Orin pinmux changes and gpio dtsi file

[andrew.mank]

I’m changing the Orin dev kit pinmux using the procedure here:
Jetson AGX Orin Platform Adaptation and Bring-Up — Jetson Linux
Developer Guide 34.1 documentation (nvidia.com)

The pinmux spreadsheet creates 3 dtsi files: 1.) pinmux, 2.) gpio, 3.) padvoltage. I see the padvoltage does not need to be copied into the flash directory, but the pinmux and gpio dtsi files do.

How does the gpio dtsi file get specified in the flash config files? I see the pinmux file is defined in p3701.conf.common as PINMUX_CONFIG=“tegra234-mb1-bct-pinmux-p3701-0000.dtsi”;. The gpio file specified is GPIOINT_CONFIG=“tegra234-mb1-bct-gpioint-p3701-0000.dts”;. This is a dts file rather than dtsi file though. Do I need to convert the gpio dtsi into a different format or does it get specified elsewhere?

It looks like the gpio dtsi file is included in the pinmux dtsi file. Correct me if I’m wrong there please.

hello andrew.mank,

please check developer guide for the steps to make pinmux changes.
for example, Changing the Pinmux.

Thanks @JerryChang . That leads to the same link I orignally posted. I think I found the answer. See my reply on Jan 24.
