Fatal error

[Saira]

Hi

i am getting Fatal error while uploading code in my nRF52823 plz find attachment which i enclosed.

and showing break point at     NRF_BREAKPOINT_COND; plz tell me what should i do ?

Thank you

As Turbo J said, please check that you are using the correct baudrate on your UART terminal. I see from the youtube video that you use 115200 on your UART (arduino IDE) terminal. Is that also what you use in your Segger Embedded Studio project?

Check the function uart_init() in main.c.

static void uart_init(void)
{
    uint32_t                     err_code;
    app_uart_comm_params_t const comm_params =
    {
        .rx_pin_no    = RX_PIN_NUMBER,
        .tx_pin_no    = TX_PIN_NUMBER,
        .rts_pin_no   = RTS_PIN_NUMBER,
        .cts_pin_no   = CTS_PIN_NUMBER,
        .flow_control = APP_UART_FLOW_CONTROL_DISABLED,
        .use_parity   = false,
#if defined (UART_PRESENT)
        .baud_rate    = NRF_UART_BAUDRATE_115200
#else
        .baud_rate    = NRF_UARTE_BAUDRATE_115200
#endif
    };

    APP_UART_FIFO_INIT(&comm_params,
                       UART_RX_BUF_SIZE,
                       UART_TX_BUF_SIZE,
                       uart_event_handle,
                       APP_IRQ_PRIORITY_LOWEST,
                       err_code);
    APP_ERROR_CHECK(err_code);
}

What do you use as the .baud_rate?

The error did not show up in the video. What did you change so that this issue occured?

[Saira]

yes I am using the same baud rate 

and I am using terminal software to receive the data and also for transmit 
plz see in the screenshot

and this nRF UART APP which I am using to send the data

Thank you

This is the path

G:\EMBEDDEDBMY\nRF52832 new version\nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_uart\pca10040\s132\ses

ok I used 16th version in my project 

in which what I changed I wrote DEBUG in preprocessor definition (in COMMON mode)

After that, I changed NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED to 0 in sdk_config.h.

and last and finally i commented //APP_ERROR_HANDLER(p_event->data.error_communication);
after that 17th pin number led started blinking.
i connected via nRF UART APP to the BLE then LED stopped blinking.

But i am not able to receve on APP printf("\r\nUART started.\r\n");
and also not able to  transmit

Thank you
