Wait i'm finding a problem with one of the pins. might be problem with donor chip

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

no i see it's correct same on donor board, so i'm lost

I don't know. nothing's working. solder joints look ok. any other ideas?

Maybe the resistor at pin 1 has a problem.

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

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

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.

Thank you. appreciate it. it's behaving the same with these files. constant fan. occasional cycling
