QSPIF is giving error -0x4002

Hi There,

I am working on custom hardware based on PSoC 6 Wi-Fi BT Prototyping Kit (CY8CPROTO-062-4343W) and working on Mbed OS 5.15.4.

In our custom hardware, we have used the S25FL064L chip as a QSPI flash.

We have an issue in init using QSPIFBlockDevice. When I have enabled traces, I got a print “Init - Verification of SFDP signature and version failed”. Also, a strange thing is this issue comes when we do init → deinit ->init. So the first time the flash was successfully getting initialized, but after the deinit, when we do init again, it is having issues in SFDP header. I have printed the SFDP header for success as well as failure case, which will be in the log below.

Logs:
