PCA100040 uart example gets stuck

[Sampo]

Hello,

A stupid newbie question: APP_UART_FIFO_INIT seems to get stuck while trying to run example code.

Only modification I have made is the usage of SEGGER_RTT for debug. Does that mess up the uart somehow?

Best regards, Sampo

Hello Joakim,

Sorry to have this so broadly defined. I'm using nRF5_SDK_14.0.0, and I'm using the examples/peripheral/uart The ble_app_uart example works like charm, but not the uart example for connecting serial devices to the PCA100040 board. I can compile the example, flash it, run it, and it seems to run until it calls the macro APP_UART_FIFO_INIT. I did remove the RTT debug code and just used LEDs for testing. So with the code:

bsp_board_led_on(2);
APP_UART_FIFO_INIT(&comm_params,
                     UART_RX_BUF_SIZE,
                     UART_TX_BUF_SIZE,
                     uart_error_handle,
                     APP_IRQ_PRIORITY_LOWEST,
                     err_code);

bsp_board_led_on(1);

The second led newer gets lit up...
