I have kept hoping that I'll se flashrom working with that AM4 board, but so far, no luck.
Is tehre some kernel option that is instrumental for flashrom ? I do have I2C compiled in the kernel etc ( gentoo-sources ) etc.
Similar OS stack on AM1 board works fine...
I did set up the SPI cable and SPI FLASH on a socket on the front page of my mashines, so I cen reprogram the chip in other maqchiens if/when needed, but it it's awkward.
Siple "flashrom -p internal" returns:
*** flashrom v1.2-106-gcb9f3cd on Linux 5.8.11-gentoo (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@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. ***
