Hi ,the freeRTOS.h file supplied with their demo had the whole definition of the configASSERT commented out. Void vPortValidateInterruptPriority( void )Ĭonfig_ASSERT is defined in freeRTOS.h, is this a possible bug or do I need to change interrupt priorities ? to an invalid interrupt priority being missed.

ulCurrentInterrupt, so ulCurrentInterrupt getting corrupted cannot lead interrupted by a higher priority interrupt. However that should not matter as an interrupt can only itself be global – which makes vPortValidateInterruptPriority() non re-entrant. Limitations in the MikroC inline asm means ulCurrentInterrupt has to be I have searched and this snippet of port.c file (please ignore the quote before the hash) :.
