Interfacing FAT file system into WinbondW25Q02 using SPI-nor driver

[Barsa]

Greetings,

I have been trying to integrate file system into Winbond W25Q02 NOR storage, Initially I tested the hardware by interfacing SPI communication between nrf 5340 and winbond and I was able to read JEDEC id, write characters into various pages and read back from them, so hardware is NOT the problem. Now I saw that zephyr allows us to integrate file system and there is a library called SPI nor, which is heavily inspired by Winbond. Before jumping into my storage for testing file system, I tested a "Mass" sample which I found in nordic SDK. it follows QSPI protocol, and I was able to mount the mx25r64 storage, which is already present inside nrf dk. Now when I use the same code, with modifications for communication (instead of QSPI, I need SPI),I get the error saying JEDEC id 00 00 00  does not match my given id in the overlay i.e ef 70 22. I just edited prj.config and overlay file in the mass sample for this purpose and I am really not sure if I need to make any changes on main.c or spi-nor.c driver for this. 

This is my overlay file

This is the link to winbond datasheet that I am using. Any help would be much appreciated!
