I'm trying to read W25Q128FV with a programmer: ch341 but it doesn't work.
I connected the chip with SOIC8 clips, I checked the connection many times, everything seems to be connected properly.
I use a laptop on which I use the program: AsProgrammer_1.4.1, but when I want to read/detect the chip, the program does not detect it.
I have not disconnected anything from the motherboard (components), the only thing removed is the CMOS battery.
Also, the computer is not connected to the PSU.
If needed I can provide pictures of my setup.

  • Did you measure resistances to make sure you can use a clip? You might be trying to power up the whole board using your programmer... check my guide here.
  • You might need to remove the conformal coating before making connections. Shoot some high-res pictures.
  • Did you mod the ch341 for 3.3v? Your chip is 3.3 by spec, while the ch341 (which model do you have?? photo?) usually gives you 5v
