			...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?

			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

And I presume crisv32 is more optimal than cris.

New page

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