    S25FS256SAGBHI210 quad mode not working as expected

    sumuc_4051431

      I am using nrf52840 to interface with s25FS256 memory. I have been able to get it working in standard SPI mode, read and write works perfectly fine.

      I am trying to use Quad I/O mode. I am setting quad bit in CR1V to 1 but i am not setting QPI mode in CR2V as nrf qspi driver does not support QPI mode.

      With CR1V quad bit set to 1, the write seems to succeed, but when i read back the contents do not match. I get back mostly F's and D's. Any idea what i might be missing?
