config-pin errors

[Luke Stras]

I am feeling like an idiot here — this used to work a few months back, but I haven’t touched it in a while, and have done some system updates in the meanwhile.

I can’t seem to get config-pin to do anything useful for me:

debian@beaglebone:~$ sudo config-pin P9-23 lo
[sudo] password for debian:
P9_23 pinmux file not found!
WARNING: GPIO pin not exported, cannot set direction or value!

debian@beaglebone:~$ uname -r

debian@beaglebone:~$ cat /etc/dogtag

What am I missing?

Thanks!

This ^ disables cape universal...

PS the cape universal already contains a spidev node, you just need to use config-pin to much the spi pins..

Ah, I didin’t know that. It’s an artifact from an earlier project — removing it fixes the problem.

Thanks!
