I'm trying to wire a Winbond W25Q128FV to my Rasberry Pi Model 1B so that I can dump the firmware. I'll be using an SOIC8 clip and probe cables.Here is what I'm thinking:Flash ----- rPiCS ----- CS0DO ----- MISOWP ----- ??GND ----- GNDVCC ----- 3V3HOLD ----- ??CLK ----- SCLKDI ----- MOSII've read that WP and HOLD/RESET should also be connected to 3V3, but there's only 2 3V3 pins on my pi?

firmware;memory;flash;memory dump
You don't need to use WP and HOLD at all. It will work without.You can try without first. Is write protect enabled?
