Host Setup & Flashing

This phase prepares the host PC environment, extracts the pre-built L4T Oppila image, and flashes it to the AstrOptix Board V2 via recovery mode.

Install Dependencies

Note

Skip step 1 if you have already installed the dependencies on the host machine.

Step 1: Update Package Lists and Install Required Packages

sudo apt update
sudo apt install -y qemu-user-static sshpass binutils abootimg libxml2-utils nfs-kernel-server u-boot-tools android-tools-fastboot python3-pip lz4
pip3 install -U pip

Prepare Working Directory

Step 2: Download Required Files

Download OPPILA_ORIN_L4T_36.5.0_ASTROPTIX.tar.bz2 provided by the Oppila Support.

Step 3: Create a Working Directory

mkdir ~/OPPILA_ORIN_L4T_36.5.0_ASTROPTIX

Step 4: Move the Downloaded Image

mv ~/Downloads/OPPILA_ORIN_L4T_36.5.0_ASTROPTIX.tar.bz2 ~/OPPILA_ORIN_L4T_36.5.0_ASTROPTIX/

Step 5: Navigate to the New Directory

cd ~/OPPILA_ORIN_L4T_36.5.0_ASTROPTIX/

Extract the OS Image

Step 6: Extract the Archive

Run the following command. Extraction may take several minutes:

sudo tar -xvJf OPPILA_ORIN_L4T_36.5.0_ASTROPTIX.tar.bz2

Once complete, a directory named Linux_for_Tegra will be created inside the extracted folder.

Step 7: Navigate to the Extracted Directory

cd Linux_for_Tegra/

Set Recovery Mode

Step 8: Recovery Mode Setup

On the AstrOptix AI Carrier Board V2, short J7 Pin 3 (GND) to J7 Pin 4 (FORCE REC) using a jumper wire, as shown below.

After placing the jumper:

• Connect the Jetson Orin Nano/NX module to the AstrOptix AI Carrier Board V2.
• Insert an NVMe SSD into the M.2 Key M slot (J14).
• Connect a USB Type-C cable from J11 to the host PC.
• Power on the board using the provided adapter.

Verify Device Detection

Step 9: Check Jetson Orin Nano/NX is detected in Recovery Mode on Host PC terminal

Look for an entry such as: NVIDIA Corp. APX

Note

If the device is not visible, try a different USB cable or ensure jumper is placed in FC REC and GND pins.

Flashing Image

Step 10: Execute the below command to flash image from Host PC to Jetson Orin Nano/Nx

sudo ./nvsdkmanager_flash.sh --storage nvme0n1p1

A successful flash is shown in the image below:

Note

The flashing may take around 10-15 minutes.
