I'm getting this error: main.c: In function 'Timer_A': main.c:150:28: error: MSP430 builtin functions only work inside interrupt handlers __bic_SR_register_on_exit(CPUOFF); // Clear CPUOFF bit from 0(SR) ^ makefile:23: recipe for target 'main.o' failed With this code: // TimerA interrupt __attribute__((__interrupt__(TIMERA0_VECTOR))) Timer_A (void) { iflag |= BIT0; // Set BIT0 flag __bic_SR_register_on_exit(CPUOFF); // Clear CPUOFF bit from 0(SR) } For some reason msp430-elf-gcc thinks my ISR isn't an ISR Any ideas? I emailed one of the red hat guys who submitted the GCC patch with the function that checks whether a function is an interrupt handler or not.
