Are these two lines a must?

I don't want to use CLI function, I just want the flash crashlog backend function, but "Backends flushed" message kept showing...

I found solution.

attach

UNUSED_RETURN_VALUE(NRF_LOG_PROCESS());
cli_process();

after log print.

Hmm, try increasing the

NRF_LOG_BACKEND_UART_TEMP_BUFFER_SIZE

and possibly

NRF_LOG_MSGPOOL_ELEMENT_SIZE

in sdk_config.h

Best regards

It is not working... I increase 16384 from 2048.

I guess it is related on Log queue. how can I increase LOG queue?

I increase some values of log in sdk_config.h file. but It doesn't work...

It could seem that you are queuing more packets than the logging backend is able to process.

Snippet from nrf_log_frontend_dequeue(void) in nrf_log_frontend.c

else
{
    //Could not allocate memobj - backends are not freeing them on time.
    nrf_log_backend_t const * p_backend = m_log_data.p_backend_head;
    //Flush all backends
    while (p_backend)
    {
        nrf_log_backend_flush(p_backend);
        p_backend = p_backend->p_cb->p_next;
    }
    NRF_LOG_WARNING("Backends flushed");
}

Could you try to increase the log buffer, i.e. increase

NRF_LOG_BUFSIZE

in sdk_config.h?
