Hey, So I tried to update my ASRock B450 Pro4 Mobo with my custom modded bios using flashrom via GRML live iso on Ryzen 3600 Sadly that did not work and here's the result: root@grml /media/samsi/afuEFI # flashrom -p internal -r B45P4_5.00 flashrom v1.2 on Linux 5.10.0-8-686 (i686) flashrom is free software, get the source code at flashrom.org 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 0x61 does not match known values. Please report this to email@example.com 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. 1 root@grml /media/samsi/afuEFI # � Here is the output: termbin.com https://termbin.com/kvv8 I am using flashrom v1.2 on Linux 5.10.0-8-686 (i686) flashrom is already the newest version (1.2-5). (The same one provided with latest grml ISO file) Please let me know when flashrom will work for my mobo and CPU Best regards, olokos.
