Prepare the Jetpack Image
Here, we need to download the system image to our Ubuntu PC corresponding to the Jetson module we are using:
| Jetpack Version | Jetson Module | GMSL | Download Link1 | SHA256 |
|---|---|---|---|---|
| 6.2 | Orin Nano 4GB | ✅ | Download | 260D30AF2DF259418A9A3BC47FCFDE9 97428461B133B408FB4B8BAB72F994E82 |
| Orin Nano 8GB | ✅ | Download | 379F2AC4BD574A7E5C8F8834F57BDC5 9FFA7BCFE0FDCBBF530CB7B4ED95E690D | |
| Orin NX 8GB | ✅ | Download | 8689D936F400B2AA8E603095E2E5EAA 5CF736DBD3EEB34E30DC98BD195B1235A | |

The Jetpack6 image file is approximately 14.2GB in size and should take around 60 minutes to download. Please kindly wait for the download to complete.
To verify the integrity of the downloaded firmware, you can compare the SHA256 hash value.
On an Ubuntu host machine, open the terminal and run the command sha256sum <File> to obtain the SHA256 hash value of the downloaded file. If the resulting hash matches the SHA256 hash provided in the wiki, it confirms that the firmware you downloaded is complete and intact.
Enter Force Recovery Mode
Before we can move on to the installation steps, we need to make sure that the board is in force recovery mode.
Step-by-Step
Step 1. Switch the switch to the RESET mode.
Step 2. Power up the carrier board by connecting the power cable.
Step 3. Connect the board to the Ubuntu host PC with a USB Type-C data transmission cable.
Step 4. On the Linux host PC, open a Terminal window and enter the command lsusb. If the returned content has 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
- For Orin NX 8GB: 0955:7423 NVidia Corp
- For Orin Nano 8GB: 0955:7523 NVidia Corp
- For Orin Nano 4GB: 0955:7623 NVidia Corp
The below image is for Orin Nano 8GB
Flash to Jetson
Step 1: Extract the downloaded image file:
cd <path-to-image>
sudo tar xpf mfi_xxxx.tar.gz
# For example: sudo tar xpf mfi_recomputer-robo-orin-nano-8g-j401-6.2-36.4.3-2025-05-23.tar.gz
Step 2: Execute the following command to flash jetpack system to the NVMe SSD:
cd mfi_xxxx
# For example: cd mfi_recomputer-orin-robotics-j401
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 1 --network usb0 --showlogs
You will see the following output if the flashing process is successful
The flash command may run for 2-10 minutes.
Step 3: Connect the Robotics J401 to a display use the PD to HDMI adapter to connect to a display that supports HDMI input, or directly connect to a display that supports PD input using the PD cable, and finish the initial configuration setup:
Please complete the System Configuration according to your needs.
