error app: Fatal error ?

[RixtronixLAB]

Dear Members,

How can I find the cause of

<error> app: Fatal error ?

I can't see an error code ?

Is it possible hardware error because voltage surge ? Can capacitor rectify it ?

Thanks

I got this error :

<error> app: ERROR 0 [NRF_SUCCESS] at ..\..\..\..\..\..\..\..\components\librari

\libuarte\nrf_libuarte_async.c:230
                                           

 at: 0x000390A3
                                                              

rror> app: End of error report

How can I rectify it ? thanks

Hi,

Looking at the code line 230 has the APP_ERROR_CHECK_BOOL you see in this snippet:

    case NRF_LIBUARTE_DRV_EVT_RX_BUF_REQ:
    {
        if (p_libuarte->p_ctrl_blk->rx_halted)
        {
            break;
        }

        if (rx_buffer_schedule(p_libuarte) == false)
        {
            if (p_libuarte->p_ctrl_blk->hwfc)
            {
                p_libuarte->p_ctrl_blk->rx_halted = true;
            }
            else
            {
                NRF_LOG_ERROR("(evt) Failed to allocate buffer for RX.");
                APP_ERROR_CHECK_BOOL(false);
            }
        }
        break;

So it seems like you are not handling incoming data fast enough in your application. I suggest you either try to handle incoming data faster, or change the buffer sizes which you configure where you use NRF_CLI_LIBUARTE_DEF().

I have uint8_t        rxBuffer[256];

for libuarte GPS , I try reducing the size but still got the same error, any ideas ?,

How can I handle incoming data faster ? it's connected at 9600 baud, is it too slow ? thanks

Hi,

I do not see that the baud rate is relevant here. Did you try to increase the buffer? There is also a thread here, which may be relevant.

[RixtronixLAB]

do you think 1024 for RxBuffer ?

[Einar Thorsrud]

I am not sure, that depends on the root cause of this issue. Which SDK version are you using?
