Forum Post: Interrupts not firing on BeagleBone Black with Starterware

I'm using a BeagleBone black with starterware, and I've gotten a few basic programs working. However, anything I do with interrupts fails. I've tried both the mcspiFlash example from the evmAM335X folder and the dmTimer example for the beaglebone, and in both, the interrupt never fires. Does anyone know what the problem is here?

Thanks.
