I upgraded my BeagleBone Black image for Debian 8.2, 2015-11-12.

When trying to view which overlays are enabled:

*cd /sys/devices/bone_capemgr.**

I get the following error


*bash: cd: /sys/devices/bone_capemgr.*: No such file or directory*

This used to work out of the box on my older Debian image.

Can anyone explain why this may be?
I'm trying to get the PWM on P9_21 to work.

When I execute a python script using the Adafruit tutorial 
<https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/pwm>
:

import Adafruit_BBIO.PWM as PWM
import time

PWM.start("P9_22", 50, 1000, 0)
print "Waiting"
time.sleep(2)
print "Finished"
PWM.stop("P9_16")
PWM.cleanup()

I get the following error:

*IOError: [Errno 2] No such file or directory: '/slots'*

Thank you for your time.
