Flash JetPack

This workflow installs JetPack 7.1 (L4T 38.4.0) to an NVMe SSD on the J601 carrier board. Choose the BSP for the installed module: J6015 for T5000 or J6014 for T4000.

caution

Flashing erases data on the target NVMe SSD. Back up important data before starting, and keep power and USB connected until flashing completes.

1

Prepare the Equipment

Step 1 · Set up the Ubuntu host and target hardware

Prepare the following equipment:

• J601 carrier board with a Jetson AGX Thor T5000 or T4000 module and suitable cooling
• NVMe M.2 2280 SSD installed in the Key M slot
• 19–48 V DC power supply connected through XT30
• Physical Ubuntu 22.04 or 24.04 host PC with at least 220 GB of free storage
• USB Type-C data cable
• HDMI display, keyboard, and mouse for first boot

tip

A native Ubuntu host provides the most reliable flashing experience. Seeed Jetson DevelopTool also supports Windows through WSL2; follow its installation guide for host setup.

Enter Force Recovery Mode

Step 2 · Connect J4 and verify the installed module

1. With the board powered off, connect the host PC to the USB 3.0 Type-C recovery/flashing port (J4). The USB 2.0 Type-C debug port (J3) is a separate connector.
2. Press and hold RECOVERY.
3. Connect the 19–48 V DC power supply through XT30.
4. Release RECOVERY after two seconds.
5. Run the following command on the Ubuntu host:

lsusb

Configuration	Module	Expected recovery USB ID
J6015	AGX Thor T5000	0955:7026 NVIDIA Corp.
J6014	AGX Thor T4000	0955:7226 NVIDIA Corp.

If the expected ID is missing, check the data cable and recovery port, then repeat the recovery sequence before continuing.

Prepare the Matching BSP

Step 3 · Choose software or command-line flashing

Software Flashing

Install and launch Seeed Jetson DevelopTool, then prepare the firmware:

1. Open Flash Center and select reComputer J601 and JetPack 7.1 (L4T 38.4.0).

2. Confirm the recovery wiring from Step 2.

3. Click Detect Device, confirm the installed module, and click Next.

4. Click Download / Prepare BSP. The tool downloads the firmware, verifies its SHA-256 checksum, and extracts the package.

Command-Line Flashing

Download the module-specific BSP package below. The archive is large; downloading may take around 60 minutes. Wait for the download to finish before extracting it.

Flash the NVMe SSD

Step 4 · Use the same flashing method and module selection

Software Flashing

Click Start Flash in Jetson DevelopTool and wait for the interface to report success. Keep the power supply and USB data cable connected throughout the process.

Command-Line Flashing

Extract the archive on the Ubuntu host, then run the command for your installed module. Replace YYYY-MM-DD with the date in the downloaded archive's filename.

AGX Thor T5000 (J6015)

cd <path-to-image>
sudo tar xpf mfi_recomputer-thor-carrier-j6015-7.1-38.4.0-YYYY-MM-DD.tar.gz
cd mfi_recomputer-thor-carrier-j6015
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --showlogs --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_t264_nvme.xml -S 80GiB --network usb0 recomputer-thor-carrier-j6015 external

AGX Thor T4000 (J6014)

cd <path-to-image>
sudo tar xpf mfi_recomputer-thor-carrier-j6014-7.1-38.4.0-YYYY-MM-DD.tar.gz
cd mfi_recomputer-thor-carrier-j6014
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --showlogs --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_t264_nvme.xml -S 80GiB --network usb0 recomputer-thor-carrier-j6014 external

The flash command usually takes 2–10 minutes. Wait for the terminal to report a successful flash.

5

Complete the First Boot

Step 5 · Configure Ubuntu and check your interfaces

Connect the HDMI display, keyboard, and mouse, and complete Ubuntu's initial system configuration. If the setup screen does not appear after flashing, power-cycle the board after the flashing tool reports success.

Continue with Hardware & I/O to verify your peripherals, or explore the perception demo. Seeed's carrier-board device-tree and BSP sources are available in Linux_for_Tegra.

Applications

Start with a camera-and-LiDAR perception example for reComputer Robotics J601.

DetectionSensor FusionBEV

Multi-Camera & LiDAR Perception

Replay six camera streams and LiDAR data while Jetson runs TensorRT detection, road segmentation, geometric bird's-eye-view fusion, and pose-aligned local mapping, with synchronized browser views.

Watch the Perception Demo

Get the Demo & Deployment Guide ↗Watch on YouTube ↗

The repository documents validation on JetPack 7.2 / L4T R39.2, CUDA 13.2, and TensorRT 10.16.2. Follow its environment and deployment instructions; this page's JetPack 7.1 flash package is a separate software baseline. Build TensorRT engines on the target device for the installed software versions.

The demo uses recorded nuScenes data and geometric camera/LiDAR fusion. Its local map uses dataset-provided poses; segmentation accuracy on nuScenes has not been evaluated. See the repository for validation conditions and dataset/model licenses.
