Updating Your NVIDIA Jetson Orin NX: A Comprehensive Guide
Keeping your NVIDIA Jetson Orin NX up-to-date with the latest firmware is essential for ensuring optimal performance and accessing new features. This guide provides a detailed walkthrough of updating your device using Ubuntu 22.04 as a virtual machine environment, explaining each step to help you confidently update your module.
##
Prerequisites
Before you begin updating your NVIDIA Jetson Orin NX module, ensure you have the following setup and tools ready:
- An NVIDIA Jetson Orin NX module.
- A compatible host PC running Ubuntu 22.04.
- Internet access for downloading necessary files.
- Basic familiarity with Linux terminal commands.
###
Preparation Steps
**Step 1:** Use a jumper wire to connect the **FC REC** pin and the **GND** pin on your reComputer board. This step is crucial as it prepares the device to enter force recovery mode, which is required for flashing new firmware.
**Step 2:** Power up the reComputer by connecting the included cable from the power adapter. Then, connect the board with the Ubuntu host PC using a USB Type-C data transmission cable. Ensure that both devices are properly connected and powered on.
**Step 3:** On your Linux host PC, open a Terminal window. Enter the command `lsusb` to list all USB devices currently recognized by the system. If the returned content includes one of the following outputs according to the Jetson SoM you use, then the board is in force recovery mode:
- For Orin NX 16GB: **0955:7323 NVidia Corp**Corp
This output confirms that your device is correctly set up for flashing.
**Step 4:** Once confirmed, remove the jumper wire from the **FC REC** and **GND** pins. This step finalizes the preparation process before proceeding with the firmware update.

Step-by-Step Guide
###
Step 1: Download the System Image
First, download the system image corresponding to your Jetson module from [Seeed Studio's website](https://wiki.seeedstudio.com/reComputer_J4012_Flash_Jetpack/#tech-support--product-discussion). For the Jetson Orin NX 16GB, you will need JetPack version 6.1 and L4T version 36.4.
**Why This Step?**
Downloading the system image is crucial as it contains all necessary files to install or update your Jetson module's firmware. The image provides a clean slate, ensuring no residual data from previous installations interferes with the new setup.
###
Step 2: Extract the Downloaded Image
Once downloaded, extract the image file using:
```bash
sudo tar xpf mfi_xxxx.tar.gz
```For example:
```bash
sudo tar xpf mfi_recomputer-orin-nx-16g-j401-6.1-36.4.0-2024-12-04.tar
```**Why This Step?**
Extracting the image file is necessary to access its contents, which include scripts and configuration files required for flashing your Jetson module.
###
Step 3: Flash the System Image
```bash
cd mfi_xxxx
```For example:
```bash
cd mfi_recomputer-orin-j401
```Execute the following command to flash the JetPack system onto the NVMe SSD:
```bash
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --network usb0 --showlogs
```**Why This Step?**
This script is crucial for flashing the firmware. The `--flash-only` option ensures that only the system image is flashed, not any additional components. `--network usb0` sets up a USB connection for data transfer. `--showlogs` provides detailed logs of the flashing process.
###
Step 4: Initial Configuration Setup
Connect your J401 module to a display using the HDMI connector. This step is necessary for configuring user settings such as username, hostname, and IP address.
**Why This Step?**
Initial configuration ensures that your Jetson module can communicate with other devices on your network and allows you to customize its settings according to your needs.
##
Post-Install Steps
After flashing, perform the following steps to set up additional tools and configurations:
###
Install NVIDIA Container Toolkit and Docker
```bash
sudo apt install -y nvidia-container-toolkit curl
curl https://get.docker.com | sh && sudo systemctl --now enable docker
```**Why This Step?**
Installing Docker allows you to run containerized applications, which is essential for development environments. The NVIDIA Container Toolkit enables GPU acceleration within these containers.
###
Configure Docker Runtime
```bash
sudo nvidia-ctk runtime configure --runtime=docker
mkdir /docker
sudo mkdir /docker
```**Why This Step?**
Configuring the Docker runtime with NVIDIA support ensures that your containers can leverage the Jetson module's GPU capabilities, enhancing performance for compute-intensive tasks.
###
Set Up Docker Daemon Configuration
Edit the Docker daemon configuration:
```bash
sudo nano /etc/docker/daemon.json
```Add the following content to enable NVIDIA runtime:
```json
{
"runtimes": {
"nvidia": {
"path": "/usr/bin/nvidia-container-runtime",
"runtimeArgs": []
}
}
}
```Reload and restart Docker:
```bash
sudo systemctl daemon-reload && sudo systemctl restart docker
```**Why This Step?**
This configuration ensures that Docker uses the NVIDIA runtime by default, allowing seamless integration of GPU resources.
###
Deploy Portainer Agent
Run the following command to deploy Portainer, a management tool for Docker environments:
```bash
sudo docker run -d -p 9001:9001 --name portainer_agent --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /docker/volumes:/var/lib/docker/volumes portainer/agent:latest
```**Why This Step?**
Portainer provides a user-friendly interface for managing Docker containers, making it easier to deploy and monitor applications.
### System Configuration
Switch to multi-user mode:
```bash
sudo init 3
sudo systemctl set-default multi-user.target
```Disable unnecessary services:
```bash
sudo systemctl disable nvargus-daemon.service
sudo systemctl disable nvzramconfig
```**Why This Step?**
Disabling these services reduces boot time and frees up resources, optimizing the system for your specific use case.
###
Set Up Swap Space
Create a swap file to improve performance:
```bash
sudo fallocate -l 16G /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
```Edit `/etc/fstab` to make the swap persistent across reboots:
```bash
sudo nano /etc/fstab
```Add the following line:
```
/swapfile none swap sw 0 0
```**Why This Step?**
Swap space provides additional virtual memory, which can be crucial for performance when running memory-intensive applications.
###
Install Python and Jetson Stats
Install Python pip and update it:
```bash
sudo apt install python3-pip
sudo pip3 install -U jetson-stats
```Run `jtop` to monitor system resources:
```bash
jtop
```**Why This Step?**
`jetson-stats` is a tool that provides real-time monitoring of your Jetson module's performance, similar to the popular `htop` utility on Linux. It helps you keep track of CPU, GPU, and memory usage.
##
Conclusion
Updating your Jetson Orin NX with the latest firmware ensures you have access to new features and improvements. By following this detailed guide, you can confidently flash your device and configure it for optimal performance. Whether you're developing AI applications or running compute-intensive tasks, these steps will help you get the most out of your NVIDIA Jetson module.
This comprehensive update process not only enhances system capabilities but also ensures security and efficiency in technology development environments. Stay ahead with the latest advancements by keeping your hardware up-to-date!
