Interfacing nRF52832 with External flash using SPI

[Mushtakh Shaikh]

Hi, 

I am trying to interface IS25LP064A  External Flash with nRF52832 using SPI. I want to get the device ID/ Manufacturer ID of the flash. I am able to get the same in Arduino but I am unable to get it in nRF52. I am using SPI  example from SDK_v_16.0.  Please help me with how can I configure the device and read the device Id. Any example will also help. Thanks..

The simplest may be to connect a logic analyzer trace and measure timing and serial data (command and data) using Arduino first. Then compare this with the logic analyzer trace when using the SPI example.

Best regards,
Kenneth

Thanks Kenneth for the reply but unfortunately I don't have  any logic analyzer with me. Now I am able to read device Id and Manufacturer Id.

Now I am trying to write the data into external flash and also I want to read it. 

I have implemented the functions but it seeems not working fine. Can u please help me with it
