I find a lot of things that used to work no longer work.
What has changed,
config-pin got replaced by a compiled version, which i personally find
inferior compared to the older shell script one.
and what do I do about it?
i went back to the shell script config-pin,
available here: GitHub - cdsteinkuehler/beaglebone-universal-io: Device tree overlay and support scripts for using most available hardware I/O on the BeagleBone without editing dts files or rebuilding the kernel
