Hi,

I’m trying to utilize IMU and seems there are deep dark magic issues. Can anyone help please ? I have updated/upgraded cape there is 0.3.4 version.

debian@beaglebone:~$ sudo rc_test_dmp -s 50 -m -g -t -a

the errors you are seeing is because the pins are not setup
pins get setup by using an overlay at boot time

verify the overlay you require is being loaded in /boot/uEnv.txt

as of any 4.x kernel everything must be loaded at boot time from that file

the cape manager is not used
