I bought a CH341A - its a USB2 3.3v/5.0v BIOS programmer with an 1.8v daughter board. Looks pretty much like this one: https://www.banggood.com/EEPROM-BIO...Adapter-For-24-25-Series-Flash-p-1332376.html I need to reprogram a board because the bios update failed and it does not have a rescue bios. The chip on this board is 1.8v according to the spec sheet, so I hook it all up and it tells me that it can't detect the chip. Thinking the actual IC is cooked, I order some new ones off ebay. Doesn't detect those either. I go back to the vendor saying that the 1.8v daughter board isn't working. My methodology: I tested a HD5870 BIOS on the 3.3v part and it worked perfectly. They send me another one: Same problem. Chip on the board doesn't detect, chips from ebay don't detect. Can anyone help me diagnose this? Is it 3 crook chips or two crook 1.8v daughter boards? I've done everything I can think of. Voltages are correct (theres a few online posts about them being screwwy).
