OK with a Logic Analyser plugged on the EBSA, we discovered that the PLB
is not in agrement whit the checksum we add in our home made FMU header
generator. We suspect that we might have problem with the last bytes of the
images in FLASH (we assumed unwritten FLASH bytes were at 0xFF values).
Indeed, both the bios and bios.elf images have sizes that are not word aligned,
due to sections that are not word aligned themselves:

>bios.elf: file format elf32-littlearm

I feel especially suspicioud about a .text section of size 6b9f!
Isn't this supposed to be code always aligned?
(I may be totally wrong here i'm not familiar with these sections stuff)
Anybody has an idea?
