You expect us to guess what's wrong from that??!

What testing / investigation / debugging have you done to find where it's going wrong ?

Have you verified that your code is actually doing what the Winbond documentation says it needs to?

Have you used a scope or analyser on the wires?

I sent the commands flow based on WINBOND data sheet for read and write,

after every instruction i read and print the status of the device ,In WFH dont have Scope Analyzer to debug.

I need any sample code of any other External flash module, it will helpful to my development.
