Do you have any plans to support the laptops with QM67 chipset and AT25DF321A, AT25DF641A flashchips, to upgrade the bios gracefully? If yes, can you please give us the timeline.
Hello Raghu! the AT25DF321A is already supported, but untested (usually SPI chips just work). The AT25DF641A is almost identical to the AT25DF641 and will (for now) be detected and used as such. The latter is supported, but as well untested. I dont see a problem regarding those chips. In the event that a problem is encountered we can probably fix it quite fast. The other part of the question is not that easily answered. First of all laptops have additional chips (embedded controllers) involved in accessing the flash device which we dont support in general at the moment. This is a long term goal without a timeline (you could depend on). The chipset itself is supported. It just have some features that - if enabled - prohibit accessing some portions of the flash. There is some work done on working around this, but do not expect this to arrive soon please. I could tell you at least a bit more, if you could post a verbose output of running flashrom (including the laptop-enabling parameter of course). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
Thanks Stefan. The force option enable worked and we were able to program the AT25DF321A flash. But the contents are wrong and the board was not able to come up. Please see attached for the verbose output for both read and write. For your info, the board has two flashes(each 4MB) and the bios resides on the second(we have a jumper option to select the flash device). We are confused whether the flashrom selects the correct flash device and program it. Can you please help.
