I want to configure NVIDIA Jetson AGX Xavier GPIO pin number 22.
I have taken the code from this link GitHub - gaosiy/JetsonXavierGPIO
For modifying the GPIO pin number 22 i have modified the .cpp file as below:
jetsonXavierGPIONumber LEDControlPin = gpio417; gpioExport(LEDControlPin); gpioSetDirection(LEDControlPin,outputPin); /* To control pin high or low */ gpioSetValue(LEDControlPin, on); //Pull high gpioSetValue(LEDControlPin, off); //Pull low
After building when i try to execute the code then i am getting the below error:
gpioSetDirection unable to open gpio417: Permission denied
filedescriptor 3 Setting the LED on
gpioSetValue unable to open gpio417: Permission denied
I am also getting only 1.6 V on pin 22 instead of 3.3V while running this application.
Any kind of help to solve this problem will be highly appreciated.
