Is there any QSPI flash other than MX25R64 that can be supported by NRF52840?

Yes, but you need to modify the device tree file of your board and nrf_qspi_nor.c according to the datasheet of your QSPI flash.

Hello,

What do I need to modify in the nrf_qspi_nor.c if you are using a different QSPI Flash?

Thanks,

Hi Oli,

1, Add a new jesd216_dw15_qer_type and change .dts files accordingly.

2, Modify nrf_qspi_nor.c and use the jesd216_dw15_qer_type value to separate differences between DK's MX flash with the flash driver you are using, in my case, QE bit and BP4 bit and 2 more status registers are different.
