[okl4-developer] about arm920t core

[Carl van Schaik]

Hi Quanlong,

It looks as if you are loading the image.bin file, which is not an ELF
file. Thus you should not use bootelf.
As Geoffrey pointed out, you should also be using the image.boot instead
of image.elf. If you want to load a binary, use arm-linux-objdump -O
binary image.boot image.bin
then in u-boot you need to run "go 0x30000000" instead.

If you load the image.boot file, then you can run bootelf, but you need
to ensure that the address you load the image.boot ELF file does not
overlap any addresses in the image, otherwise you will overwrite the ELF
file in memory when loading from it.

regards,
Carl
