BeagleBone Black Mode Selection

I use BeagleBone Black with Debian Buster IoT Image 2020-04-06 .

I read in a blog that if we have six pinmux then we increase GPIO speed.

So i check for command or file who shows pin modes:

and i found two files which shows pin modes and through the dtso can change it:

1)debian@beaglebone:~$ cd /sys/kernel/debug/omap_mux
-bash: cd: /sys/kernel/debug/omap_mux: No such file or directory

2)cd /sys/devices/bone_capemgr
-bash: cd: /sys/devices/bone_capemgr: No such file or directory

How do I set pin mode ?

How old was that blog? Otherwise, that’s a weird statement…

omap_mux was in pre device tree days…

This was in 3.8, 4.1, 4.4, and 4.14 based kernel’s… it’s long gone…

Use config-pin to individually set pin’s…

Thank You Config-pin is working from Unable to configure pins · Issue #76 · beagleboard/ · GitHub and then
GitHub - cdsteinkuehler/beaglebone-universal-io: Device tree overlay and support scripts for using most available hardware I/O on the BeagleBone without editing dts files or rebuilding the kernel.


Thanks Again.
