I am using FRDM-KW36 module. I want to use the SPI1 for my Flash memory. If I use the normal code than able to communicate with Flash memory using SPI1. But if I use the BLE code and implement the SPI1 then not able to communicate with flash memory.


I have imported the Wireless UART example code from SDK(ver: 2.2.1) and than enable the pins PTA16, PTA17, PTA18, PTA19 for SPI1.

I have connected Flash memory with this pins. Also commented the PTA16 pin to work as GPIO from Board_InitLEDs() and Board_InitRGB() functions. But not able to communicate.


Please help that how can I configure the SPI1 in BLE code and able to communicate with my Flash memory.


Thank You.
