![]() Or isn’t it?Īlso I can read/write other chips (like Winbond W25Q64BV) if I put them in a SOIC socket. I think the chip should be fine, since it’s unlikely that it was damaged by afuwin. The mainboard was running fine until the owner used afuwin to read the bios into a file, inserted a new microcode for his cpu with mmtool and tried to flash the resulting bios file back.Īfuwin erased the chip then the app crashed while trying to write it. So I have to work with either the JSPI1 pins or the test clip. Or does anyone have an idea what the problem could be here?Īny help is appreciated as it might keep me from going insaneĪlso: I can’t desolder the chip since it is in a bad spot with small resistors and plastic around it and I’m totally not equipped for such a precision soldering. Here is the description from the specification:Ĭould that be a problem since I can not see anything like 10V or similar on the CH341A programmer (even tho I can select the chip model manually, so it should be supported)? I’ve also checked the chip specifications and it says “WP#ACC” on pin 3. I’ve tried so many things already, it really drives me insane… ![]() I tried with cmos battery in and out, with power to the mainboard conntected (not turned on and turned on). I have totally stripped the mainboard from all components (cpu, ram, etc.). 1.13 and 1.18 seem to read the chip but 1.30 only says that it can not detect the chip. Still the CH341A Programmer software can not detect the chip (I’ve tried version 1.13, 1.18, 1.30). So from what I see, everything looks fine. The clip is aligned correctly (I’ve tested that every pin of the chip is connected to the correct pins on the CH341A and that there are no non-connected pins etc.). So I am now trying to flash a bios file onto the chip using my CH341A Programmer and a SOIC test clip. ![]() The chip can not be detected, reading goes to 100% and shows empty, writing give a time out. The connections should be correct according to pinouts I’ve found via Google. ![]() I have tried using the JSPI1 pins of the mainboard in combination with the CH341A but have not succeeded. I guess that’s what happens when the BIOS chip is empty? The board can be turned on (LEDs lighting up etc.) but obviously it does not display anything on screen or boot up. The Update erased the chip and then the PC shut off completely without flashing anything. I have a bricked Mainboard due to a bad Bios Update. ![]()
