Hi,

I’m a user of FreeRTOS with PIC24F and dsPIC33F.  
I’m starting a project in which I would like to use FreeRTOS with a dsPIC33E but I’m facing some trouble.  
Because of the instruction

```
{
   	*pxTopOfStack = PSVPAG;
}

```

in port.c file, I can’t compile a simple 1 task program that only blinks a LED.  
I’m using MPLAB C30 v3.30c compiler and the header file for this microprocessor doesn’t define PSVPAG.

What should I do to get FreeRTOS working with this microprocessor?

Thanks,  
Bruno Antunes

tlafleur,

Thanks for your suggestion.  
I think that it solved my problem. At least it compiles. I’ll have to test it.
