Thanks, I'll give that a try. I should have clarified "my processor" a
little more. It's a Cirrus Logic EP9312 and yes indeed there is a boot
rom internal to the processor that does these checks for a signature
that I've put in this header. Essentially it's a way for it to determine
if there's a valid image in flash to boot from, otherwise it tries to
boot from other interfaces. 

I certainly didn't want to do a global change to a Makefile for
something like this.

Regards,
Adam

Dear Adam,

Your _processor_? I never head something like that. Are you sure it's
not another existing boot loader on your system?

Me too, and it's actually easier that way. trun your binary header in
an object file and edit the linker script for your board to load this
object first.

Best regards,
