Why don't i get continuity on pin 1 of the wson 8mb chip? to the soic chip all other pins have continuity and on jspi test point, but not pin 1 even with the chip off

Maybe the resistor at pin 1 has a problem.

Thank you i couldn't find that. do you have boardview?

badcapjer · 15/10/24

So far i'm testing on the donor board which has same no continuity on pin1 of the wson pad and i've only found connection to a resistor directly on the other side of the board which reads 4.7k

badcapjer · 15/10/24

Ok i mad a dumb assumption that cs pins all connected on spi. i see in the schematics that cs#0 of the wson has different jspi test points pins 8,9 which are fine. so i'm still stuck

I have built this file according to your original bios. If it doesn't load, you should check other problems. Maybe the problem is not in the bios.
