I have an Intel's ATOM Bay Trail board. The output of "inteltool" is:
CPU: ID 0x30679, Processor Type 0x0, Family 0x6, Model 0x37, Stepping 0x9 Northbridge: 8086:0f00 (Bay Trail) Southbridge: 8086:0f1c (Bay Trail) IGD: 8086:0f31 (unknown)
In coreboot configuration I selected: Mainboard -> Mainboard model -> Bayley Bay FSP-based CRB The default ROM chip size is 2MB. This is also the size of coreboot.rom created after "make"
The board has 8MB BIOS flash. It's delivered with a BIOS programming utility that runs under EFI shell.
is your board related to the Bayley Bay CRB? or is it just a random new Bay Trail board? I'm not sure how much Bay Trail boards differ, but usually you have to adapt a lot settings in coreboot for a new board (like the ROM size). I always advice to check the GPIO and other pin settings first, before trying to boot a new board.
The original BIOS has 2 versions: rom (5MB) and bin (8MB) I tried to burn the 2MB coreboot.rom with the vendor's BIOS utlity.
That's not a good idea. In case the board doesn't boot anymore after- wards (which is likely for a first shot), you need an external flash programmer anyway.
