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.


  • Ubuntu Host PC (native or VM using VMware Workstation Player)
  • reComputer J4012/ J4011/ J3010 and J3011
  • USB Type-C data transmission cable

Enter Force Recovery Mode

Before we can move on to the installation steps, we need to make sure that the reComputer is in force recovery mode.

Step 1. Use a jumper wire to connect the FC REC pin and the GND pin.

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

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 ./
sudo ./tools/

Step 3: Configure your username, password & hostname so that you do not need to enter the Ubuntu installation wizard after the device finishes booting

sudo tools/ -u {USERNAME} -p {PASSWORD} -a -n {HOSTNAME} --accept-license

For example (username:"nvidia", password:"nvidia", device-name:"nvidia-desktop"):

sudo tools/ -u nvidia -p nvidia -a -n nvidia-desktop --accept-license

Step 4: Flash the system to the NVMe SSD

sudo ./tools/kernel_flash/ --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
