[ECOS] RedBoot for Assabet (strongarm) problem

Hi Jesper,

Yes the flash is 32 bits width but I don't think this is the problem :
I've got a running binary of redboot and mine non working binary.

I've checked with hexdump and the bytes seems to be properly ordered in both files :
working redboot.bin :
0000000 f018 e59f f018 e59f f018 e59f f018 e59f
0000010 f018 e59f 0000 0000 f018 e59f f018 e59f
0000020 0060 0000 037c 5000 0400 5000 0438 5000

non-working redboot.bin :
0000000 f018 e59f f018 e59f f018 e59f f018 e59f
0000010 f018 e59f 0000 0000 f018 e59f f018 e59f
0000020 0040 0002 0128 0002 01ac 0002 01e4 0002

Thanks
Eric
