Program getting stuck on nrf_log_frontend_dequeue

[morpho]

In my application, the moment a callback is invoked inside the UART driver (which I wrote), I see the execution getting stuck on the following which resides inside nrf_log_frontend.c.

while (p_backend)
        {
            nrf_log_backend_flush(p_backend);
            p_backend = p_backend->p_cb->p_next;
        }
        NRF_LOG_WARNING("Backends flushed");

The callback is invoked here inside uart.cpp

if (dataRxd == '\r')
	  {
	      
	      pInstance->uartCallback(pFifoRx);
	  }

Hi,

Can you post the call stack when this issue occurs? Are you seeing any errors/hardfaults?

Best regards,
Jørgen

any luck?

Is it main.c or main.cpp that is used in your project?

I cannot see any calls to any NRF_LOG functions from the UART0 interrupt handler in your project, are you sure this is where the error occurs?

Can you provide instructions and/or a project that can be used to reproduce this issue on a nRF52840 DK?

This ticket may also be of interest.
