Our custom board MLO can't boot correct , hang in second read u-boot.img stage.
I know maybe is hardware issue , but i don't have any idea to check what happen.
==== Error ===============================================================
in mmc_load_image_fat() function :
file_fat_read #1(64 Bytes) -> Read u-boot.img header
reading u-boot.img to address : 0x800fffc0 , size : 64
...................
spl: payload image: U-Boot 2011.09 for am335x board load addr: 0x800fffc0 size: 259200 -> spl_parse_image_header() can parse correct info.
When return mmc_load_image_fat() , i try show the spl_image struct info :
debug("*** spl: payload image: %s load addr: 0x%x size: %d\n", spl_image.name, spl_image.load_addr, spl_image.size);
The result is : *** spl: payload image: <NULL> load addr: 0x0 size: 0
reading u-boot.img to address : 0x800fffc0 , size : 64 -> I try fix the load_addr in 0x800fffc0
