 As of this writing, the "official" way to build the Jetson Nano 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 Nano, and then compile the kernel and selected modules. The newly compiled kernel can then be installed. We recommend a SD card size of 32GB, 64GB preferred.

 The intended use of this repository is to help automate building known configurations of the kernel and build modules. You should use the kernel-4.9/scripts/config script to set the kernel configuration that you desire. See the 'rootOnUSB' repository on the JetsonHacksNano Github account for an example.
