Hi, there is a function you can use to know the reset reason when the aplication reboots. 

/**@brief Function to read the reason for the last reset. The reason is printed in the console. */
void get_reset_reason(void)
{
	int result = hwinfo_get_reset_cause(&reset_cause);
    if (result == 0) // Success, reset_cause now contains the reset cause flags
	{
        LOG_ERR("RESET");

		if (reset_cause & RESET_PIN) LOG_DBG("Reset cause is: RESET_PIN\n"); // 0
		else if (reset_cause & RESET_SOFTWARE) LOG_DBG("Reset cause is: RESET_SOFTWARE\n"); // 1
		else if (reset_cause & RESET_BROWNOUT) LOG_DBG("Reset cause is: RESET_BROWNOUT\n"); // 2
		else if(reset_cause & RESET_POR) LOG_DBG("Reset cause is: RESET_POR\n"); // 3
		else if(reset_cause & RESET_WATCHDOG) LOG_DBG("Reset cause is: RESET_WATCHDOG\n"); // 4
		else if(reset_cause & RESET_DEBUG) LOG_DBG("Reset cause is: RESET_DEBUG\n"); // 5
    	else if(reset_cause & RESET_SECURITY) LOG_DBG("Reset cause is: RESET_SECURITY\n"); // 6
		else if(reset_cause & RESET_LOW_POWER_WAKE) LOG_DBG("Reset cause is: RESET_LOW_POWER_WAKE\n"); // 7
		else if(reset_cause & RESET_CPU_LOCKUP) LOG_DBG("Reset cause is: RESET_CPU_LOCKUP\n"); // 8
		else if(reset_cause & RESET_PARITY) LOG_DBG("Reset cause is: RESET_PARITY\n"); // 9
		else if(reset_cause & RESET_PLL) LOG_DBG("Reset cause is: RESET_PLL\n"); // 10
		else if(reset_cause & RESET_CLOCK) LOG_DBG("Reset cause is: RESET_CLOCK\n"); // 11
		else if(reset_cause & RESET_HARDWARE) LOG_DBG("Reset cause is: RESET_HARDWARE\n"); // 12
		else if(reset_cause & RESET_USER) LOG_DBG("Reset cause is: RESET_USER\n"); // 13
		else if (reset_cause & RESET_TEMPERATURE) LOG_DBG("Reset cause is: RESET_TEMPERATURE\n\n"); // 14
		else LOG_DBG("\n\n reset cause is: %d\n\n",reset_cause);

    	hwinfo_clear_reset_cause(); // Clear the hardware flags. In that way we see only the cause of last reset
    } else if (result == -ENOSYS) 
	{
		LOG_ERR("\n\n there is no implementation for the particular device.\n\n");
    } else 
	{
		LOG_ERR("\n\n negative value on driver specific errors\n\n");
    }
}

In my case the reset reason is  RESET_SOFTWARE. But I would like to have more info, how can I get it? I have a zigbee apliocation and I suspect the reset happes after I free the buffer. zb_buf_free(bufid); How can i debug this?

Best regards,
