I am having problem in configuring the N25Q256A flash from micron that comes with TWR-POS-K81. I have tried
1. Clearing bit 3 of the Nonvolatile Configuration Register.
2. Clearing bit 7 of the Enhanced Volatile configuration register.
But both the methods doesn't seem to work.
Reading both the registers after setting those bits again give me the old values. I set the WEL in the status reg before programming these two registers.
If any sample code to initialize the N25Q256A flash to QuadSPI will be greatly appreciated.
Thanks a lot
