[U-Boot] AM3703 Overo SPL/u-boot booting woes

[Charles Manning]

Hello All

I am trying to use SPL to boot an AM3703-based overo board from NAND.
SPL runs and seems to load u-boot correctly but u-boot does not run
correctly.

When I use the same SPL and u-boot from MMC, everything boots fine.

I have modified SPL slightly to add some extra debugging.

Any ideas what's wrong?


Boot from MMC looks like:

>>board_init_f()
>>spl:board_init_r()
boot device - 6
OMAP SD/MMC: 0
reading u-boot.img
spl: payload image: U-Boot 2011.12-00475-g92216bd-di load addr:
0x80007fc0 size: 25822
reading u-boot.img

etc... all the way to Linux.




Boot from NAND looks like:

>>board_init_f()
>>spl:board_init_r()

spl_nand_load_image()

and then nothing.

Thanks
