Based on Updating the Bootloader Pinmux the following FAILED. I was testing so I redirected output to see what was going to be created, fat chance.

kernel/pinmux/t186$ python pinmux-dts2cfg.py --pinmux addr_info.txt gpio_addr_info.txt por_val.txt --mandatory_pinmux_file mandatory_pinmux.txt \

hello terrysu50z,

may I know how you generate those dtsi files, also, are you execute the conversion within JetPack-4.5?
please share the detail steps for reference,
thanks

the dsti files are missing from the “kernel/pinmux/t186” dir, that is the problem. I am following the documentation in the title.

hello terrysu50z,

you’ll need to use pinmux spreadsheets for generating dtsi files for the usage.
