Why don't you try to make an ebuild for Axis' cris-dist-glibc ?

I have created a crossdev crisv32-axis-linux-uclibc. Glibc was broken on another point in the middle of compilation. Now I'm trying to actually get a normal program to compile with the toolchain just made. And to answer your question, to get the axis compilation to work is trivial, I made a hello world with that, but it is not trivial is to compile things with an old GCC ;) So if this works it gives me an uclibc system, I can run the camera from and a cross compiler to make software. And I presume crisv32 is more optimal than cris.

As far as I know cris and crisv32 are different arch. EtraxFS is crisv32.
About testing the rootfs... It's safe. The camera is unkillable. :) You can boot in a network boot mode and reflash the camera.
The network boot loader is build in to the EtraxFS SoC. To put the camera in this mode you have to power-up-down-up the camera 6 times with a 3 second delay between each operation. More on this in the beginning of http://linuxdevices.com/articles/AT5102023409.html

...I really think I should connect the serial cable and become a professional embedded user ;) Does it do TFTP? Or is the network boot something proprietary?
