That was the problem. It's booting now.
Thanks everybody,

- Leonid,
One more suggestion: did you untar the sample filesystem as root? Or did you untar it as a normal user?

It does boot with a MLO and uboot built from the repository. Just need to put our
SPI changes back in.

The error message you see about "Error - Factory Configuration Invalid" is because the u-boot you downloaded is... - 11:21 AM Software Development: RE: 3352 Module can't boot. Unknown memory type.
- Tim,
The error is using the latest mlo and uboot from the Critical Link website.

All the 3352 based modules use DDR3, so will all require the new u-boot.
cheers
