I’m having difficulty getting PWM working on my Beaglebone Black, recently flashed with balenaOS 2.29.2+rev3, kernel version 4.14.53+. The device overlays were supposedly added back in balenaOS v2.7.5+rev1.
The usual methods of enabling capes and such don’t seem to be working. I SSH’d into the host, and can’t find uEnv.txt (looked in /boot and /resin-boot), and “echo BB-PWM0 > /sys/devices/platform/bone_capemgr/slots” fails with “-sh: echo: write error: No such file or directory” (I can read the slots file just fine, though).
If it helps, my end goal is to extend the functionality of an existing Python app which is currently using the Adafruit BBIO library to control some LED drivers.
