I want to control the GPIO.09 on my Orin nano dev-kit.
I use SDK-Manager to flash to LT4 “R36 (release), REVISION: 3.0”.
01.When I use gpioinfo command to query GPIO9, it shows
, and the measured voltage is 0.
02.Then I use gpioset to pull high,
it shows
But the measured voltage is still 0.
You should run these commands with sudo permission.
I have run the sudo su before using the gpio commands.
The prompt is “#” (root mode), not $(user mode)
Oh sure, sorry I missed it.
Did you update the pinmux correctly so the pin is really an output pin?
Does the same pin work with JetPack 5 where you can directly control it with sysfs?
When I use L4T 35.4.1, I don’t need to do any modification.
Gpio command and sysfs are fine to control the GPIO pins(1,7,9,11) of 40 header pin.
Then please check this.
After seting the pinmux to output, it works by gpio command and sysfs,thanks.
