Hardware Overview
Flash JetPack
Here, we will show you how to flash Jetpack to an NVMe SSD connected to the reComputer J4012/ J4011/ J3010 and J3011. All these devices come with J401 carrier board inside and the flashing procedure is the same for all.
reComputer J40/ J30 series comes with JetPack 5.1 pre-installed on the included NVMe SSD, so that you do not need to flash it. However, if you want to flash it again with JetPack, you can follow this guide.
Supported Module
- NVIDIA® Jetson Orin™ Nano Module 4GB
- NVIDIA® Jetson Orin™ Nano Module 8GB
- NVIDIA® Jetson Orin™ NX Module 8GB
- NVIDIA® Jetson Orin™ NX Module 16GB
Prerequisites
- Ubuntu Host Computer
- reComputer J4012/ J4011/ J3010 or J3011
- USB Type-C data transmission cable
We recommend that you use physical ubuntu host devices instead of virtual machines. Please refer to the table below to prepare the host machine.
| JetPack Version | Ubuntu Version (Host Computer) | ||
| 18.04 | 20.04 | 22.04 | |
| JetPack 5.x | ✅ | ✅ | |
| JetPack 6.x | ✅ | ✅ | |
Enter Force Recovery Mode
- We do not recommend using virtual machines and ARM architecture Ubuntu for flashing.
- 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. Use a jumper wire to connect the FC REC pin and the GND pin.
| Button Header | Description | Button Header | Description | |
|---|---|---|---|---|
 | 1 | PWR BTN | 7 | AUTO ON |
| 2 | GND | 8 | DIS | |
| 3 | FC REC | 9 | UART TXD | |
| 4 | GND | 10 | UART RXD | |
| 5 | SYS RET | 11 | LED + | |
| 6 | GND | 12 | LED - |
Step 2. Power up the reComputer by connecting the included cable from the power adapter and connect the board with the Ubuntu host PC with a USB Type-C data transmission cable
Step 3. 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 NX 16GB
Step 4. Remove the jumper wire
Flash to Jetson
Before moving onto flashing, it should be noted that Jetson Orin NX module only supports JetPack 5.1 and above, while Jetson Orin Nano module only supports JetPack 5.1.1 and above.
First of all, install the below required dependencies on the Ubuntu Host PC before moving onto flashing JetPack.
sudo apt install qemu-user-static sshpass abootimg nfs-kernel-server libxml2-utils binutils -y
- JP5.1.1
- JP5.1.2
- JP6.0
Here we will use NVIDIA L4T 35.3.1 to install Jetpack 5.1.1 on the reComputer
Step 1: Download the NVIDIA drivers on the host PC. The required drivers are shown below:
Step 2: Extract Jetson_Linux_R35.3.1_aarch64 and Tegra_Linux_Sample-Root-Filesystem_R35.3.1_aarch64 by navigating to the folder containing these files, apply the changes and install the necessary prerequisites
tar xf Jetson_Linux_R35.3.1_aarch64
sudo tar xpf Tegra_Linux_Sample-Root-Filesystem_R35.3.1_aarch64 -C Linux_for_Tegra/rootfs/
cd Linux_for_Tegra/
sudo ./apply_binaries.sh
sudo ./tools/l4t_flash_prerequisites.sh
Step 3 (Optional): Configure your username, password & hostname so that you do not need to enter the Ubuntu installation wizard after the device finishes booting
sudo tools/l4t_create_default_user.sh -u {USERNAME} -p {PASSWORD} -a -n {HOSTNAME} --accept-license
For example (username:"nvidia", password:"nvidia", device-name:"nvidia-desktop"):
sudo tools/l4t_create_default_user.sh -u nvidia -p nvidia -a -n nvidia-desktop --accept-license
Step 4: Flash the system to the NVMe SSD
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
-c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
--showlogs --network usb0 p3509-a02+p3767-0000 internal
You will see the following output if the flashing process is successful
Now, you can connect the mouse, keyboard, and monitor to the Jetson device. It will be ready to use!
If your Jetson device takes a long time to open the desktop, please reconnect the power supply.
