Read & Write seems ok for this Atmel. I've checked using a factory bios.bin and also writing a linuxbios.rom file. Boots with flashing with a factory bios.bin. So this chip is probably well tested here. :-) > > STMicroelectronics M29F002 256k Problematic. I see the patch provides addresses for this chip instead of using the jedec_probe for probe/read/write functions. Altering the addresses for teh MDF002* chips to use the jedec_probe functions seems to work. I have test read the MDF002T chip here. I don't want to write to it because it's the chip that came with this board. On a side note, both of these chips, I do # ./flashrom -r test.bin # diff /dev/mtd0ro ./test.bin or # cmp /dev/mtd0ro ./test.bin Both tests state the files differ or EOF. But if I do: # dd if=/dev/mtd0ro of=./test.bin #diff /dev/mtd0ro ./test.bin diff states the files are the same. <shrugs> I'm probably doing something wrong here. :-/ > > Sure, please try attached patch and report whether it works (if so, > please send an Acked-By).
