MPLAB X DSPIC FREERTOS CRASHES

Posted by albanana on September 2, 2014

hello i wrote this program but i does not work, and the dspic crashes and resets periodically i use a logic analyzer for watching the CLOCKOUT and GPIO, and the watchdog is disabled

the program counter never goes to the Blink task but the timer 1 interrupt handler runs

did i make a mistake ? plz help!!!

THANKS :) sorry for the bad formatting

crashes and resets periodically

That makes it sound like the tasks starts running, but crashes/resets after a while.

the program counter never goes to the Blink task

That makes it sound like the task never starts running at all.

So I am confused as to how far you get in your application before the problem occurs. However, do you have the MPLABDSPICPORT symbol defined in your build options to tell the pre-processor to use the dsPIC version of the code rather than the PIC24 version?

Regards.

okay my mistake i declared #define MPLABDSPICPORT on top of FreeRTOSConfig.h and all works fine now. wrong assembly code caused exception and crash at switching context time.

problem solved THANKS
