|

Make sure your ROM base does not include any file-header
|
||||
information that is prepended to the kernel.
|
||||
|
||||
For example, the bootable U-Boot format (created with
|
||||
mkimage) has a 64 byte header (0x40). So while the image
|
||||
you write to flash might start at say 0x20080000, you have
|
||||
to add 0x40 to get the kernel's ROM base as it will come
|
||||
after the header.
