SPI serial flash memory not working on digital pins

Hi,

I am using w25q16 serial flash spi memory with nrf52832. 

the flash memory is working fine with all analog input pins(2,3,4,5,28,29,30,31).

but due to the hardware designing point of view, I want to shift my ss, CLK, miso, and mosi pin to  5,6,7,8 respectively.

i checked that spi memory is not working on any digital pins. do digital pins support spi functions?

  • I suspect that pins 5-8 may be used for UART, for instance if you are using logging over UART, then those pins may be in use already. If you are using the nRF52-DK then you can flip the board over to see which pins are by default assigned to specific use for the DK.
