I tried to control a servo with my Beaglebone blue and get the following error:
root@beaglebone:/var/lib/cloud9# rc_test_servos -c1 -p1.0
ERROR in rc_adc_init, failed to open iio adc interface
: No such file or directory
Perhaps kernel or device tree is too old
ERROR: failed to run rc_adc_init()
rc_test_drivers gives me:

Any ideas how i can fix this?
I tried some newer kernels, but this didn’t fix the problem and even created new ones with pru-proc, i2c, spi.
Any tipps which kernels could work? “apt-cache search linux-image” gives me hundreds of options…

Any ideas?
Seems a little bit odd to have these expensive board that is special designed for robots, but can’t control a simple servo out of the box.

u-boot in the eMMC is blocking overlays from working properly..
