Thanks for the super fast reply, Charles! (And thanks for beaglebone-universal-io. It makes development on the BBB actually-approachable!)
I have access to the device now, so here is the real error message: (This is after a reboot, make, make install, and echoing the universal cape to the cape manager) # ./config-pin -a P9_42 ecapin bash: line 0: echo: write error: No such device Tracking it down a bit, I can produce the same message by doing what config-pin is trying to do: /sys/devices/ocp.3/P9_42_pinmux.47# echo ecapin > state bash: echo: write error: No such device So now my question is which magic word does "state" want to see? (Things like "gpio" and "pwm" work just fine there.) I had picked "ecapin" to try and match the style of the other names. Is there a premade identifier someplace that has to be used instead or is that free-form text that just has to match the line in dts? Is this something that needs to be added to the kernel before it will work? (I'm using 3.8.13-bone73.)
