6311e98396a6e32c46c9692f072e96

Notes:

It is trivial to change from LXDE to Xfce (or any other desktop environment), adding a new user interface atop the minimal install is more advanced as manual setup of USB-Networking or wifi is needed to do so.
All images have automount ( for USB-Sticks, external Hard-Drives etc. ) and ALSA sound support

Verify that your download is OK

After you download the version you picked, verify its checksum to make sure the integrity of the downloaded file matches (in being an exact copy the one on the server)

open up a terminal
"sha256sum ~/downloads/pandian/<image.7Z>" (input where you have the file and the one you chose to download)
make sure it matches the given md5sum, if not, try to download another copy. This step isnt mandatory, but its there to make sure everything is fine before we proceed.

Unzip the downloaded image

Unzipping 7z archives

Open up a terminal (or do it your way)
Enter"7zr e <image.7z>"
You now have an unzipped image

(Optional) Preparation, find out where to install

This step helps you find out where the SD card is mounted.

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 will get a list with the actual Block-Devices
The SD-Card should be of type 'disk'

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

Install the image to the SD-Card

Here it will be /dev/sdx

(note that the x after the sd is the drive letter, it could be sdb sdc or sdd and so on, lets say its sdc. Which means c is the drive letter for the SD-card and that sd- a and -b are in use for other things.

When writing to the device, make sure not to include the following number, which is the partition sdc1 sdc2 etc. since 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 isn't supposed to if you just give it root privileges and hit enter.)

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)

(Optional) 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 a fresh install of Pandian on you SD-Card

Startup wizard

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

These are: Locale, timezone, time and date, password for admin and user setup and finally calibration of the touchscreen. The script is located in /usr/sbin/pdSetup should you need to run it again.

Navigation

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

Network connection instructions:

normal

Use network-manager

minimal

Use ceni network manager

(Optional) Update of Pandian system

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 :)

Note: to update only the pandian-packages enter "apt-get upgrade pandian*"

Upgrade from "minimal" to "normal"

It is possible to upgrade from the "minimal"-image to the "normal"-image. This can simlpy be done by installing the pandian-lxde debian package

get an connection to the internet(tm) with ceni
open an terminal
get root ( with command: "su" )
update package list with: "apt-get update"
install debian-lxde with "apt-get install debian-lxde"

(Optional) Information

Additional Users/Groups

There are additional Users/Groups added to the standard debian-users

Groups

admin

This superuser privilege is used by sudo for admin task like shutdown etc.

mpd

This user/group has access to mpd-related files ( socket, pid-files )

Power-Modes

LID-Close

If the lid is closed only the screen will be disabled

Low-Power-Mode / Shutdown

Switch

Switch to left: Pandora will go to low power mode ( reduce CPU, Disable LID, Pause processes )
Switch to right: Shutdown the pandora

pdcmd

This script handles all system-related stuff, like lid, low-power, usb or wifi.
This should run as root

Usage:

Command	What's done
/usr/sbin/pdcmd LCDBright +	Increase the light of the lid
/usr/sbin/pdcmd LCDBright -	Decrease the light of the lid
/usr/sbin/pdcmd LCDBright 10	Set the Brightness of the lid to 10
/usr/sbin/pdcmd LCDTrigger	Trigger the lid ( WARNING: THIS DISABLES THE LID ! )
/usr/sbin/pdcmd USBNetTrigger	Enable the USB-Networking (module g_ether). If usbnetworking is on, it will disable it
/usr/sbin/pdcmd USBHostTrigger	Enable the USB-Host (module ehci-hcd). If USB-Host is on, it will disable it
/usr/sbin/pdcmd WLANTrigger	Enable Wifi. If Wifi is enabled it will be disabled

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.
Note: For the actual download of pandian-minimal, wifi-network-tools are included

Therefore download the fix and place it on the SD-Card where pandian is installed. (you need to have local superuser privileges on your own system as the SD contents aren't owned by your user)
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

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"

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

2	53,5MB	1933MB	1879MB	primary	ext4

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

(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
