Did you use FMU to upload the bios?
Is that why you need that extra 0x40 bytes at the beginning, for the FMU
header?
This header is used by the Angel-PBL to load/run the content of the bank, right?
What about shortcutting the PBL and burning th BIOS in Bank 0, without the FMU
header and with TEXTADDR = 0x410000a0?
Wouldn't the BIOS own crt0.S initialization be enough to replace the PBL?
There was a big discussion in the Mail Archive around February/Mars 1999 about
the different intialization role of the BIOS and the kernel respectively. I
never found the definitive conclusions.
What initialisation should be under the control of BIOS and what should be
under kernel's control?
