Re: [U-Boot] booting os 'Unknown OS' (1) is not supported

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.
