I use BeagleBone Black with BeagleBoard.org 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
-bash: cd: /sys/devices/bone_capemgr: No such file or directory
How do I set pin mode ?
