Using GPIO on Jetson Orin Nano (board: J401)

Community

Hello everyone,
I’m trying to use the GPIO on my Jetson Orin Nano with the custom board J401. The jetson was flash following the procedure specify by seeedstudio. The jetpack installed is 6.0.

I followed this tutorial but the output on my multimeter is always 0, it doesn’t matter if the value is set to HIGH or LOW. I connected the ground from the multimeter (black) to the jetson ground pin (6) and the voltage (red) to GPIO12 ( Same ping used on the tutorial).

I have tried with different pins and nothing, I also have another jetson with jetpack 5.1.1 but it doesn’t work either.
Output from gpio kernel values:

Jetson with JP5.1.1
 gpio-433 (PN.01               |sysfs               ) out hi 

Jetson with JP6.0
gpio-492 (PAC.06              |gpioset             ) out hi

Also what I noticed sometimes without changing values on the GPIO the multimeter changes from 0 to 1.6v and then goes back to 0.0V

Thanks in advance for your help

Hello, did you manage to solve the issue? We encountered same situation.
Jetson Orin Nano 8Gb + J401 board, Jetapack version 6.0

We didn’t manage to fix it :S at the end we communicate through serial with an arduino to enable or disable the GPIO

OK, thanks for heads up!
