Host Setup & Flashing
This phase prepares the host PC environment, extracts the pre-built L4T Oppila image, and flashes it to the AstrOptix Board 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 pipPrepare Working Directory
Step 2: Download Required Files
Download rc.local and OPPILA_ASTROPTIX.tar.bz2 from the link provided by the Oppila Support.
Step 3: Create a Working Directory
mkdir ~/OPPILA_ASTROPTIXStep 4: Move the Downloaded Image
mv ~/Downloads/ORIN_NX_IMAGE_ASTROPTIX.tar.bz2 ~/OPPILA_ASTROPTIX/Step 5: Navigate to the New Directory
cd ~/OPPILA_ASTROPTIX/Extract the OS Image
Step 6: Extract the Archive
Run the following command. Extraction may take several minutes:
sudo tar -xvJf ORIN_NX_IMAGE_ASTROPTIX.tar.bz2Once complete, a directory named Linux_for_Tegra will be created inside ~/OPPILA_ASTROPTIX/.
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, 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.
- 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
lsusbLook 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 nvme0n1p1A successful flash is shown in the image below:

Note
The flashing may take around 10-15 minutes.
Post-Flash Setup
Once flashing is complete:
Power off the AstrOptix Board and disconnect the power cable.
Remove the jumper from the J7(3rd and 4th pins) recovery mode pins.
Connect your camera to the AstrOptix Board:
- LVDS camera → J13 connector (bottom side)
- MIPI camera → J8 connector (top side)
Power on the AstrOptix Board with Orin Nano/NX Module.
