NVIDIA Jetson AGX Thor - IMX477 Driver
Overview IMX477 Driver
The IMX477 is a 12.3MP 1/2.3-inch CMOS image sensor from Sony that uses a MIPI CSI-2 interface and supports resolutions up to 4056×3040. It offers high image quality, good low-light performance, supports high frame rates at lower resolutions, and is controlled over I2C, making it suitable for embedded vision applications.
The J20 camera adapter connects to the Jetson 120-pin camera connector and exposes six MIPI CSI-2 connectors, allowing the connection of up to six IMX477 cameras or other CSI-2-compatible sensors to the Jetson platform. It provides signal routing, power regulation, and connector compatibility, enabling reliable high-resolution image capture for development and production systems.
RidgeRun has developed support for J20 adapter and IMX477 Driver in a custom board of NVIDIA Jetson AGX Thor.
Driver Features
The following table shows the features of the driver.
| Feature | Description |
|---|---|
| Format | 10-bit Bayer BGBG/GRGR |
| 10-bit Bayer RGRG/GBGB | |

| Connections (J20/Jetson) | J1_1 to CSI_0 |
| J2_1 to CSI_1 | |
| J1_2 to CSI_2 | |
| J2_2 to CSI_3 | |
| J1_3 to CSI_4 | |
| J2_3 to CSI_6 | |
| Camera controls | * Supports gain and exposure control (short and long), frame rate adjustment, and sensor configuration access. |
| * Additional options include bypass/override modes, low latency mode, preferred stride, capture timeout, and read-only sensor property packets for signal, image, and control data. |
GStreamer pipeline
You can use the following pipelines:
- To display video.
gst-launch-1.0 nvarguscamerasrc sensor-id=0 sensor-mode=2 num-buffers=1600 ! "video/x-raw(memory:NVMM),width=1920,height=1080,framerate=60/1" ! nvvidconv ! perf ! nv3dsink
- To generate a sample image.
gst-launch-1.0 nvarguscamerasrc sensor-mode=2 num-buffers=1 ! capsfilter caps="video/x-raw(memory:NVMM),width=1920,height=1080" ! perf ! queue ! nvvidconv ! queue ! nvjpegenc ! jpegparse ! filesink location=image.jpeg -e
You can change the resolution and framerate by changing the sensor mode.
| Sensor mode | Resolution and Framerate |
|---|---|
| 0 | 3840x2160@30fps |
| 1 | 1920x1520@60fps |
| 2 | 1920x1080@60fps |
The output will look like as follows.
