that linux-image-3.1.0-1-mx5 was not found.

unstable is using 3.2:

Thank you for this hint. I was able to build an image and dd'ed it to the micro SD card. On the serial console I could watch the boot process but noticed some warnings and errors:

[ 1.248177] /build/buildd-linux_3.2.21-3-armhf-ki0aTS/linux-3.2.21/drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

As far as I can see the second revision (-R) of the loco board is not properly supported. The vanilla kernel lacks (at least) the MC34708 PMIC related drivers. So USB and sometimes VGA are not working properly.

I tried to backport the MC34708 patches from the Freescale kernel tree but gave up because the trees diverged too much.

The necessary patched can be found here (2011-10-27):
http://opensource.freescale.com/git?p=imx/linux-2.6-imx.git;a=shortlog;h=ed5a15000f0a8c09b68bdff46906790dcbd01a0a;pg=1

I also made the mistake to flash the Wheezy image to a micro SD card and tried to boot from the SATA disk with the Debian u-boot. Unfortunately it lacks SATA support for the loco board (This was introduced in a later u-boot version than the one on Wheezy).

I wonder if it's possible to use the Freescale 2.6.35 kernel to run the Debian armhf port. Will this work? Or must I use the armel port?

Thanks for your help!
Gregor
