The under development Software Kit working as a "LiveDVD" or installed and running off a disc. This DVD is kubuntu based GNU/Linux distribution with some additional software and preconfigured settings.

The idea is to bring our customers a GNU/Linux distribution customized for use with our cameras, with the option of either installing it on their computers or using it as LiveDVD. For more advanced users and developers we have provided many tools to cross-compile, simulate FPGA code, reflash the camera, etc.

This page describes the content of the LiveDVD and instructions on use and customization.

ChangeLog:

25 Nov 2007: first beta release

http://community.elphel.com/files/Elphel-Software-Kit.iso

• beta DVD to be tested by developers and some of our wiki users

DVD content:

Our DVD differs from the standard kubuntu distribution in several way:

• It includes all software needed for use of our cameras.
• We have added some video editing & images processing software.
• It includes software for software and hardware developers.
• Some configuration files are modified to suit our needs.
• We have added some OpenSource applications for Windows (R).

User software

For users we provide:

• Flashit icon on the desktop to reflash our cameras with the latest firmware.
• Firefox web browser with mplayer and genres plugins to provide live view of our cameras.
• LAMP based DVR to provide a simple way to record video and audio from our cameras.

• cinepaint
• ImageMagick
• gocr
• mjpegtools
• avifie-utils
• ElphelSrv
• DVR software

Elphel SDK

We provide our clients with a complete SDK to develop software, FPGA code and even to redesign the hardware.

IDE:

• Eclipse IDE
• VDT verilog plugin for Eclipse IDE

CAD:

• Qcad
• Varicad (demo)
• Kicad

FPGA:

• iverilog
• GNURadio
• GTKWave

Other:

• dash shell is replaced with bash to comply with Axis SDK

Remastering the DVD:

Our distribution is based on Kubuntu GNU/Linux. You can remaster it from Live session with an external hard-drive or after installing our base distribution on your computer. From here I am assuming it's installed and you have sufficient space (~6 GO).

So here is the modification process:

prepare the environment:

sudo su
cd
mount /media/cdrom
mkdir remaster-root remaster-iso  remaster-new-files tmp
cp -R /media/cdrom/* remaster-iso
mount -t squashfs -o loop,ro remaster-iso/casper/filesystem.squashfs tmp
cp -R tmp/* remaster-root
umount tmp
rmdir tmp

modify the distribution:

mount --bind /proc remaster-root/proc
mount --bind /sys remaster-root/sys
mount --bind /dev remaster-root/dev
chroot remaster-root
#install your software, remove unneeded software modify configuration files, ...
apt-get remove nano
apt-get install vim
apt-get clean
exit
umount remaster-root/dev
umount remaster-root/sys
umount remaster-root/proc

rebuild the DVD:

chroot . dpkg-query -W --showformat='${Package} ${Version}\n' > ../remaster-iso/casper/filesystem.manifest
chroot . dpkg-query -W --showformat='${Package} ${Version}\n' > ../remaster-iso/casper/filesystem.manifest-desktop
mksquashfs .  ../remaster-iso/casper/filesystem.squashfs
cd ../remaster-iso
find . -type f -print0 |xargs -0 md5sum |sudo tee md5sum.txt
mkisofs -o ../remaster-new-files/Elphel-Software-Kit.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -r -V "Elphel Software Kit" -cache-inodes -J -l .

That's all :) you have a new DVD image in /root/remaster-new-files/Elphel-Software-Kit.iso

TODO:

• Do a better network detection/setup what I did (look to /etc/rc.local)
• Check and make completely work the DVR
• Repair the grub message on boot of the LiveDVD
• Check all functionalities that should be user-friendly.

Ideas:

This DVD is based on KUbuntu 7.04. I will work on upgrading our distribution.

I think it should be useful to debianize all our software (ElphelOgm, GenRes, MPlayer, ...) Like what we will be able to use Launchpad PPA https://edge.launchpad.net/~elphel-live to build our Ubuntu packages as i tried on : https://edge.launchpad.net/~polto/+archive I have here a working MPlayer what can be installed by Sinaptic (the user-friendly way) just after adding my personal package repository to your sources.

So any Ubuntu user will be able to upgrade to our MPlayer, install ElphelSrv, ...

After what we can make some theme packages with backgrounds etc and generate a DVD with everything installed.
