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
Hi,
The JEDEC ID of w25q64 should be [ef 40 17], but I understand you found that. As you are able to read the ID other communication/read/write should also be possible. I do not have that exact flash to test with, but I have a w25q16 that I intended to test with some modifications, but I am not able to build your projcet. Can you share a project that builds in the SDK without any other modifications, or alternatively, also share any changes you have done to the SDK (perhaps device tree files) as well? Along with instructions on how to build and test?

i have already upload my project as qspi_try.zip in above kindly pls go through in above
i will upload the file that is default .dts file in before i musing w25q64 in .dts file used 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 ....
