Hi, I have a jetson orin nano devkit. I’m on jetpack 6 with l4t 36.4. I’m trying to make some pins output pins and testing voltage with a multimeter running the python jetson-gpio pip package simple_output sample.
I’ve tried everything i’ve seen in the forums so far with no luck.
I downloaded pinmux spreadsheet for jetson orin
https://developer.nvidia.com/embedded/secure/jetson/agx_orin/jetson_agx_orin_pinmux_config_template.xlsm
I disabled 3.3V Tolerance and changed direction to bidrectional on the pins I want output. I generated device tree files, placed them in the appropriate directories, changed the reference name on pinmux.dtsi to make sure it references gpio.dtsi and updated the PINMUX env var in jetson-orin-nano-devkit.conf, i can see it being properly referenced during the flash process. It flashes successfully, but fails to boot. Below is the serial output when it boots.
flash command sudo ./flash.sh jetson-orin-nano-devkit mmcblk0p1 to SD card
dtsis attached
Does the template default to emmc somewhere i don’t see? Do I have the wrong pinmux template? is it only possible on orin nano devkit to use the 32.x L4T supported one?
