Can not using debug (NRF_LOG_INFO) when using reading large data via UARTE

user112827

Hi,
I'm developing an application using UARTE to reading response from Module Sim. The content response from Module Sim has 495 characters.
When I debug, I only read some information I logged before and after that Segger will be crashed
Here is my uarte init

NRF_LIBUARTE_ASYNC_DEFINE(libuarte1, 0, 1, 2, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 1000, 3);
// using app timer for this uarte
NRF_LIBUARTE_ASYNC_DEFINE(libuarte2, 1, 2, NRF_LIBUARTE_PERIPHERAL_NOT_USED, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 1000, 3);



static void uarte1_init(void) {
uint32_t err_code;
nrf_libuarte_async_config_t nrf_libuarte_async_config = {
.tx_pin = TX_PIN_NUMBER1,
.rx_pin = RX_PIN_NUMBER1,
.baudrate = NRF_UARTE_BAUDRATE_115200,
.parity = NRF_UARTE_PARITY_EXCLUDED,
.hwfc = NRF_UARTE_HWFC_DISABLED,
.timeout_us = 100,
.int_prio = APP_IRQ_PRIORITY_LOW_MID};

err_code = nrf_libuarte_async_init(&libuarte1, &nrf_libuarte_async_config, uart_event_handler_1, (void *)&libuarte1);
APP_ERROR_CHECK(err_code);
nrf_libuarte_async_enable(&libuarte1);
}



static void uarte2_init(void) {
uint32_t err_code;
nrf_libuarte_async_config_t nrf_libuarte_async_config2 = {
.tx_pin = TX_PIN_NUMBER2,
.rx_pin = RX_PIN_NUMBER2,
.baudrate = NRF_UARTE_BAUDRATE_115200,
.parity = NRF_UARTE_PARITY_EXCLUDED,
.hwfc = NRF_UARTE_HWFC_DISABLED,
.timeout_us = 100,
.int_prio = APP_IRQ_PRIORITY_LOW_MID};

err_code = nrf_libuarte_async_init(&libuarte2, &nrf_libuarte_async_config2, uart_event_handler_2, (void *)&libuarte2);
APP_ERROR_CHECK(err_code);
nrf_libuarte_async_enable(&libuarte2);
}

    Not sure what you mean "Segger will be crashed"?
    Is it a hardfault or just hung without doing anything? 

    Have you started your application in debugger mode and run it for a while, pause and see what context of code the chip is executing?

    Hi, I'm using 2 libuartes to communicate with module sim and gps
    I'm using debug (NRF_LOG_INFO) to log contents I want to show. Debug Terminal showed correctly the content but for a while it stop at random line I used NRF_LOG_INFO and do nothing.
    For example I have an piece of code (I suppose it's easy to understand, because my code is quite complicated.)

    int main(){
NRF_LOG_INFO("init example");
for(;;){
NRF_LOG_INFO("data from sim");
NRF_LOG_INFO("data from GPS");
}
}



    Here is my debug terminal
    init example
data from sim
data from GPS

data from sim
data from GPS

data from sim
data from GPS

data from sim
data from GPS

data from sim


    As usual, it will have to continue to print. "data from GPS", but It stop at "data from sim" and do nothing.
    I use uart terminal as well (Hercules) and my data is still send and receive, but my debug terminal stop show like at initialize steps after reset

    This issue occurs when my nRF use libuarte1 to receive file http response from module sim (475 characters).

    My debug terminal is still running but nothing else occur,
