Hi, yeah, I know it's an ancient thread, but it's a current topic for me as I started a second go in converting my AC100 from Ubuntu Precise (armel) to Debian (armhf), this time to Wheezy and successfully. (Yay! :-)
And I still have one question: Which kernel to use? The most update -ac100 kernel I found was Julian's 2.6.38-2-ac100 in his repo at http://people.debian.org/~jak/ac100/ -- the kernels available in Wheezy are: linux-image-3.2.0-4-mx5 - Linux 3.2 for Freescale i.MX51/53 linux-image-3.2.0-4-omap - Linux 3.2 for TI OMAP3+ linux-image-3.2.0-4-vexpress - Linux 3.2 for ARM Ltd. Versatile Express Would the armmp images from Sid/Jessie/Wheezy-Backports work on the AC100, too? The short description says "Linux for ARMv7 multiplatform compatible SoCs". "cat /proc/cpuinfo" says: Processor : ARMv7 Processor rev 0 (v7l) processor : 0 BogoMIPS : 1992.29 processor : 1 BogoMIPS : 1998.84 Features : swp half thumb fastmult vfp edsp vfpv3 vfpv3d16 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x1 CPU part : 0xc09 CPU revision : 0 Hardware : Toshiba AC100 / Dynabook AZ Revision : 0000 Serial : 0000000000000000 But then again that package's long description says "The Linux kernel 3.10 and modules for use on ARMv7 multiplatform kernel for Marvell Armada 370/xp, Freescale iMX5x/iMX6." There's no mention of Nvidia Tegra stuff.

I can answer that myself: the parameters are in /boot/bootimg.cfg and flashing happens while installing flash-kernel. Not sure what I did wrong the last time: > I currently have Ubuntu on the eMMC and bootstrapped Debian armhf to > an SD card (never booted, no idea where to tell the system to suddenly > boot from SD instead of the eMMC. It seems only the root= parameter in the bootimg.conf. > Is there a way to choose between the two install operating systems? Seems not the case. I'd currently reflash /dev/mmcblk0p2 with the Ubuntu kernel, initrd and bootimg.conf with abootimg. You can either use abootimg to directly write the boot image to /dev/mmcblk0p2 or to write it into some file on some other device and then flash it using Nvidia's nvflash tool. (I've not done the latter for a long time.) I'll try to update https://wiki.debian.org/InstallingDebianOn/Toshiba/AC100, especially with regards to amrhf no more being on debian-ports.org. P.S.: I still have occassional freezes. I had them with Ubuntu Precise if I logged in (but far more seldom if I just left lightdm's login screen running and accessed the box via SSH) and I had them on Debian after a few minutes until I switched the I/O scheduler from cfq to noop. Since then, I only had one more freeze. But then again that box only has not that much uptime over all yet...
