Looks like I chose a bad pin for a good default demo. This is a different pin than used for the on-board LED. I tried to show both a PRU GPIO (via p9.30) and an OCP GPIO via the on-board LED. So, the LED still blinks because it is a different line that is controlled via the OCP GPIO rather than the PRU GPIO. > > Regards, > > -- > Robert Nelson > https://rcn-ee.com/ > > -- > For more options, visit http://beagleboard.org/discuss > --- > You received this message because you are subscribed to the Google Groups > "BeagleBoard" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/beagleboard/CAOCHtYg3zMOM3xtcd19zv-FMBG-idkaLzcsW84M7XXpT_bzgaw%40mail.gmail.com. > For more options, visit https://groups.google.com/d/optout. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
