Hi, everyone!
I’ve been spending a lot of time trying to enable GPIO pins on Jetson Orin Nano Super Developer Kit.
I know there is an issue with Jetpack 6.x (I’m currently using Jetpack 6.2) and GPIO pins. I’ve tried to make a custom pinmux configuration but gave up after creating the three .dts files because I couldn’t find the folders where I was supposed to copy them into.
Then, I decided to try and do it dynamically using busybox and devmem. I wanted to enable GPIO 07 so I did some research and found out the 32-bit address was 0x02434000.
I run:
sudo busybox devmem 0x0x02434000
and get:
0x00000400
I tried typing
busybox devmem 0x02430070 w 0x004
as suggested here: here and other write commands but keep getting the same output.
As I read in the docs, I am supposed to change bit 10 to 0 in order to set it up for GPIO, but I don’t really know how to do that.
I also tried typing this:
dmesg | grep gpiochip
and nothing appears on the screen.
I would be really grateful if someone could help me setting up my pinmux both dynamic or using pinmux configuration (as long as I don’t loose all my files).
Thank you.
