Hello, I am using pca10028 and sdk 12.2. I am trying to add app_uart_fifo.c file to my code. I have added the paths and also I have made changes in sdk_config.h. The changes I made in sdk_config.h are
// <e> APP_UART_ENABLED - app_uart - UART driver
//==========================================================
#ifndef APP_UART_ENABLED
#define APP_UART_ENABLED 1
#endif
#if APP_UART_ENABLED
// <o> APP_UART_DRIVER_INSTANCE - UART instance used
// <0=> 0
But I am getting error as below.
.\_build\nrf51422_xxac.axf: Error: L6218E: Undefined symbol app_fifo_flush (referred from app_uart_fifo.o).
.\_build\nrf51422_xxac.axf: Error: L6218E: Undefined symbol app_fifo_get (referred from app_uart_fifo.o).
