I difficult question, but I ask it anyway hoping that someone has the right answer.
I have a Winbond W25Q64FV and I need to program it in some way. I tried using the CH341a programmer with the related software, but the software has not the right chip in the library so I used the most similar one, the Winbond W24Q64. But after pressing read (the chip is already programmed so it’s not empty) and after some minute it still shows to me only FF. So I assume that the chip wasn’t read correctly. How can I read, but more importantly write, on this little piece of silicon?This is the schematic I’ve used (DO is MISO and DI is MOSI) without adding the resistor and obviusly not attaching the wires on a parallel port but on my CH341 programmer:
