'NVIDIA Jetson Orin' refers to the following devices:
Jetson AGX Orin Series, Jetson Orin NX Series, Jetson Orin Nano Series
'NVIDIA Jetson' refers to the following devices:
Jetson AGX Xavier Series, Jetson Xavier NX Series, Jetson TX2 Series, Jetson TX1, Jetson Nano
'Jetson' refers to all NVIDIA Jetson devices.
The NVIDIA Jetson and NVIDIA Jetson Orin devices are embedded Linux devices featuring a GPU-accelerated processor (NVIDIA Tegra) targeted at edge AI applications. You can easily add a USB external microphone or camera - and it's fully supported by Edge Impulse. You'll be able to sample raw data, build models, and deploy trained machine learning models directly from the Edge Impulse Studio.
In addition to the NVIDIA Jetson and NVIDIA Jetson Orin devices we also recommend that you add a camera and/or a microphone. Most popular USB webcams work fine on the development board out of the box.
Powering your Jetson
Although powering your Jetson via USB is technically supported, some users report on forums that they have issues using USB power. If you have any issues such as the board resetting or becoming unresponsive, consider powering via the DC barrel connector. Don't forget to change the jumper! See your target's manual for more information.
An added bonus to powering via the DC barrel plug: you can carry out your first boot w/o an external monitor or keyboard.
For example:
For NVIDIA Jetson Orin:
When finished, you should have a bash prompt via the USB serial port, or using an external monitor and keyboard attached to the Jetson. You will also need to connect your Jetson to the internet via the Ethernet port (there is no WiFi on the Jetson). (After setting up the Jetson the first time via keyboard or the USB serial port, you can SSH in.)
Issue the following command to check:
The result should look similar to this:
To set this device up in Edge Impulse, run the following commands (from any folder). When prompted, enter the password you created for the user on your Jetson/Orin in step 1. The entire script takes a few minutes to run (using a fast microSD card).
For Jetson:
For Orin:
With all software set up, connect your camera or microphone to your Jetson (see 'Next steps' further on this page if you want to connect a different sensor), and run:
This will start a wizard which will ask you to log in, and choose an Edge Impulse project. If you want to switch projects run the command with --clean.
With everything set up you can now build your first machine learning model with these tutorials:
Choose the deployment target according to your device and JetPack version. See table below.
4.6.4
NVIDIA Jetson (JetPack 4.6.4)
Docker container (NVIDIA Jetson - JetPack 4.6.4)
5.1.2
NVIDIA Jetson Orin (JetPack 5.1.2)
Docker container (NVIDIA Jetson Orin - JetPack 5.1.2)
6.0
NVIDIA Jetson Orin (JetPack 6.0)
Docker container (NVIDIA Jetson Orin - JetPack 6.0)
To run your impulse locally, just connect to your Jetson again, and run:
If you have an image model then you can get a peek of what your device sees by being on the same network as your device, and finding the 'Want to see a feed of the camera and live classification in your browser' message in the console. Open the URL in a browser and both the camera feed and the classification are shown:
Using make -j without specifying job limits can overtax system resources, causing "OOM killed" errors, especially on resource-constrained devices this has been observed on many of our supported Linux based SBCs.
Avoid using make -j without limits. If you experience OOM errors, limit concurrent jobs. A safe practice is:
This sets the number of jobs to your machine's available cores, balancing performance and system load.
edge-impulse-linux reports "[Error: Input buffer contains unsupported image format]"
This is probably caused by a missing dependency on libjpeg. If you run:
The end of the output should show support for file import/export with libjpeg, like so:
If you don't see jpeg support as "yes", rerun the setup script and take note of any errors.
edge-impulse-linux reports "Failed to start device monitor!"
If you encounter this error, ensure that your entire home directory is owned by you (especially the .config folder):
By default, the Jetson enables a number of aggressive power saving features to disable and slow down hardware that is detected to be not in use. Experience indicates that sometimes the GPU cannot power up fast enough, nor stay on long enough, to enjoy best performance. You can run a script to enable maximum performance on your Jetson.
ONLY DO THIS IF YOU ARE POWERING YOUR JETSON FROM A DEDICATED POWER SUPPLY. DO NOT RUN THIS SCRIPT WHILE POWERING YOUR JETSON THROUGH USB.
Your Jetson device device can operate in different power modes, a set of power budgets with several predefined configurations CPU and GPU frequencies and number of cores online. To enable maximum performance:
Switch to a mode with the maximum power budget and/or frequencies.
Then set the clocks to maximum.
To determine the maximum mode for your device visit the Supported Modes and Power Efficiency section in Jetson Linux Developer Guide for your L4T.
To enable maximum performance, switch to mode ID 0 and set the maximum frequencies of the clocks as follows.
For NVIDIA Jetson Xavier NX use mode ID 8
Additionally, due to Jetson GPU internal architecture, running small models on it is less efficient than running larger models. E.g. the continuous gesture recognition model runs faster on Jetson CPU than on GPU with TensorRT acceleration.
According to our benchmarks, running vision models and larger keyword spotting models on GPU will result in faster inference, while smaller keyword spotting models and gesture recognition models (that also includes simple fully connected NN, that can be used for analyzing other time-series data) will perform better on CPU.
If you see an error similar to this when running Linux C++ SDK examples with GPU acceleration,
Follow NVIDIA's setup instructions found at depending on your hardware.

Note that you may need to update the UEFI firmware on the device when migrating to JetPack 6.0 from earlier JetPack versions. See for instructions on how to get JetPack 6.0 GA on your device.
For NVIDIA Jetson devices use SD Card image with . See also or .
That's all! Your device is now connected to Edge Impulse. To verify this, go to , and click Devices. The device will be listed here.

Looking to connect different sensors? Our lets you easily send data from any sensor and any programming language (with examples in Node.js, Python, Go and C++) into Edge Impulse.
This will automatically compile your model with full GPU and hardware acceleration, download the model to your Jetson, and then start classifying. Our has examples on how to integrate the model with your favourite programming language.
For example for :
For :
then please download and use the SD card image version for your target see . The error is likely caused by an incompatible version of NVidia's GPU libraries - or the absence of these libraries.
