Hello, first time here. I got an issue.

I was trying to use PWM but an error showed.

Traceback (most recent call last):
  File "dc_motor.py", line 14, in <module>
    p = PWM.start(P_W_M, 50)
RuntimeError: Problem with the cape manager

This is the python file:

import Adafruit_BBIO.GPIO as GPIO
import Adafruit_BBIO.PWM as PWM

P_W_M = 'P9_42'
IN4 = 'P9_25'
IN3 = 'P9_27'

GPIO.setup(IN4, GPIO.OUT)
GPIO.setup(IN3, GPIO.OUT)
GPIO.output(IN4, GPIO.LOW)
GPIO.output(IN3, GPIO.LOW)
GPIO.setup(P_W_M, GPIO.OUT)

p = PWM.start(P_W_M, 50)

I did run:

sudo /opt/scripts/tools/version.sh
