Dear All,  
&nbsp;&nbsp;&nbsp;&nbsp; In FreeRTOS document on website proto of above function is given as  
portBASE\_TYPE xQueueSendFromISR(  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; xQueueHandle pxQueue,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; const void \*pvItemToQueue,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; portBASE\_TYPE \*pxHigherPriorityTaskWoken  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; );  
As per above I should pass ( &VariableName ) in third parameter to this function. But compiler is not acccepting it, giving error related to pointer. I gone through source, I found that in actual function that value is not accepted in pointer.  
Can anybody focus on this issue ?

Hi,  
I have the same problem, and “[http://www.freertos.org/upgrading.html](http://www.freertos.org/upgrading.html)” is no longer available.  
Could this issue had been resolved?

Chris

The link still works, watch out that the . at the end ISN’T part of the link. (you should go to [http://www.freertos.org/upgrading.html](http://www.freertos.org/upgrading.html) ).

It describes the change that needs to be made when changing from version 4 or earlier to version 5 or later.
