Add zigbee to an existing freeRTOS project with BLE.

[vilpih]

Hello

I'm trying to add zigbee to an existing freeRTOS project with BLE.
The approach so far is combining "Zigbee Multi Sensor with FreeRTOS Example" and "Adding dynamic multiprotocol Zigbee support to BLE examples"
During the "zboss_start_no_autostart()", the program asserts at "configASSERT( xTaskToNotify );"

    void vTaskGenericNotifyGiveFromISR( TaskHandle_t xTaskToNotify,
                                        UBaseType_t uxIndexToNotify,
                                        BaseType_t * pxHigherPriorityTaskWoken )
    {
        TCB_t * pxTCB;
        uint8_t ucOriginalNotifyState;
        UBaseType_t uxSavedInterruptStatus;

        configASSERT( xTaskToNotify );
        configASSERT( uxIndexToNotify < configTASK_NOTIFICATION_ARRAY_ENTRIES );

Any clues or ideas of how to get pass this?

Hi,

I do not see any references to vTaskGenericNotifyGiveFromISR in the Thread SDK nor in FreeRTOS API.

Where is it defined? what is the context it is called from? 

I need the context and some code snippets to understand more about the issue.

It's called somewhere inside zboss_start_no_autostart() which is a part of the zboss stack

void zigbee_main_task(void *pvParameter)
{
    zb_ret_t       zb_err_code;

    UNUSED_PARAMETER(pvParameter);

    NRF_LOG_INFO("The zigbee_main_task started.");

    /* Start Zigbee Stack. */
    zb_err_code = zboss_start_no_autostart();
    ZB_ERROR_CHECK(zb_err_code);

    while (true)
    {
        if (xSemaphoreTakeRecursive(m_zigbee_main_task_mutex, 5) == pdTRUE)
        {
            zboss_main_loop_iteration();
            UNUSED_RETURN_VALUE(xSemaphoreGiveRecursive(m_zigbee_main_task_mutex));
        }
        vTaskDelay(1);
    }
}

We do not have code for that, and sounds like that this function has been called from the context it is not supposed to be called from. Do you happen to have a call stack trace when this assert happens? 

[vilpih]

It's the function is from your example so I suppose it's correct infocenter.nordicsemi.com/.../zigbee_multi_sensor_freertos_example.html

Can you please attach your project here. I am not an expert in Zigbee but I have good experience in FreeRTOS related issues.

If I can reproduce this on the merged project you have, I might be able to debug the internals.
