Get Started with balenaCloud using Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME and Haskell
In this guide, we will help you get started with balenaCloud by:
- Setting up your Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME device and bringing it online on the balenaCloud dashboard.
- Deploying a Haskell hello-world project on the device.
- Developing the sample project: making changes and testing them on the device in real-time.
Once you've completed this getting started guide to balena, you'll be equipped with the fundamentals needed to continue developing your application using balenaCloud and be on the path to deploying fleets of devices to production. If you are looking for definitions of certain terms, refer to the glossary.
What you'll need
- The device: Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME. Checkout our supported devices list.
- A tool to flash the new operating system on to the device. We recommend Etcher.
- A way of connecting the device to the internet, either through wifi (if available) or ethernet cable.
- A method of reliably powering the device.
- A balenaCloud account.
- Install balena CLI to develop & manage your device on balenaCloud
Create a fleet
A fleet is a group of devices that share the same architecture and run the same code. Devices are added to fleets and can be moved between fleets at any time.
To create your first fleet, log into your balenaCloud dashboard and click the Create fleet button.
Enter a fleet name, select the Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME device type, choose the Starter fleet type, and click Create new fleet:
You'll then be redirected to the summary of the newly created fleet, where you can add your first Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME.
Add a device and download OS
balenaCloud builds a custom balenaOS image configured for Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME which allows the device to provision and join the new fleet you created automatically. Start by clicking Add device on the fleet summary. Your device type will be preselected here since you already chose it when creating the fleet. Other device types of the same architecture can also be picked to join the fleet.
Select an OS type of balenaOS, and you will see a list of available balenaOS versions with the latest preselected. Choose a Development version of the OS. The production OS does not facilitate the development workflow we'll be using. Find out more about the differences between Development and Production images.
Select the type of network connection you'll be using: Ethernet Only or Wifi + Ethernet. A network connection is required to allow the device to connect to balenaCloud. Selecting Wifi + Ethernet allows you to enter a Wifi SSID and Wifi Passphrase which is then built into the image.
Finally, click the Download balenaOS button. When the download completes, you should have a zipped image file with a name like
Next, we will flash the downloaded image onto the device. To do so, follow the following steps:
- Insert the USB key to the host machine.
- Write the balenaOS file you downloaded to the USB key. We recommend using Etcher.
- Wait for writing of balenaOS to complete.
- Remove the USB key from the host machine.
- Insert the freshly flashed USB key into the Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME.
- Warning! This will also completely erase internal storage medium, so please make a backup first.
- Insert a NVME drive in the carrier board and put the device in force recovery mode. Connect the USB-C port of the carrier board to the Host PC. RCM boot the balenaOS kernel following the Orin Nano Flashing steps.
- Wait for the Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME to finish flashing and shutdown. Please wait until power LED is off.
- Remove the USB key from the Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME.
- Remove recovery mode jumper and power up the Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME to boot the device.
When complete, after a minute or two the device should appear on your balenaCloud dashboard, and you should now be ready to deploy some code. If you are not able get the device to appear on the dashboard, then check out our troubleshooting guide for Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME or try our support channels.
Install the balena CLI
Now that a device online in your fleet, it's time to deploy some code. We will use the balena CLI for this. Follow the instructions below to install balenaCLI for the operating system available on your system.
- Download the CLI installer.
- Double click the downloaded file to run the installer and follow the installer's instructions.
- To run balena CLI commands, open a command prompt: Click on the Windows Start Menu, type PowerShell, and then click on Windows PowerShell.
- Download the standalone CLI.
Extract the contents of the zip file to any folder you choose, for example
/home/james. The extracted contents will include a
Add that folder (e.g.
/home/james/balena-cli) to the PATH environment variable. Check this StackOverflow post for instructions. Close and re-open the terminal window so that the changes to PATH can take effect.
For more detailed information, visit the detailed Linux installation instructions.
After balena CLI is installed, login to your balena account
balena login command on the terminal:
$ balena login _ _ | |__ __ _ | | ____ _ __ __ _ | '_ \ / _` || | / __ \| '_ \ / _` | | |_) | (_) || || ___/| | | || (_) | |_.__/ \__,_||_| \____/|_| |_| \__,_| Logging in to cloud.com ? How would you like to login? (Use arrow keys) ❯ Web authorization (recommended) Credentials Authentication token I don't have a balena account!
You will be asked to choose an authentication method, choose Web authorization which will bring up a web browser window that allows you to login to your balenaCloud account. Click the Authorize button, and head back to the terminal after the login successful message appears.
Create a release
After login, test the balena CLI by running the
balena fleets command, which should return information about the fleet you created in the previous step. Take a note of the
FLEET NAME as you'll need this in the next step to push the code to your device(s) in that fleet.
$ balena fleets ID FLEET NAME DEVICE TYPE ONLINE DEVICES DEVICE COUNT 98264 First-Fleet Nvidia Jetson Orin Nano 8GB (SD) Devkit NVME 0 0
A nice project to try is the balena-haskell-hello-world project. It's a Haskell web server that serves a static page on port 80. To get started, download the project as a zipped file from GitHub, unzip it and open a terminal in the root of the extracted project directory.
To create a release, use the
balena push First-Fleet command replacing
First-Fleet with the name of your fleet. Ensure you are working from the root of the extracted project directory.
$ balena push First-Fleet
This command pushes the code to the balena builders, where it will be compiled, built, turned into a release, and applied to every device in the fleet.
You'll know your code has been successfully compiled and built when our friendly unicorn mascot appears in your terminal:
[hello-world] Successfully built 51bd190f7530 [Info] Generating image deltas from release 8acfdc579f7cb0fe424d1b800588b6f5 (id: 2186018) [Success] Successfully generated image deltas [Info] Uploading images [Success] Successfully uploaded images [Info] Built on builder05 [Success] Release successfully created!

