I'm using the PocketBeagle, and just installed the latest Debian image.  
Now, my script that sets I/O pins does not work.  I have already worked 
through the name change where, for example, P1_6 is now P1_06, but other 
config options such as in, out, hi, and low do not work.  Nor does 
config-pin display the status of the pin.

For example:

debian@beaglebone:~$ config-pin -q P2_33
Current mode for P2_33 is:     gpio

 

debian@beaglebone:~$ config-pin P2_33 lo
ERROR: write() to /sys/devices/platform/ocp/ocp:P2_33_pinmux/state failed, 
No such device


Contrary to the error, ocp:P2_33_pinmux/state does exist, but it must not 
like the value.  I find a lot of things that used to work no longer work.  
What has changed, and what do I do about it?
