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". 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 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?
