Just wanted to inform you of an error as I ran this on a Odroid C2.

#!/usr/bin/python3

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

for i in range(0,28):
GPIO.setup(i, GPIO.OUT)
GPIO.output(i, GPIO.LOW)

dev@odroid:~$ sudo ./a.py Segmentation fault

Given the ff. test code
$ cat test-gpio.py

import RPi.GPIO as GPIO
PIN = 11
GPIO.setmode(GPIO.BOARD)
GPIO.setup(PIN, GPIO.IN)
def test(channel):
  pass

GPIO.add_event_detect(11, GPIO.BOTH, test)

Results in

Traceback (most recent call last):
  File "test-gpio.py", line 8, in <module>
    GPIO.add_event_detect(11, GPIO.BOTH, test)
RuntimeError: Failed to add edge detection  

strace shows driver access

openat(AT_FDCWD, "/sys/class/aml_gpio/export", O_WRONLY) = -1 ENOENT (No such file or directory)

but actual is

Current workaround for me was to override odroid_found to 0

Joshua,

I left this message in the forum but will copy it here with hopes that you may see it in one place or the other: https://forum.odroid.com/viewtopic.php?f=97&t=30577&p=287227#p287227

Pleas see the the terminal output below: (Note that I deleted most of the 'error' lines because they were repetitive)

Thank you for your consideration, please let me know if I can provide other information that may be useful.

Hello as mentioned, I get following error:

dietpi@DietPi:~/RPi.GPIO-Odroid$ sudo python3 setup.py clean --all
running clean
'build/lib.linux-aarch64-cpython-39' does not exist -- can't clean it

Hello, I'm trying to use RPi.GPIO on odroid xu4.

I tried to set pin 5 (in BCM) as interrupt request pin, with a code
GPIO.add_event_detect(5, GPIO.RISING, callback=self.handleInterrupt)

but occured an Error
RuntimeError: Failed to add edge detection

I read the README.txt,

Note that the current release does not support SPI, I2C, hardware PWM or serial functionality on the RPi yet.

Did the Error occur because RPi.GPIO-odroid don't have this feature?

Hi,
Root cause is that /proc/cpuinfo does not contain any Hardkernel specific info, I tried to hack it but I get a segmentation fault.
This is what /proc/cpuinfo looks like:
`processor : 0

The library is not working with N2. Is there a way?

Hello, on C2 I received an error as below:

root@DietPi:~/RPi.GPIO-Odroid/test# sudo python test.py
Traceback (most recent call last):
File "test.py", line 38, in
import RPi.GPIO as GPIO
ImportError: No module named RPi.GPIO

I screwed up something?
