How to use VEYE and CS series camera module on NVIDIA Jetson Nano,TX2,AGX Xavier and Xavier NX

1 Overview

This guide shows how to use VEYE and CS series camera modules on Jetson Nano,Jetson Nano 2GB,TX2,AGX Xavier and Xavier NX. Jetson SDK Version is

  • Jetpack4.2.2,L4T r32.2.1
  • Jetpack4.3,L4T r32.3.1
  • Jetpack4.4,L4T r32.4.3
  • Jetpack4.4.1,L4T r32.4.4
  • Jetpack4.5,L4T r32.5

1.1 Check the current L4T version

First check the current L4T version and try to replace it with the same version.

cat /etc/nv_tegra_release

If it shows:

# R32 (release), REVISION: 4.3......

It means L4t Verion is 32.4.3

We provide two ways to do so: Prebuilt Binaries or Source Code. Yes, It's Open Source!

VEYE and CS series camera modules are camera module with ISP functions build in. It output UYVY data using MIPI-CSI2. We provide V4L2 interface for video streaming apps , and Video Control Toolkits (which is Shell Script) to control the camera module directly, which is called DRA(Directly Register Access).

2 Hardware Setup

We have designed a 6cam interposer board for TX2 devkit and Xavier, It support up to 6 cameras at the same time.

3 Upgrade Jetson Nano, Jetson TX2, AGX Xavier and Xavier NX system

3.1 Overview

This section describes how to upgrade the Jetson system to support our camera module. To support our camera module, we need to update the two parts of the L4T (Linux for Tegra) of the Jetson system, Image and DTB.

In the Image, we added the camera driver, while the DTB indicates the camera model used. In general, you only need to use the Image and DTB, that we have prebuilt, and you don't need to build from source when it is not necessary.

In particular, for Xavier NX, we provide a burning image of the TF card.

3.2 Burning the prebuilt Image to upgrade Jetson Nano and Xavier NX Devkit

This method is no longer recommended because in this mode, the DTB partition reverts to the default value in some cases. It is recommended to use pre-compiled Image and DTB for driver upgrade.

You can use the image prebuild by us to upgrade jetson Xavier NX system, which will support our camera.

Using whole prebuilt image

  • download ：

3.5 Upgrade Jetson Nano and Xavier NX 、AGX Xavierwithout HOST PC

Note: AGX Xavie Jetpack version >= 4.5 , support this upgrade mode. Earlier versions have not been verified and are not recommended.

3.5.1 Check the current L4T version

First check the current L4T version and try to replace it with the same version.

cat /etc/nv_tegra_release

If it shows:

# R32 (release), REVISION: 4.3......

It means L4t Verion is 32.4.3

3.5.2 Download the bsp package to the Jetson board

On Jetson Nano or Xavier NX:

git clone https://github.com/veyeimaging/nvidia_jetson_veye_bsp.git

3.5.3 Upgrade Image

First, under the bsp package directory, find the corresponding version of the Image package, decompress it, and execute:

sudo cp <path to your Image dir>/Image /boot/Image -f

For Xavier NX Devkit

Need to use the signed file(For example，file inside Image_l4t_r32.*.*_veyecam_signed_4_xavier),copy Image and Image.sig to /boot/ dir on the Jetson Xavier board:

sudo cp <path to your Image dir>/Image /boot/Image -f

sudo cp <path to your Image dir>/Image.sig /boot/Image -f

Effective after restart.

3.5.4 Upgrade dtb

Under the bsp package directory, find the dtb file corresponding to your camera module model and L4T version number.

sudo cp <path to your dtb dir>/<DTB file name> /boot/ -f

Then, edit the / boot/extlinux/extlinux.conf file and add the following line.

FDT /boot/<DTB file name>

Effective after restart.

3.6 Upgrade Jetson Board using Host PC

3.6.1 Setting Up the Host PC Environment And Burn the standard Image

Note: if your Jetson board has correctly burned the standard version Image, you can skip this step.

  • Cross-compiling Toolchain

The output message appears as shown below.

videoX  

4.2 Video Stream Toolkits Manual

Our camera appears as /dev/videoX device node,where X is between [0-5].

in gstreamer command ，v4l2src has a param device=/dev/videoX to identify which camera to use.

4.2.1 Gstreamer Usage
  • Preview FHD(HW accelerated)

gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false

  • Preview FHD(using xvimagesink sink)

export DISPLAY=:0

gst-launch-1.0 -e v4l2src io-mode=4 device=/dev/video0 do-timestamp=true ! 'video/x-raw, width=1920, height=1080, framerate=30/1, format=UYVY' ! xvimagesink sync=false

  • Preview 720p@60 (CS-MIPI-IMX307,HW accelerated)

  • Gstreamer cmd line for OpenCV

I think maybe OpenCV do not support I420 data format input，so you should convert it to BGR format.

gst-launch-1.0 v4l2src ! video/x-raw, format=(string)UYVY, width=(int)1920, height=(int)1080 ! nvvidconv ! video/x-raw(memory:NVMM), format=(string)I420 ！ nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink

  • Record FHD in H.264 format to a video file（HW accelerated）

gst-launch-1.0 v4l2src num-buffers=300 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! omxh264enc qp-range=20,20:20,20:-1,-1 ! matroskamux ! queue ! filesink location=videoname.mkv

  • Playback of saved video file (HW accelerated）

gst-launch-1.0 filesrc location=videoname.mkv ! matroskademux ! h264parse ! omxh264dec ! nvoverlaysink

  • Capturing FHD still image

4.3 Video Control Toolkits Manual

  • i2c bus description：

For AGX-Xavier and TX2, ADP-N1 has 6 MIPI CSI-2 interface [A-F]，the corresponding i2c address is[30-35].

For Xavier NX, the corresponding i2c address is 9 and10.

For Nano A02, the corresponding i2c address is 6.

For Nano B01, the corresponding i2c address is 7 and 8.

It is also the same as the X part of dmesg message:

subdev veye327 X-003b bound

subdev csimx307 X-003b bound

subdev cssc132 X-003b bound

using -b option to identify which bus you want to use.

5.1 Hardware Setup

CS-MIPI-IMX307 and RTSO-9001（TX2）


Matching with Realtimes RTSO-9001, you need to use RTST-RPI adapter board.

Note: the power supply capacity of the MIPI CSI-2 interface of the current version of RTSO-9001 is not enough to support the power requirements of our camera, which requires an additional 5V power supply to the camera. It is not shown in the picture above.

5.2 Software bsp

  • The corresponding directory for Realtimes RTSO-9001, is：

nvidia_jetson_veye_bsp\TX2\JetPack_4.2.2_Linux_RTSO-9001

  • Subject to the agreement with Ruitai, we do not release the source code
  • Our code have been submitted to Realtimes, and customers are advised to contact Realtimes for a complete version of the supported image.
