On your Debian running computer type: (It should also work on Debian derivatives like Ubuntu)
debootstrap --arch armhf --foreign --variant=minbase jessie jessie-minbase-arm http://ftp.it.debian.org/debian/
this command creates a armhf debian tree in the subdir named "jessie-minbase-arm"
Then tar and send the dir on the chip9$:
tar cvf jessie-minbase-arm.tar jessie-minbase-arm scp jessie-min-arm.tar 10.1.1.2:/home
(10.1.1.2 is the IP address of my chip9$ wifi interface, put the proper value for your installation).
Now login to Chip9$ (e.g. using "ssh root@10.1.1.2"). and de-tar the tree.
cd /home tar xf jessie-minbase-arm.tar
now create some files:
echo nameserver 8.8.8.8 > /home/jessie-minbase-arm/etc/resolv.conf echo deb http://ftp.debian.org/debian jessie main > /home/jessie-minbase-arm/etc/apt/sources.list cat > /usr/local/bin/startchroot << ENDTAG mount --bind /proc /home/jessie-minbase-arm/proc mount --bind /dev /home/jessie-minbase-arm/dev mount --bind /dev/pts /home/jessie-minbase-arm/dev/pts/ chroot /home/jessie-minbase-arm /bin/bash umount /home/jessie-minbase-arm/dev/pts umount /home/jessie-minbase-arm/dev umount /home/jessie-minbase-arm/proc ENDTAG chmod +x /usr/local/bin/startchroot
Now everything is ready to enter the chroot environment:
startchroot
The prompt may appear something like:
I have no name!@chip:/#
Now the installation must be finalized inside the chroot tree:
DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true LC_ALL=C LANGUAGE=C LANG=C /debootstrap/debootstrap --second-stage
Now Debian is ready. It is possible to update the list of available packets and install all what you need.
apt-get update apt-get install aptitude aptitude install vim build-essential aptitude install python python3
It is possible to add a user:
adduser user
To "become" the user type:
su user cd
It is possible now to run the well-known "hello world" test (cat is to try the test using cut&paste, use vim if you like:
cat >hello_world.c <<ENDTAG #include <stdio.h> int main(int argc, char *argv[]) { printf("hello world from CHIP!\n"); } ENDTAG gcc hello_world.c ./a.out
The answer is:
hello world from CHIP!
If you exit from the chroot shell, you'll return in the standard busybox-based image environment currently available for flashing Chip9$.
Next time you boot chip9$, type:
startchroot
to enter the Debian chroot.
