When I load a .dtbo though my uEnv.txt file (ie, uboot_overlay_addr4=/lib/firmware/bone_eqep2b-00A0.dtbo ) I no longer have access to config-pin's ability to set up ANY pins. Is there some sort of exclusiveness built into the system such that if .dtbos are found, then you cannot manually configure pins after boot with the config-pin utility?
My system info: [root@beaglebone]> uname -a Linux beaglebone 4.4.91-ti-r133 #1 SMP Tue Oct 10 05:18:08 UTC 2017 armv7l GNU/Linux Thanks in advance!
