 As of this writing, the "official" way to build the Jetson Xavier NX kernel is to use a cross compiler on a Linux PC. This is an alternative which builds the kernel onboard the Jetson itself. These scripts will download the kernel source to the Jetson Xavier NX, and then compile the kernel and selected modules. The newly compiled kernel can then be installed. The kernel sources and build objects consume ~3GB.

 The copyImage.sh script copies the Image to the current device. If you are building the kernel on an external device, for example a SSD, you will probably want to copy the Image file over to the eMMC in the eMMC's /boot directory. The Jetson will usually try to boot from the eMMC before switching to a different device. Study the boot sequence of the Jetson to properly understand which Image file is being used.