The release will then be downloaded and started by all the devices in the fleet. You can see the progress of the device code updates on the device dashboard:
After the download, you should now have a Haskell web server running on your device and see some logs on your dashboard.
To give your device a public URL, click the Public Device URL toggle on the device dashboard. Public device URL allow you to serve content from the device to the world easily without configuration as long as the server is running on port 80.
Follow the URL to view the welcome page with additional resources. Alternatively, you can point your browser to your device's local IP address to access the server running on your device. You can find the device's IP address on the device dashboard page. This is what you should be seeing.
Developing your project
Now, let's try making some changes to this project and testing them right on the device. The project can be modified and pushed again using the same method as above, but since we are using a development version of the OS, we can enable Local mode and push directly to the device for a faster development cycle.
Activate local mode on the device via the dashboard.
Once enabled, you can now use
balena push again, but this time we will push directly to the local IP address of the device obtained via the dashboard.
$ balena push 10.19.0.153
The same build process as before is carried out, but this time instead of using the balena builders, the build takes place locally on the device itself.

The balena CLI will now watch for changes to all the files within the project, and automatically push changes to the device when detected. Let's try making a change to title of our balena welcome page. Navigate to the
index.html file present in the
static directory of the project. Open the file and change the title from
Welcome to balena! to
Hello balena! and save the file. After saving the changes, you can observe balena CLI automatically start rebuilding only the parts of the Dockerfile that has been changed.

When the rebuild is complete, take a look at the public device URL again to see your changes. The welcome page should have been updated with the new title.
Once you've finished making your changes, disable local mode and the device will revert back to running the latest release that's on your fleet. To update your fleet with the latest changes you've just worked on, use
balena push <fleet name> once more to create a new release with those changes.
When it's finished building the device(s) will update as before. Remember anything pushed to the fleet in this way can be applied to 10+ or 1000+ devices with no extra effort! To continue learning, explore parts of the guide in more detail:
- Learn more about local mode, which allows you to build and sync code to your device locally for rapid development.