Step 5 (Optional): Install Nvidia Jetpack SDK
Please open the terminal on the Jetson device and execute the following commands:
sudo apt update
sudo apt install nvidia-jetpack
Here we will use NVIDIA L4T 35.4.1 to install Jetpack 5.1.2 on the reComputer
Step 1: Download the NVIDIA drivers on the host PC. The required drivers are shown below:
Step 2: Extract Jetson_Linux_R35.4.1_aarch64 and Tegra_Linux_Sample-Root-Filesystem_R35.4.1_aarch64 by navigating to the folder containing these files, apply the changes and install the necessary prerequisites
tar xf Jetson_Linux_R35.4.1_aarch64.tbz2
sudo tar xpf Tegra_Linux_Sample-Root-Filesystem_R35.4.1_aarch64.tbz2 -C Linux_for_Tegra/rootfs/
cd Linux_for_Tegra/
sudo ./apply_binaries.sh
sudo ./tools/l4t_flash_prerequisites.sh
Now we need to apply a patch from NVIDIA which is needed for JP5.1.2 and explained here in section 4.2.3 of the official NVIDIA JetPack Release Notes.
Step 3: Navigate to the following directory
cd Linux_for_Tegra/bootloader/t186ref/BCT
Step 4: Open the file "tegra234-mb2-bct-scr-p3767-0000.dts" and add the following lines under tfc section
tfc {
reg@322 { /* GPIO_M_SCR_00_0 */
exclusion-info = <2>;
value = <0x38008080>;
};
Step 5 (Optional): Navigate to "Linux_for_Tegra" directory, and enter the below command to configure your username, password & hostname so that you do not need to enter the Ubuntu installation wizard after the device finishes booting
cd Linux_for_Tegra
sudo tools/l4t_create_default_user.sh -u {USERNAME} -p {PASSWORD} -a -n {HOSTNAME} --accept-license
For example (username:"nvidia", password:"nvidia", device-name:"nvidia-desktop"):
sudo tools/l4t_create_default_user.sh -u nvidia -p nvidia -a -n nvidia-desktop --accept-license
Step 6: Flash the system to the NVMe SSD
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
-c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
--showlogs --network usb0 p3509-a02+p3767-0000 internal
You will see the following output if the flashing process is successful
Now, you can connect the mouse, keyboard, and monitor to the Jetson device. It will be ready to use!
If your Jetson device takes a long time to open the desktop, please reconnect the power supply.
Step 7 (Optional): Install Nvidia Jetpack SDK
Please open the terminal on the Jetson device and execute the following commands:
sudo apt update
sudo apt install nvidia-jetpack
Here we will use NVIDIA L4T 36.3 to install Jetpack 6.0 on the reComputer
Step 1: Download the system image to your Ubuntu PC corresponding to the Jetson module you are using:
| Jetson Module | Download Link | Alternative Image Link | JetPack Version | L4T Version |
|---|---|---|---|---|
| Jetson Orin NX 16GB | Download1 | Download2 | 6.0 | 36.3 |
| Jetson Orin NX 8GB | Download1 | Download2 | ||
| Jetson Orin Nano 8GB | Download1 | Download2 | ||
| Jetson Orin Nano 4GB | Download1 | Download2 |
* The image files from both Download1 and Download2 are the same. You can choose the link with the faster download speed.
Step 2: Extract the downloaded image file:
sudo tar xpf mfi_xxxx.tar.gz
# For example: sudo tar xpf mfi_recomputer-orin-nano-8g-j401-6.0-36.3.0-2024-06-07.tar.gz
Step 3: Navigate to the unzipped directory and execute the following command to flash jetpack system to the NVMe SSD:
cd mfi_xxxx
# For example: cd mfi_recomputer-orin-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 4: Connect the J401 to a display using the HDMI connector on the board and finish the initial configuration setup:
Please complete the System Configuration according to your needs.
Step 5: After starting the system, you need to execute the following command to reactivate the wireless network card driver:
sudo rm /lib/modules/5.15.136-tegra/build
sudo ln -s /usr/src/linux-headers-5.15.136-tegra-ubuntu22.04_aarch64/3rdparty/canonical/linux-jammy/kernel-source/ /lib/modules/5.15.136-tegra/build
sudo apt install -y iwlwifi-modules
