That's probably because you have hardware that's known not to be supported currently: https://flashrom.org/release_notes/v_1_5.html#known-issues

Hi,

I have an ASUS PRIME X370-A and wanted to make a raw flash image of the BIOS chip, to no avail:

root@ubuntu:~# flashrom -p internal
flashrom unknown on Linux 6.8.0-41-generic (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".

FCH device found but SMBus revision 0x61 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.

See attached lspci dump!

Seems to be a bug, hope it can be fixed, or is there something I overlooked?
