NVIDIA Jetson Orin NX- Getting Started with JetPack 5.1.1
You will need the NVIDIA SDK Manager for flashing your Orin NX. In this section, you will learn about the NVIDIA SDK Manager and the system requirements to use it.
The NVIDIA SDK Manager is the tool that allows developers to set up the development environment, get the JetPack SDK, and optionally flash the Orin NX. The NVIDIA SDK Manager runs on a host computer, not in the Orin NX. The Host computer must have:
- Ubuntu Linux x64_64 16.04, 18.04 and 20.04 or CentOS/RHEL 7.6, 8.0 and 8.2 on x86_64 system.
- Internet connection.
- At least 50GB of disk space.
- 8GB of RAM.
Get the SDK Manager
This section assumes that you are working on a host computer that meets the requirements above. The steps to get the SDK Manager installed on your host computer are:
1. Download the SDK Manager installer from https://developer.nvidia.com/sdkmanager_deb. You will need to log in or register into your NVIDIA developer account to download the SDK Manager installer.
2. Install the SDK Manager by running the following command in a terminal:
 | Note: Make sure to replace the <SDK_Manager_Installer_Download_Dir> with the actual path of the directory where the SDK Manager installer was stored in step 1. |
| Note: Make sure to replace the <version> and <build> values with the appropriate ones according to the name of the installer downloaded in step 1. |
sudo dpkg -i <SDK_Manager_Installer_Download_Dir>/sdkmanager_<version>-<build>_amd64.deb
For example, if the file downloaded from NVIDIA is named sdkmanager_1.9.2-10899_amd64.deb, then you can use the following command to install it:
sudo dpkg -i <SDK_Manager_Installer_Download_Dir>/sdkmanager_1.9.2-10899_amd64.deb
3. Verify that the installation was successful by launching the SDK Manager with the following command:
sdkmanager
At this point, you should see the SDK Manager UI login window as shown in Figure 1.
The version of the SDK Manager is displayed in the top left corner of the window, in the example in Figure 1, the version is 1.9.2.10899. Another way to verify the SDK Manager version is to run the following command in the terminal:
| Note: Only one instance of the SDK Manager can be open at a given time in your host system, therefore if you already have the SDK manager UI and want to try the following command, make sure to close the UI first. |
sdkmanager --ver
The version printed in the terminal depends on your SDK Manager version, but it should be something like the following:
1.8.0.10363
At this point you should be ready to install Jetpack.
