I had this exact problem when I was trying to read my W530's chips with Raspberry Pi 3. Back then I ended up powering the motherboard using the Wake-on-Lan feature of Lenovo BIOS (and not connecting the VCC pin ofc), you can do the same and it should work but you have to be careful. But then I bought a ch341a programmer and it worked fine with W530. I'm not sure but maybe your ch341a doesn't have enough juice and that's why flashrom can't recognize chips reliably.

Hello,

I'm trying to put coreboot on a Lenovov Thinpad T530. I'm using a ch341a SPI flasher with the Pomona clip. I disassembled the mainboard to do a backup of the original BIOS image, but I think flashrom can not recognize the BIOS chips correctly. I tried to do the backup on both chips separately but they were BOTH recognized as a 8MB MX25L6405 Chip instead of a 4MB MX25L3206E and a 8MB MX25L3206E. Any suggestions?

I asked the same question on IRC, but I hate this shit IRC. By mistake I disconnected to the channel so I have no glue what was answered there. Maybe someone could be nice and send me the answeres on IRC.

Thanks
