Using Nokia 770 as Debian/Arm porting machine
Nokia 770 is a debian-based "internet tablet". The system is resource-constrained, so it has a seriously stripped Debian implementation. One way to use 770 for fully featured Debian development is via a nfs chroot on a host system.
Setting up the chroot
On a host system:
debootstrap --foreign --arch arm sid /var/arm-chroot http://ftp.es.debian.org/debian
Export nfs in /etc/exports on the host computer.
Setup the 770 in r&d mode by running flasher on the host system.
Boot the 770 and finish the debootstrap (xterm needed on the 770):
$ sudo gainroot # mount -t nfs -o nolock,rsize=1024,wsize=1024 192.168.2.14:/var/arm-chroot /nfs # chroot /nfs /debootstrap/debootstrap --second-stage
TODO: figure out optimal nfs setttings -these are REALLY slow
Have a nice cup of coffee. The second-stage above will take a while, around an hour. So maybe have a lunch as well.
Using the chroot
# chroot /nfs
And then just use it as normal Debian development enviroinment:
# apt-get install build-buildessential # apt-get build-dep foo # apt-get source foo # cd foo-version && dpkg-buildpackage -b
Setup swap - many apps/compilers take lots of RAM
direct initfs -> nfs boot to reclaim more memory
- Figure out why the kernel crashes sometimes with nfs
- Guide for IT2006 edition (nfs support removed from kernel, need to build more modules)
- ready-build IT2006 OS debian package to automate the whole setup possible
- armel support as well
- sbrsh as well
