Locations of Files and PinMuxing

Hello,

As some of you know, I am working on an ArduCopter build on the BBBlue for now.

ā€¦

So, I am getting a zilch. The shell script I provide is simplistic and just calls echo to start the pruecapin_pu device which is located, or should be located here:

/sys/devices/platform/ocp/ocp:P8_15_pinmux/state

For some reason, on Linux beaglebone 5.4.106-ti-rt-r35 #1buster SMP PREEMPT_RT Thu Sep 16 19:07:29 UTC 2021 armv7l GNU/Linux , I cannot make echo make this file available.

P.S. Is this something new in the 5.4.x kernel or do I need to have something I am missing? I searched throughout the filesystem, the old fashion way, to get ideas on where this file, after calling echo , may be located. I am stuck.

Hello,

The above text is not located in the respective place b/c of it being listed in the descriptions of the .dts file, i.e. am335x-boneblue.dts.

Hello,

You are welcome.

P.S. I know I am needy in technology. I am spongy for now.
