Alan K.L. Mok:
Can you please advise how I can achieve my goal? Should I go purchase a hardware flash programmer and mess with it (I don't have any electronic knowledge)? I searched the net and found "Bus Pirate", am I correct to say that it is a programmer/debugger that can talk "directly" to the chip? Would this possibly help in my case?
Motherboard : ASRock X300M-STX CPU : AMD Ryzen 5600G BIOS chip : Winbond W25Q128.w "AMD fTPM switch" within BIOS: Disabled Programmer used : CH341a /w USB interface
Have you tried using AMD's internal flasher to read the chip? What is the full command you used to run flashrom, and what was the error?
I'm a bit confused because you are looking at Bus Pirates, but list a CH341a w/ USB as the programmer used, which is also a fine external programmer. Does that mobo have one onboard?
