If you want to use P8.20, you need to disable the eMMC. If you want to use P8.45 you need to disable the HDMI output (and someone needs to finish the missing cape-univ-hdmi). Note that you can access almost as many PRU0 pins (11 out, 10 in) without needing to disable either eMMC or HDMI. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
