Re: Mac Pro Mojave with AMD RX580 need to fix ROM for boot screen.
by Mike Banon 10 Sep '19

Dear Ray, Sorry, but I am quite sure that you will not be able to successfully flash a memory chip of your video card using the flashrom's Internal flashing mode, especially on a Mac: even the internal flashing of its' own BIOS chip is likely not supported (if a chipset isn't) and could result in a (software) bricking. So, most likely you'll have to use the external flashing adapter, like USB CH341A, which hopefully could be connected to a memory chip of your video card using a test clip (to avoid the soldering). Then, the command line will look like sudo ./flashrom -p ch341a_spi -r dump.bin -V And you could find an example of flashing setup here: http://dangerousprototypes.com/docs/Flashing_a_BIOS_chip_with_Bus_Pirate#CH… I am sending a copy of this e-mail to a flashrom mailing list, just in case someone would see a mistake in my message and would like to clarify or add some useful info.

does general bitbang support exist?
by Steve Maher 06 Sep '19

06 Sep '19

I've been googling and perusing the source tree, but am still unsure if general bitbang support is present in flashrom. Specifically, I have a board which has an onboard FT2232H with some of the GPIO pins wired to a SPI flash device. The pins used are NOT the MPSSE SPI pins from the 2232, but rather some other unused GPIO pins (the MPSSE dedicated pins are being used for JTAG, and the other 2232 channel is being used for data transfer), and I can't change the wiring from the 2232 to the SPI flash. Does flashrom support this type of configuration? If there is general bitbang support, I can write the necessary routines to control the pins of the 2232 in a bitbang fashion. Any pointers here would be much appreciated. Thanks for a great tool! Steve

Kaby Lake R - not detecting chip & size correctly
by Rafael Send 26 Aug '19

26 Aug '19

Hi there- I'm running a custom Thinkpad X210 motherboard, which has a Kaby Lake R on it. The default flash chip is 8MB, and is detected as "Opaque Flash Chip" with the correct size, and it flashes correctly. It's an MX25L64 When I replace it with a larger chip (32MB in this case), the detected chip is still the same as before (Opaque flash chip, size 8MB) but the new chip is a MX25L256. This actually works out great for using the same old images and swapping between chips, but I can't flash anything bigger if the size isn't detected correctly so it defeats the purpose of what I'm working on. What can I try to get the chips to be detected correctly? Alternatively, are there any logs or messages I can collect that would help folks on this list add chips or debug this? Thanks, Rafael
