Hi KevinFFF,
Can you send a link to a topic (or to a document) that explains how configure pinmux?
Typically one would just use the PINMUX spreadsheet. You do have to enable macros in the spreadsheet software. After that it is pretty easy to see how it works. This is the download center’s search for “PINMUX” of the Nano:

(you can of course change filters or search terms)
Hi linuxdev,
I got the spreadsheet, made the changes to enable the SPI, ran the macro and got two .dtsi files. What would be the next step?
For Jetson Nano, you have to rebuild dtb and reflash the board to apply the change.
Please refer to NVIDIA Jetson Linux Developer Guide : Jetson Module Adaptation and Bring-Up | NVIDIA Docs for details.
