Prepare Pinmux Files

• The required Pinmux files of Jetson Orin NX are different from Jetson Xavier NX

• The default file name for pinmux files is nx150. In other words, you will get the following files after exporting the Pinmux template Excel file.

  • Orin-nx150-gpio-default.dtsi

  • Orin-nx150-padvoltage-default.dtsi

  • Orin-nx150-pinmux.dtsi

• Then copy the files to different folder

# Put Orin-nx150-gpio-default.dtsi  into
cd $L4T/bootloader/

# Put Orin-nx150-padvoltage-default.dtsi, Orin-nx150-pinmux.dtsi into
cd $L4T/bootloader/t186ref/BCT/

Create Default Users

cd $L4T
sudo ./tools/l4t_create_default_user.sh -u nvidia -p nvidia -a
