Program enters hardfault after exiting from ZB_ZDO_SIGNAL_SKIP_STARTUP state

[anusha_14]

Hello Nordic support,

I am developing a Zigbee application based on FreeRTOS for a device with coordinator role. I was able to add the Zigbee stack and start the Zigbee task successfully. This is the code in the Zigbee task:

void ZigbeeTask(void * ptr)
{
    zb_ret_t       zb_err_code;
    /* Start Zigbee Stack. */
    zb_err_code = zboss_start_no_autostart();
    
    while (true)
    {
        zboss_main_loop_iteration();
        vTaskDelay(1);
    }
}

When I run the program, I am able to see that it initially enters ZB_ZDO_SIGNAL_PRODUCTION_CONFIG_READY state and then enters ZB_ZDO_SIGNAL_SKIP_STARTUP state. However, once it comes out of the ZB_ZDO_SIGNAL_SKIP_STARTUP  state, the program enters hardfault. On debugging, I can see that it successfully exits ZB_ZDO_SIGNAL_SKIP_STARTUP  state and enters zboss_main_loop_iteration function but not sure what happens next that causes the hardfault.

Could you please provide suggestion as to why the program crashes after ZB_ZDO_SIGNAL_SKIP_STARTUP state? Please let me know if you need additional details regarding my query.

Thanks,

Anusha

Hi Marte,

Thanks for this information.

Yes, this seems to be the probable reason because if I uncomment 'comm_status = bdb_start_top_level_commissioning(ZB_BDB_INITIALIZATION);' and set the function ZBal_erase_persistent_storage(true); with argument as true, then there is no hardfault because in this case, it does not need to load the data from NVRAM.

Regards,
