I am having an issue at the moment. I use freeRTOS with the AT91SAM7S and it works perfectly fine for my application. Problem is, I recently found that I need to use the SYS interrupt to the DBGU. The PIT, the system tick, is connected to the same interrupt! I located the interrupt handling function in port.c, BUT… Is it safe to implement DBGU-mask inside that fucntion to run parallell to the system tick interrupt!!! Any particular precautions recommended??
