Unable to blink LED via GPIO on Jetson Orin NX Dev Kit

[alexis23]

Hello JerryChang,

I continue to have the same issue with the GPIO pin, one think i noticed also is following this document:

Jetson_Orin_NX_Orin_Nano_Pin_Function_Names_Guide_DA-11434-001_v1.0.pdf

It tells me pin 211 is the GPIO09 that goes out to header pin 7, and Im following that document due to the response in this forum.

Orin Nx - Sysfs Pin Mapping for GPIO

Hello, I was trying to implement the SIM7600X 4G on the Orin NX using this wiki and I ran into an error invalid argument while executing this line: echo 200 > /sys/class/gpio/export I realized that this error could be due to me using a Jetson Orin NX instead of the Jetson Nano used in the wiki. The Mapping for GPIO on the Orin NX is different than the Jetson Nano. I was able to find the 40 pin Mapping of the Systs GPIO for Jetson Nano GPIO Header (NVIDIA Jetson Nano J41 Header Pinout - Jets…

So when I try gpioinfo, line 211 isnt there so I do gpioinfo gpiochip0 | grep PAC.06 and find it connected to line 144 and use that but still no change to the voltage on the pin.
