Missing NL for RTT ?

[JoWi]

I startet evaluation with nRF52840 and SES. 

I found the BSP Demo to crash (HardFault in Debug) after app_timer_init() , because of a NRF_LOG_INFO() inside, but Logging not initialised. After Re-arranging (as shown) everything worked with UART, but not RTT (no Output in the SES Debug Terminal, Flags set from UART to RTT).

Finally I found out, that a NL at te end of each NRF_LOG_INO is required (like ' NRF_LOG_INFO("BSP example started.\n"); '. 

 

/**
 * @brief Function for application main entry.
 */
int main(void)
{
    ret_code_t err_code;
    clock_initialization();

    APP_ERROR_CHECK(NRF_LOG_INIT(NULL));
    NRF_LOG_DEFAULT_BACKENDS_INIT();

    err_code = app_timer_init();
    APP_ERROR_CHECK(err_code);

    NRF_LOG_INFO("BSP example started.\n");
    bsp_configuration();

    while (true)
    {
        NRF_LOG_FLUSH();
        __SEV();
        __WFE();
        __WFE();
        // no implementation needed
    }
}

Hi, 

Nice catch for the hardfault in the debug mode of SDK 16.0 BSP example. I had reported it to the internal.

Finally I found out, that a NL at te end of each NRF_LOG_INO is required (like ' NRF_LOG_INFO("BSP example started.\n"); '. 

 Could you try to set NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED in sdk_config.h to 0? See this post for more information.
