I am trying to program the bios chip with the ch341a but I can't erase it successful with what software I tried. even with yours. Please could you give me any advice? Thanks in advance.
are you using a voltage adapter? If not, it might be the flash chip's overvoltage protection that disables erase. IIRC, the MX25U parts are 1.8V.
However, the addresses in the various attempts flashrom made are increasing. So it seems it either succeeded randomly or reading (verification what was erased) is unreliable. How does your overall setup look like? Is the flash chip in the programmer's/adapter's socket?
