Hello everyone, I have been trying to configure the GPIO Pin 1_31 on the Beaglebone Black to recieve input signals.
I have followed the following tutorials: - http://blog.machinekit.io/2013/06/black-is-white-is-grey.html - https://github.com/modmaker/BeBoPr/wiki/BeBoPr-goes-Black My specific steps were the following: - Enable Reset line on the Beglebone Black with the program mmc-utils(https://kernel.googlesource.com/pub/scm/linux/kernel/git/cjb/mmc-utils) executed on mmcblk0 as argument - Disable boot on the Beaglebone - Boot from SD-card - Changed uEnv.txt - Added gpio set 52 - Added mmc dev 1 - Added mmc rstn 1 - Disabled loading of the mmc and hdmi overlays - Set Pin 33 to mode 37 with a custom device tree overlay - Export the Pin for input mode Applying these steps results in the Input being high constantly even with no connected curcuit. Connecting a curcuit with an LED results in the LED glowing. Using the Pin as Output works fine. Using a pre-built device tree overlay results in the Pin constantly being low even if a current is applied. The curcuit used works with other none mmc allocated pins. I am grateful for any kind of feedback or tips Best Regards Sebastian -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
