nrf52840-read data

Hello forum ,

                   In here i will upload my project in zip where i m using w25q64 flash -nrf52840 .i m trying to read data of qspi flash read write and read for an two byte(trying for qspi write and read) .here my pins are P0.19 - clk;p0.16 -chqspi_try.zipip select ;P0.14 for MOSI(IO0);P0.23 for miso(IO1);P0.13 for flash hold and p1.15 - flash write protect ;i have alread add screenshot of output terminal ...pls go through it

  • i will upload the file that is default .dts file in before i musing w25q64 in .dts file used MX25r64

  • the above txt file is the default dts file in version qspi zephyr v 2.7.0 using MX25R64

  • Hi,

    I used your project but it does not build on my end. Can you share exactly which files or project I should use and how I shold build it? (please also check if you have any modifications in other SDK that is needed, and if so, share those as well)

  • now i can able to write and read in flash ......thank yu sir  ....
