we want to participate again in FOSDEM 2020. Location: Brussels. Date: 1&2 February.
Own developer room: Expired...
Stand: 1 November
Main track talk: first batch 11 October, second batch 8 November
Lightning talk: 22 November
Talk/Demo in foreign devroom: probably end of October
If you want me to submit a stand request for a combine coreboot/flashrom/LinuxBoot stand, please have someone volunteer as backup organizer. We also need stand volunteers.
Side note: Should we reach out to the OpenBMC/u-bmc communities?
I tried to read my mobos bios, got this message.
sudo flashrom --programmer internal -r ASRock_B450_test.bin
flashrom v1.1-rc1-70-g71b706f on Linux 5.2.14-arch2-1-ARCH (x86_64)
flashrom is free software, get the source code at https://flashrom.org
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found chipset "AMD FP4".
Enabling flash write... FCH device found but SMBus revision 0x59 does not
match known values.
Please report this to flashrom(a)flashrom.org and include this log and
the output of lspci -nnvx, thanks!.
Could not determine chipset generation.PROBLEMS, continuing anyway
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.
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:
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.

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
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!
We're attempting to update our device using flashrom v1.1-rc2 and it does not update successfully. Attached is the verbose report as requested by the output.
The board we're using is based on the DFI KU171/173, with Intel Kaby Lake i3-7100U CPU, Intel 100 Series Chipset Family LPC Controller/eSPI Controller (PCI id 8086:9d4e. BIOS flash memory is Winbond W25Q128FV.
Please let me know if there is any further information required.
