All Elphel cameras are packaged with a DVD what can be used as a Live DVD or installed on the disc. This DVD is kubuntu based GNU/Linux distribution with some additional softwares. This page describe the content of the DVD, how to use and customize it.

The idea is to bring to our users a GNU/Linux distribution what whey can use with our cameras installing it on they computers or using it as LiveDVD. On the other side it provide more advanced users and developers with many tools to cros-compile, simulate FPGA code, reflash the camera etc..

DVD content:

  • mplayer
  • genres
  • ...

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. Here i suppose what it's installed and you have sufficient space (~6 GO).

So here is the modification process:

prepare the environment:

sudo su
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 softwares, remove unneeded softwares modify configuration files, ...
apt-get remove nano
apt-get install vim
apt-get clean
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 .

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