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

1 Overview

This guide shows how to use VEYE and CS series camera modules on Jetson TX2 and AGX Xavier. Jetson JetPack SDK Version is r32.2.1. We provide two ways to do so: Prebuilt Binaries or Source Code. Yes, It's Open Source!

VEYE and CS series camera modules are STARVIS 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

2.1 NVIDIA TX2 Developer Kit

We have designed a special adapter board for TX2 developwer kit, It support up to 6 cameras at the same time.

It is connected as shown in figure (TODO).

3 Upgrade Jetson TX2 and AGX Xavier system

3.1 Setting Up the Host PC Environment

• Cross-compiling Toolchain

Please refer to this link to install toolchain on your Host PC.

• L4T source code and Rootfs

You could use SDK Manager or directly download to get source code.

Sync code as this if you use SDK Manager:

./source_sync.sh -t tegra-l4t-r32.2.1

• Setting Up the Environment

Assume SDK install directory is <TOPDIR>，source code is in $L4T_DIR/sources directory.

- TX2

export TOP_DIR=/home/xumm/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P3310/

- AGX Xavier

export TOP_DIR=/home/xumm/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P2888/

export L4T_DIR=$TOP_DIR/Linux_for_Tegra

export LOCALVERSION=-tegra

export LDK_ROOTFS_DIR=$TOP_DIR/Linux_for_Tegra/rootfs

export ARCH=arm64

export CROSS_COMPILE=aarch64-linux-gnu-

export CROSS32CC=arm-linux-gnueabihf-gcc

export TEGRA_KERNEL_OUT=$L4T_DIR/sources/kernel/out_kernel

export KERNEL_PATH=$L4T_DIR/sources/kernel/out_kernel

export NVIDIA_PATH=$L4T_DIR/sources/kernel/nvidia

export TX2_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t18x

export XAVIER_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t19x

cd $L4T_DIR/sources/kernel/kernel-4.9/

• Build default image, flashing to Jetson Board, prepare L4T environment

cd $L4T_DIR

sudo ./apply_binaries.sh  

- TX2

sudo ./flash.sh jetson-tx2 mmcblk0p1

- AGX Xavier

sudo ./flash.sh jetson-xavier mmcblk0p1

3.2 Download out bsp package for Jetson

cd $L4T_DIR

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

export RELEASE_PACK_DIR=$L4T_DIR/nvidia_jetson_veye_bsp

3.2.1 bsp package includes：

• prebuild linux kernel：Image
• prebuild dtb for different boards
• driver source code
• dts source code
• i2c toolkits

3.3 Using prebuild Image and DTB

• Installing the Kernel

Whether you use a prebuild kernel or you build it yourself

- TX2

copy Image to /boot/ dir on the Jetson TX2 board:

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

- AGX Xavier

on the Host PC:

cd $L4T_DIR

sudo ./flash.sh -k kernel jetson-xavier mmcblk0p1

• Flashing dtb file

Enter the recovery mode，and on the Host PC:

cp <path to your dtb dir>/dtbfilename $L4T_DIR/kernel/dtb/ -f

cd $L4T_DIR

- TX2

sudo ./flash.sh -r -k kernel-dtb jetson-tx2 mmcblk0p1

- AGX Xavier

sudo ./flash.sh -r -k kernel-dtb jetson-xavier mmcblk0p1

Reset Jetson Board after flashing.

3.4 Building from Source

3.4.1 Build kernel

• patch code

cp $RELEASE_PACK_DIR/drivers_source/cs_imx307\ veye327/* $NVIDIA_PATH/drivers/media/i2c/

cp $RELEASE_PACK_DIR/drivers_source/kernel_csimx307veye327_config $L4T_DIR/sources/kernel/kernel-4.9/arch/arm64/configs/tegra_csimx307veye327_defconfig

5 Realtimes RTSO-9001

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.
