LVDS & MIPI Configuration

Once the board has booted with the LVDS and MIPI cameras connected, follow the steps below to configure the camera interface.

Warning

This page covers LVDS + MIPI dual-camera configuration. If you are using only an LVDS camera, go to LVDS Configuration instead.

Transfer Configuration File

Note:

• Contact Oppila Support for rc.local file.

• Copy the rc.local file from the Host PC to the USB storage device.

Step 1: Open Terminal on the Jetson

• Press Ctrl + Alt + T

Step 2: Copy rc.local to Jetson

Transfer the rc.local file from your PC to the home directory of the AstrOptix Board using a USB drive or SCP.

Run the following commands for copy the files to the jetson Orin Nano/NX

sudo cp /media/<username>/<pendrive_name>/rc.local /home/<username>/
sudo chmod +x rc.local

Replace the following placeholders with actual values:

• <username> - Your system username
• <pendrive_name> - The label/name of your USB storage device

Driver Configuration

Note

• Contact Oppila Support for lvdsmipi.ko and camconf.ko file.

• Copy the lvdsmipi.ko and camconf.ko files from the Host PC to the USB storage device.

Step 3: Navigate to Kernel Module Directory

Change the current working directory to the kernel module directory using the following command:

cd /lib/modules/5.15.148-tegra/updates/drivers/media/i2c/

Step 4: Copy Kernel Module from USB Storage

Execute the following command to copy the kernel module file from the USB storage device to the current directory:

sudo cp /media/<username>/<pendrive_name>/lvdsmipi.ko_<serial_no>.ko lvdsmipi.ko

Step 5: Copy Config Kernel Module from USB Storage

Execute the following command to copy the Config kernel module file from the USB storage device to the current directory:

sudo cp /media/<username>/<pendrive_name>/camconf.ko_<serial_no>.ko camconf.ko

Step 6: Copy Device tree file to “/boot” directory in the Jetson Orin Nano/NX

Execute the following command to copy the device tree file from the USB storage device to the boot directory:

sudo cp /media/<username>/<pendrive_name>/tegra234-p3767-camera-p3768-imx219-C.dtbo /boot/

Replace the following placeholders with actual values:

• <username> - Your system username
• <pendrive_name> - The label/name of your USB storage device
• <serial_no> - Contact Oppila Support for Serial Number

Kernel Module Configuration

Step 6: Navigate to the modules-load.d directory

cd /etc/modules-load.d/

Step 7: Create the original Kernel module configuration file for loading

sudo vi lvdsmipi.conf

• Inside the created file, write – lvdsmipi
• Save and close the file – Shift + ZZ

Step 8: Create the config Kernel module configuration file for loading

sudo vi camconf.conf

• Inside the created file, write – camconf
• Save and close the file – Shift + ZZ

Step 9: Run the below command to check the available Kernel modules to load

sudo depmod -a

Configure Device Tree Overlay

Note

This is a one-time configuration required after each new flash. It is not required on every boot.

Step 10: Open Terminal on the Jetson

Press Ctrl + Alt + T on the Jetson to open a terminal window.

Step 11: Run the Jetson-IO Configuration Tool

sudo /opt/nvidia/jetson-io/jetson-io.py

Step 12: Navigate to Configuration Menu

Follow the menu selections in order:

Select "Configure Jetson 24-pin CSI Connector":

Select "Configure for compatible hardware":

Select "Camera IMX219-A and IMX477-C":

Select "Save pin changes":

Select "Save and reboot to reconfigure pins":

Step 13: Press Any Key to Reboot

The system will reboot and reconfigure the MIPI pins for both cameras.

Info

• The system will shut down and restart. This process typically takes 30-60 seconds.
