Need help booting to SD card for Pogo V4, stuck at "Starting kernel ..." (9 replies)

I have the Pogo V4-A1-05 (which should be the same as Pogo V4-A1-01)

I collected and followed the instructions to boot up via the SD card. The SD card has the ArchLinux image from http://archlinuxarm.org/os/ArchLinuxARM-armv5te-latest.tar.gz. This image booted fine with the USB drive.

I installed davy's uboot and Jeff's envs according to Bodhi's instructions here:

I have netconsole working. After getting the netconsole prompt, I manually entered each step tracing through the bootcmd.

I called:
> mmc init;
> mmc init;
> run mmc_set_bootargs;
> run mmc_boot;

I get the following output after calling mmc_boot:

-----------------------------------------------------------------------------

Here's my env:

(Ignore the "mtd" variable; I messed up when setting "mtdparts")

The Pogo has a stable green light (non-blinking), but I cannot ssh or ping into the machine. It has a static IP.

Is there a recommended rootfs image that I can install on the SD card? It seems uboot recognizes the card and can read the image, but for some reason it can't start the kernel...

What could be wrong? Any ideas on how I can debug this further?
