Subject: [beaglebone] Problem at running startup the BBB
To: BeagleBone <[email protected]>
Hello
When I run any script in cloud9( inside BBB) in automatic mode ( running at
startup), ie, at reboot or power on and off the unit and if I include the
command lines GPIO.setup("Px_xx",GPIO.IN) or GPIO.setup(Px_xx, GPIO.OUT)
inside of the script, it don't execute. However , when I run the same
scripts without this lines , they works well.
The BBB only running at startup when I make a code to turn on any of the
leds USR1,USR2, USR3, but if I include any other commands lines the program
stop. Also, when I run the same scripts in manual mode in cloud9 , all work
well.
I tested with several GPIO pins and the same always happens
Do you have some idea what happen?
Bellow , I show one short script :
import Adafruit_BBIO.GPIO as GPIO
import time
GPIO.setup("P9_16",GPIO.IN) # this line is the problem
GPIO.setup("USR3",GPIO.OUT)
while True:
GPIO.output("USR3",GPIO.HIGH)
time.sleep(2)
GPIO.output("USR3",GPIO.LOW)
time.sleep(2)
Additionally , bellow can you find the error code I get from cloud9
Your code is running at http://localhost.
Important: use os.getenv(PORT, 8080) as the port and os.getenv(IP, 0.0.0.0)
as the host in your scripts!
*Traceback (most recent call last):*
* File "/var/lib/cloud9/Telemetria/alarmaprueba3.py", line 5, in <module>*
* GPIO.setup("P9_16",GPIO.IN <http://GPIO.IN>)*
*ValueError: Set gpio direction failed, missing file or invalid
permissions.*
Thank you in advance
Hugo
