1.2 How to check the current L4T version
On Jetson board
cat /etc/nv_tegra_release
If it shows:
# R32 (release), REVISION: 4.3......
It means L4t Version is 32.4.3
2 Hardware Setup
We have designed a 6cam interposer board for TX2 devkit,Xavier and Orin, It support up to 6 cameras at the same time.
In particular, the VEYE-MIPI-IMX335 must use a 12V DC terminal to provide auxiliary power due to its high power consumption. Refer to J11 of ADP-N1.
2.1 NVIDIA TX2 Developer Kit
It is connected as shown in figure:
Be sure to screw the ADP adapter board to the bottom board.
2.2 NVIDIA AGX Xavier(the same with Orin)
Be sure to screw the ADP adapter board to the bottom board.
2.3 NVIDIA Nano ，TX2 NX and Xavier NX Devkit
The Xavier NX interface is compatible with raspberry pi and Jetson Nano. The connection mode is shown in figure:
3 Upgrade Jetson Nano, Jetson TX2, TX2 NX,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.
3.2 BSP package introduction
3.2.1 Path
https://github.com/veyeimaging/nvidia_jetson_veye_bsp
3.2.2 bsp package includes：
- prebuild linux kernel：Image（published in release package）
- prebuild dtb for different boards
- driver source code
- dts source code
- i2c toolkits
3.3 DTB file name and Jetson Board
3.3.1 Nano A02
tegra210-p3448-0000-p3449-0000-a02.dtb
3.3.2 Nano B01
tegra210-p3448-0000-p3449-0000-b00.dtb
3.3.3 Nano 2GB
tegra210-p3448-0003-p3542-0000.dtb
3.3.4 TX2 Devkit
tegra186-quill-p3310-1000-c03-00-base.dtb
3.3.5 TX2 NX(p3509-0000 carrier board)
use the same carrier board with XAVIER NX Devkit
tegra186-p3636-0001-p3509-0000-a01.dtb
3.3.6 AGX XAVIER
tegra194-p2888-0001-p2822-0000.dtb
3.3.7 XAVIER NX Devkit
tegra194-p3668-all-p3509-0000.dtb
3.4 DTB file name and camera module correspondence
Under the dtb directory of each motherboard, the directory corresponding to the camera model is stored, and you can usually know the corresponding camera model directly by the directory name.
Specially:
1, VEYE-MIPI-CAM2M is the new version of VEYE series dtb, which supports all VEYE 2M series products, including VEYE-MIPI-327E, VEYE-MIPI-IMX327S, VEYE-MIPI-IMX462, VEYE-MIPI-IMX385.
2, The ones with fpdlink as suffix correspond to fpdlink coaxial model module.
3.5 Upgrade Jetson Nano and Xavier NX 、AGX Xavier without HOST PC
Note: AGX Xavie Jetpack version >= 4.4 , 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 Board:
wget https://github.com/veyeimaging/nvidia_jetson_veye_bsp/releases/latest/download/nvidia_jetson_veye_bsp.tgz
tar -xzvf nvidia_jetson_veye_bsp.tgz
3.5.3 Upgrade Image
Backup old version Image
cp /boot/Image /boot/Image.backup
cp /boot/Image.sig /boot/Image.sig.backup
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.sig -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
Backup extlinux.conf file first
cp /boot/extlinux/extlinux.conf / boot/extlinux/extlinux.conf .back
Then, edit the /boot/extlinux/extlinux.conf file and add the following line.
FDT /boot/<DTB file name>
Note: <DTB file name> should be replaced with the corresponding dtb name of the mainboard, ensure that the file specified in the FDT line actually exists correctly.
Effective after restart.
3.6 Upgrade Jetson Board using Host PC
3.6.1 Burn the standard Image
Note: if your Jetson board has correctly burned the standard version Image, you can skip this step.
You can burn the standard Image using SDK Manager or following the steps below.

videoX
4.2 Video Stream Toolkits Manual
Our camera appears as /dev/videoX device node,where X is between [0-5].
Our camera module, mapped as /dev/videoX device node in the Jetson system.
During the OS boot process, the cameras are detected in the order of i2c bus from smallest to largest. For example, if only one camera is connected, X is 0 regardless of the hardware connection to the location. if 5 cameras are connected, X is reflected as [0-4] according to i2c bus from smallest to largest.
in gstreamer command ，v4l2src has a param device=/dev/videoX to identify which camera to use.

5 Realtimes RTSO-9001
5.1 Hardware Setup
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.
6 Document History
- 20220110
Add VEYE-MIPI-IMX385 support.
- 20220105
Use nvv4l2h264enc instead of omxh264enc in gstreamer command，because omxh264enc has been deprecated.
- 20211025
Use nvcamerasrc instead of v4l2src in gstreamer command , and the data goes directly into DMA memory.
