Correct by default i have the SD card driver built-in (along with most sane disk formats extX).. I'm assuming most users won't have a secondary arm system around, or require them to install qemu to build an actual initial file system. So for the wiki's there's really not a quick/easy way to generate an armel initramfs on and x86 host.. But once you get the board running the first time, there's nothing stopping you from rebuilding a new kernel and generating a matching initramfs on the target.. > I also presume the same approach will not work if I was to boot the iMX53 on > Debian off of the SATA drive.

Reading the u-boot list, i belive this is on the horizon, otherwise there's nothing stopping you from having the boot files on teh sd card and the rootfs on the sata drive.. > Do you know of instructions similar to what you put together that describe > the process of booting the iMX53 on an attached SATA drive with a minimal > install of Debian? There's really not much difference, instead of just say "/dev/sdcX" for the boot and rootfs partitions on an sd card.. You'd have "/dev/sdcX" for the boot partition on the sd card and "/dev/sddX" for the rootfs partition.. (As long as your bootscript points to /dev/sda1 vs /dev/mmcblk0p1, and your /etc/fstab is adjusted accordingly).. > I'm actually still waiting for my iMX53 hardware to arrive, but I'm just > reviewing all the steps necessary to get it running ahead of time so I can > work with it as fast as possible. Not a problem, they are actually pretty nice boards, and the mainline kernel supports quite a bit on the board (ethernet and sata* with usb on the way..).. *still haven't figured out the correct config options to make it work..
