Omnivision AR0820 Features
The AR0820AT is a 1/2−inch CMOS digital image sensor with a 3848 H x 2168 V active−pixel array. This advanced automotive sensor captures images in either linear or high dynamic range, with rolling−shutter readout.
AR0820AT is optimized for both low light and challenging high dynamic range scene performance, with a 2.1 µm DR−Pix BSI pixel and on−sensor 140 dB HDR capture capability. The sensor includes advanced functions such as in−pixel binning, windowing, and both video and single frame modes to provide flexible Region of Interest (ROI) or specific resolution in order to enhance performance in extreme low light conditions. The sophisticated sensor fault detection features and embedded data on AR0820AT are designed to enable camera ASIL B compliance. The device is programmable through a simple two−wire serial interface and supports MIPI output interface.

Enabling the Driver
In order to use this driver, you have to patch and compile the kernel source using JetPack:
- Follow the instructions to get the kernel source code.
- Once you have the source code, apply the following the patches in order to add the changes required for the IMX327 camera at kernel and dtb level.
4.5.1_ar0820.patch
- Follow the instructions for building the kernel, and then flash the image.
Make sure to enable ar0820 driver support:
make menuconfig
-> Device Drivers
-> Multimedia support (MEDIA_SUPPORT [=y])
-> NVIDIA overlay Encoders, decoders, sensors and other helper chips
-> MAX9296 Deserializer I2C IO Expander (I2C_IOEXPANDER_DESER_MAX9296 [=y])
Using the Driver
GStreamer Examples
Capture and Display
- 1920x1080@30fps RGGB12

Video Encoding
CAPS="video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)NV12, framerate=(fraction)30/1" gst-launch-1.0 nvarguscamerasrc sensor-id=0 num-buffers=500 !

The sensor will capture in the 1920x1080@30fps mode and the pipeline will encode the video and save it into test.ts file.
