After LT4 21.3 Flash Setup – NVIDIA Jetson TK1

Some enhancements for desktop use

After installing the L4T on the Jetson TK1, changing a few settings for desktop use.

After flashing a Jetson with stock LT4 21.3 (See Jetpack 1.1 Installation), there are some setup tweaks that make the system more suitable for desktop use. Looky here:

The scripts have been placed in a repository on Github: https://github.com/jetsonhacks/postFlash.

Installation

The above video was shot immediately after the Jetson was flashed.
Open a Terminal and execute the following:

$ sudo apt-get install git
$ git clone -b JetsonTK1-L4T-21.3 https://github.com/jetsonhacks/postFlash.git
$ cd postFlash
$ ./configureSystem.sh

After installation, reboot the system for the changes to take effect.

Changes and Addtions

Chromium is installed as a browser. Firefox has issues downloading .zip files, so Chromium is a good alternative. Two other applications are also installed, aptitude and git.

USB 3.0 is enabled. The default is USB 2.0, /boot/extlinux/extlinux.conf must be modified to enable USB 3.0.

Two scripts are installed in /usr/local/bin. To conserve power, by default the Jetson suspends power to the USB ports when they are not in use. In a desktop environment, this can lead to issues with devices such as cameras and webcams. The first script disables USB autosuspend.

Also to conserve power, the Jetson manipulates the CPU cores and GPU clock speeds. The second script sets everything up for maximum performance.

Note: These changes will add about 0.5W of extra power draw.

The Jetson feels much more stable as a desktop environment after making these changes. Enjoy!

Note

You may find it more convenient to store the postFlash repository on a USB drive or SSD that is then plugged into the Jetson, so that it is simply a matter of running the configure script from local storage.
