To prep for building:

$ export MAKEFLAGS="-j4 -s PLATFORM_VARIANT=jetson"

Before you begin, ensure that you've setup network access, either with ethernet or wlan.

Setup timezone

sudo dpkg-reconfigure tzdata

Typically we use "US/Pacific-New"

Mount sdcard

Linux for Tegra (LT4) uses UBoot as its bootloader, replacing fastboot. In order to enable the full size USB port as 3.0, you can change the boot configuration file on the Jetson.

The boot configuration file is located here:

/boot/extlinux/extlinux.conf

There are several example configuration files in that directory which define how to boot from different devices.

The switch to change is:

#!/bin/sh
# Add some niceties for a new NVIDIA Jetson TK1 - LT 19.3
# Installs Chromium, git and aptitude
# Mark this file as executable in the permissions are of the properties dialog then
# $ sudo ./configureJetson.sh 

# Don't allow apt-get upgrade of xorg overwrite libglx.so
# May be fixed in future versions of LT4
sudo apt-mark hold xserver-xorg-core
