While doing the internal flashrom operations, that BIOS chip is situated behind a southbridge that you find by AMD FP4 name. Looks like either its' support isn't good enough at flashrom or UEFI firmware / EC controller somehow disturb the operation. Maybe try to access a BIOS chip directly with the external programmer like usb ch341a?

I'm just trying to read what bios info I can:
MSI X570-A PRO (MS-7C37) AMD Ryzen 7 3700X FreeBSD fbsd13 13.0-CURRENT FreeBSD 13.0-CURRENT
root@fbsd13:~ # flashrom -p internal flashrom v1.2 on FreeBSD 13.0-CURRENT (amd64) flashrom is free software, get the source code at https://flashrom.org
Using clock_gettime for delay loops (clk_id: 4, resolution: 1ns). Found chipset "AMD FP4". Enabling flash write... 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.
pciconf -lvb output attached, as well as flashrom -V -p internal (the verbose version)
My first question is: It looks to me that "AMD FP4" is just a BGA (FP4) Socket, not a chip. Newbie to flashrom & coreboot.
Thanks, Clay
