hey guys  
Id used freertos to create a couple tasks earlier and run it on pic32mx starter kit… It ran fine… When i run it on the mplab sim tool, context switch does not occur… Two processes a and b are present of the highest priority… Im incrementing a counter in each… Only one counter gets incremented… Im using the official pic32 port…

The PIC32 port was written some time ago.&nbsp; I know, at that time, it could not be simulated in the PIC32 simulator as the simulator did not simulate everything.&nbsp; As I say, that was some time ago, so I don’t know if this is still the case.

Regards.

I can confirm that it still doesnt support mpsim… works fine on the kit
