Hi,
I am working with the latest release for the Beagle Bone Black
and using the configuration commands found here
https://github.com/cdsteinkuehler/beaglebone-universal-io to configure
the PWM
Configuration seems to fail for every pin I have tried.
When I attempt to configure the PWM using config-pin -q P8.07
the response is P8_13 pinmux file not found!
Pin has no cape: P8_13
I have searched the group for others with similar issues and the solutions
have not worked for me.
Everything seems to be up to date and the uEnv.txt looks correct.
What am I missing?
Any help with this issue is greatly appreciated.
