Hi

I have a strange problem. I have created an queue.

I post on the queue every 1 sec with task 1 using:  
xQueueSend(g\_xRXEvent, (void\*)&nAll, ( portTickType ) 10);  
The function do succeed every time.

In task 2 I try to receive the queue message using the xQueueReceive  
while(TRUE)  
{  
if(pdTRUE == xQueueReceive (g\_xRXEvent, &nRXBufferIndex, portMAX\_DELAY))  
{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; …. Do stuff

The xQueueReceive never returns?  
When the scheduler is started, the xQueueReceive do return in task 2 the first time, but that is before anything is send to the queue by task 1.?

The two task have the same priority  
I’m running 7.1.0 on a LPC2478

I may add, that other queue seems to work. I have a UART isr using xQueueSendFromISR that is working.
