flashrom is free software, get the source code at
https://flashrom.orgUsing clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found chipset "AMD FP4".
Enabling flash write... FCH device found but SMBus revision 0x71 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.
Due to the high number of cores of the associated CPU, please find the output of the lspci -nnvx attached as a .txt file
