One idea I'd have is to properly get the AC100 working.
I'd be also interested in that (I also have an AC100, but no time to debug it yet).
I think Joop has already some image available?
Yes, the image I guess is not really the issue here.
Like Ubuntu, Joop has been using the marvin24s-kernel from gitorious. This is combined with an initrd into an Android Boot Image that the native bootloader understands.
Alex would like this to be replaced by a U-Boot that loads kernel and initrd from an actual partition and that kernel being the standard Factory kernel with appropriate config. Someone would need to diff a working ac100 kernel against the corresponding upstream kernel and forward-port it to 3.2 (or whatever 12.2 uses) and I've been lacking the time to do so.
There's a few pages on U-Boot attempts here: http://ac100.grandou.net/uboot http://pecourt.ovh.org/wiki-tegra/doku.php?id=uboot http://ac100.grandou.net/debian_uboot
I've build a u-boot-ac100 package. It can be found in: home:worldcitizen:armv7l. This also holds kernel-tegra-ac100 which includes uImage, needed for u-boot-ac100. I haven't tested this one yet. I've also created python-putusb in home:worldcitizen. Probably my worst package ever, I will improve this one. Instructions for usage can be found here: http://ac100.grandou.net/uboot http://ac100.grandou.net/putusb http://ac100.grandou.net/debian_uboot I still need to test this. From what I've read u-boot can tested without flashing it. I haven't had time yet to test this.
Kernels: http://ac100.gudinna.com/toshiba-gpl-source-code/ (2.6.36?) http://gitorious.org/~marvin24/ac100/marvin24s-kernel/commits/chromeos-ac100...
BTW if someone wants to add Tegra2/AC100 or Tegra3 emulation to QEMU I'd be willing to help mentor that. ;)
