Doesn't work. For a second, all the voltages and everything appear

I am unable to write to the chip even though I can read and erase it. The software hangs up as soon as I try to program using both Neo and AS Programmer and on two different computers. Do you have any idea what could be happening?

The chip is GD25B256DYIGR, and I have the black Ch341 board with the 3.3 V Mod.

Thank you

Hi
how did you write the chip? I am having the same issue. thanks

I bought a different programmer that didn't need a mod. EZP2023 worked right away
