sudo ./flash.sh -r -k kernel-dtb jetson-xavier mmcblk0p1/
/


Once the dtb file is successfully updated, configure your Xavier's Ubuntu installation progress (language, keyboard type, location, username & password etc.).


After the previous step, you have to update kernel image file. Then copy "Image" file that attached end of the post to the MILBOARD-XV's /boot path. To do this attach ethernet cable and find your ip address on MILBOARD-XV's Desktop using ifconfig command.



Copy "Image" file over ssh to /home/nvidia path then move that file to /boot folder. After this step reboot your NVIDIA Jetson Xavier.



To avoid kernel update with "apt upgrade" or "apt-get upgrade" commands, please follow this guide on the Jetson module.


Finally, complete the SDK Manager installation progress. Type username & password and click "Install".
