Can you do an 'mkimage -l <image>

Hi Alexander,
[...]
*ERROR: booting os 'Unknown OS' (1) is not supported*
Hm, very strange. Looking up the code, the '1' is the image type contained in the uImage header. It is defined to be OpenBSD in include/image.h and if your U-Boot doesn't have support for that, you will get that message. This however doesn't make sense to have an uImage with this type.
Can you do an 'mkimage -l <image>' on your development host to check the contents of the header? If this looks good, then somehow the image seems to be overwritten before trying to boot, but I don't see where.
Cheers Detlev
