MIPI AR0234 Setup Guide

This is setup guide for enabling MIPI AR0234 for Intel® Alder-Lake N processor.

Requirements

Ensure that your system is set up properly.

1. ADLN Setup: Refer to ADLN Setup tutorial
2. ADLN BIOS Setup: Refer to BIOS Setup for MIPI AR0234

Validated Hardware

• AAEON UP Squared Pro 7000 (UPN-ADLNI3-A10-1664)
• D3 AR0234 MIPI

Go to specific setup directory

This step will redirect user to the current platform setup directory

cd edge-developer-kit-reference-scripts/platforms/atom/adln/mipi/ar0234

Install IPU libraries

1. Run below script to install userspace IPU libraries.

   cd edge-developer-kit-reference-scripts/platforms/atom/adln/mipi/ar0234/scripts
   ./install_ipu.sh
   

2. After installing userspace IPU libraries, run below script to setup userspace IPU libraries. The system reboots after this command.

   ./setup_ipu.sh
   

3. To ensure IPU FW is probed and loaded properly, run this command.

   sudo dmesg | grep ipu
   

   

4. Lastly check if AR0234 sensor(s) are detected.

   sudo dmesg | grep ar0234
   

   

   media-ctl -p
   

   

Video Loopback Setup

1. In order to use v412 API with AR0234 MIPI camera, run following commands

   sudo modprobe v4l2loopback devices=2
   

   devices=x (number of AR0234 cameras connected)

2. You will get the video device name by running following command.

   ls -1 /sys/devices/virtual/video4linux
   

   Take note the device name (e.g. video131)

3. Run the following command to enter root mode.

   sudo bash
   

4. Set environment variables with following commands.

   cd edge-developer-kit-reference-scripts/platforms/atom/adln/mipi/ar0234/scripts
   source setup_camera_env.sh
   

AR0234 Camera Stream

Using icamerasrc

1. Launch the following command to see

   Single camera stream

   gst-launch-1.0 icamerasrc device-name=ar0234 printfps=true ! video/x-raw,format=NV12,width=1280,height=960 ! videoconvert ! xvimagesink
   

   Dual camera stream

   gst-launch-1.0 icamerasrc device-name=ar0234 printfps=true ! video/x-raw,format=NV12,width=1280,height=960 ! videoconvert ! xvimagesink icamerasrc device-name=ar0234-2 printfps=true ! video/x-raw,format=NV12,width=1280,height=960 ! videoconvert ! xvimagesink
   

Stream output

The images below shows the output for 2 AR0234 camera streams.
