adding SPI to ble_app_uart

im using Feather EVM. im using the app_ble_uart . after i added SPI to the project i dont get any errors but the code does not run (goes to main) and when i press run it goes into hard fault.

the SPI is enabled. 

  • i have no need for physical uart pins, i only use it for the ble communication. i am trying to disable it with no success.call-stack is:
    app_error_fault_handler()
    app_error_handler_bare(uint32_t error_code = ?)
    uart_event_handle(app_uart_evt_t * p_event = ?)
    uart_event_handler(struct <Unnamed 41> * p_event = ?, void * p_context = ?)
    uart_evt_handler(nrfx_uart_event_t const * p_event = ?, void * p_context = ?)
    uarte_irq_handler(NRF_UARTE_Type * p_uarte = 0x40002000, uarte_control_block_t * p_cb = m_cb (0x20003DE0))
    <Exception frame>
    [nrfx_coredep_delay_us::delay_machine_code + 0]

  • This looks like it is caused by errors on the UART HW. Try commenting out/remove call to uart_init() in main, this is what initializes the UART peripheral. You will also have to remove calls to app_uart_put() in nus_data_handler(), as calling this when the app_uart library is not initialized will cause errors.

    i did it but now in nrf_drv_uart.h , im getting :

  • You must have made more changes than the ones I suggested to get those errors. Did you modify sdk_config.h or remove some includes/source files?

  • thank you. after clearing all the errors its working.
