That's one of the audio pins. The fact that the pinmux files don't exist probably means it's not under control of the universal overlay and is still being used for audio. You need to tweak which universal overlay you're loading in u-boot and/or disable the audio overlay. There used to be a _bunch_ of different flavors of the universal overlay with various things enabled/disabled (eg: audio, hdmi, emmc). RCN has simplified all this but I'm not 100% sure what you do/don't need to setup in uEnv.txt (I'm traveling and don't have a "modern" BBB OS install handy to reference). -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
