Generate Pinmux File
Follow $JETPACK_ROOT/Xavier/Linux_for_Tegra/kernel/pinmux/t19x/README.txt to generate pinmux config file
You may see errors like below, please ignore it.

Copy Pinmux File
The generated pinmux file should be copied to $JETPACK_ROOT/Xavier/Linux_for_Tegra/bootloader/t186ref/BCT. Pinmux configure file name is defined here.
Flash Device
$ cd $JETPACK_ROOT/Xavier/Linux_for_Tegra/ $ sudo ./flash.sh jetson-xavier mmcblk0p1
Go Further
To check current pinmux setting or to manually update pinmux, take Update Pinmux Manually as a reference.
Notes
At present, pinmux configure file generated by Jetson AGX Xavier Pinmux is missing one line configuration like "pinmux.0x0c301000 = 0x00000500; # shutdown_n: rsvd0, ...".
