Hi coreboot and flashrom,
I recently got a Gigabyte GA-J1900N-D3V-1.x board. This board is interesting to me because A) it's Bay Trail, B) it's got dual NICs and real serial ports, and C) it's inexpensive. I followed the guide at
http://www.coreboot.org/Motherboard_Porting_Guide
I put the logs and a README with more info at
http://lackof.org/taggart/hacking/coreboot/GA-J1900N-D3V-1.x/
(and a tarball of that dir in the parent dir)
The flashrom output is from SVN trunk as of today to ensure latest chip support. In particular flashrom reports untested:
Found chipset "Intel Bay Trail" with PCI ID 8086:0f1c. Found Macronix flash chip "MX25U6435E/F" (8192 kB, SPI).
I haven't yet attempted anything beyond that. I don't yet have an off-board way to flash the chips, I'm hoping to order something soon. If you have ideas of other things to try please let me know.
Thanks,
