Hi @umer_s 

Can you provide us the exact sequence of commands that you are following?

Also, you can check our low level driver for parallel NOR flash which is available on this link - https://www.cypress.com/documentation/software-and-drivers/low-level-driver-nor-flash?source=search&.... You can consider using this driver in your application if you are facing difficulty in writing code.

Regards.
