Hello
I tried today to back up my actual bios and got a result as you can see below:

tianlou@avocette:~$ sudo flashrom --programmer internal --read bios.backup
flashrom v1.2 on Linux 5.10.0-11-amd64 (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.

tianlou@avocette:~$ lspci -nnvx
