Leave the PRU input (P9.42B) alone. Export the other pin (P9.42) as GPIO and set it to drive high. Since the pins are wired together on the BBB, the PRU should see the input as '1'. Make sure you switch P9.42 back to input before hooking it to whatever signal source you're planning on using. -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
