<p>Hello<br> First, I will explain my state.<br> My host PC is Ubuntu 22.04, and I flash my AGX ORIN 32GB devkit using SDK Manager.<br> SDK version is Jetpack 6.0 (rev. 2) and I flash it to NVMe SSD which is installed to board.</p> <p>After all processes are finished, I try to control GPIO with VS CODE using the code below.</p> <blockquote> <p>import Jetson.GPIO as GPIO<br> import time<br> GPIO_PIN = 40<br> GPIO.setmode(GPIO.BOARD)<br> GPIO.setup(GPIO_PIN, GPIO.OUT, initial=GPIO.HIGH)<br> print(“Press CTRL+C when you want the LED to stop blinking”)<br> while True:<br> time.sleep(2)<br> GPIO.output(GPIO_PIN, GPIO.HIGH)<br> print(“ON”)<br> time.sleep(2)<br> GPIO.output(GPIO_PIN, GPIO.LOW)<br> print(“OFF”)</p> </blockquote> <hr> <p>I’ve experience that this code is work for several month ago.<br> (I think that time my Jetpack version is 5.x)<br> But now I can’t control GPIO with this code.</p> <p>So, I try to figure how to solve this problem.<br> And I found in this forum that GPIO CONTROL on AGX ORIN with JETPACK 6.0 is not possible without changing(update) device tree.</p> <p>Refer to [ <a
