flashrom v1.2 on Linux 6.0.12-arch1-1 (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 0x61 does not match known values.
Please report this to [e-mail] 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.

Thanks!
