I want to change the GPIO direction during boot stage in Orin NX? How to do that?
Now I am making changes in PINMUX sheet and generating dts files as per bring up guide and replacing it.
I can see the change takes place only after boot manager ie during the login process/linux kernel , but I want it to happen in UBoot/CBoot stage.
I want GPIO3_PCC.02 to be set as Input during boot. please help.
Earlier in AGX Xavier/NX we used .cfg files
Are you using the devkit or custom board for Orin NX?
What’s your Jetpack version in use?
Please refer to the following instruction to configure the pinmux spreadsheet and update the generated dtsi to your BSP package.
Jetson Orin NX and Nano Series — Generating the Pinmux dtsi Files
Unlike Xavier series, you don’t need to run python script to generate .cfg.
For Orin series, you just need to replace the original pinmux/gpio/padvoltage dtsi.
