Hello,
I disabled secure boot so I can run flashrom as root in my openSUSE Tumbleweed machine. It reported the following:
flashrom -p internal --wp-status
flashrom v1.3.0 on Linux 6.7.9-1-default (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... Disabling read write protection of flash addresses from 0xfc000000 to 0xfc05ffff failed. Disabling read write protection of flash addresses from 0xfd000000 to 0xfd05ffff failed. Disabling read write protection of flash addresses from 0xfe000000 to 0xfe05ffff failed. Disabling read write protection of flash addresses from 0xff000000 to 0xff05ffff failed. FCH device found but SMBus revision 0x51 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.
I also attached the output of `lspci -nnvx` as requested.
Best regards,
