updated config-pin?

[m...@yapatel.com]

Hi -

I just our project to 4.1. I made the mods necessary to the dts to account for the gpio changes/etc and can load the overlay. However, when I run 

config-pin P9.29 gpio

to set the pin modes and states, I am faced with:

bash: /sys/devices/platform/ocp/ocp*P9_29_pinmux/state: No such file or directory

Cannot write pinmux file: /sys/devices/platform/ocp/ocp*P9_29_pinmux/state

It looks like the structure of the ocp dirs has changed - so I assume this is expected. But where/how to set the state now is unclear to me. Is there a "newer" version of config-pin available?

debian@beaglebone:$ uname -r

4.1.10-ti-r24

debian@beaglebone:~/puggledriver/apps$ dtc --version

Version: DTC 1.4.1-g8e001df3

Pulled that repo, and used that config-pin script to try and I get the same errors again. I see the changes you made to the script, however those changes are still trying to write to /sys/devices/platform/ocp/ocp*P9_29_pinmux/state - but there is no "state" file in any of the P* directories. Did I forget a step?...

did you load the cape universal overlay?

4.1.10-ti-r24.... P9_29 works for me.

However, I get that error for P8_10.

config-pin P8.10 low

bash: /sys/devices/platform/ocp/ocp*P8_10_pinmux/state: No such file or directory

Cannot write pinmux file: /sys/devices/platform/ocp/ocp*P8_10_pinmux/state
