VEYE CS Camera source for Jetson
Nvidia Jetson platform VEYE and CS series camera driver source code compilation guide
1 Overview
1.1 Jetpack version VS. L4T version
- 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
- Jetpack4.5.1,L4T r32.5.1
1.2 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
2 Setting Up the Host PC Environment
The following operations are done in HOST PC.
- Cross-compiling Toolchain
Please refer to this link to install toolchain on your Host PC.
- L4T source code and Rootfs
Please download the Linux_for_Tegra SDK via SDK Manager first.
You could use SDK Manager or directly download to get source code.
Sync code as this if you use SDK Manager:
- Jetpack4.2.2
./source_sync.sh -t tegra-l4t-r32.2.1
- Jetpack4.3
./source_sync.sh -t tegra-l4t-r32.3.1
- Jetpack4.4
./source_sync.sh -t tegra-l4t-r32.4.3
- Jetpack4.4.1
./source_sync.sh -t tegra-l4t-r32.4.4
- Jetpack4.5
./source_sync.sh -t tegra-l4t-r32.5
- Jetpack4.5.1
./source_sync.sh -t tegra-l4t-r32.5.1
- Jetpack4.5.1
./source_sync.sh -t tegra-l4t-r32.5.1
- Setting Up the Environment
Assume SDK install directory is <TOPDIR>,source code is in $L4T_DIR/sources directory.
export TOP_DIR=<absolute path to top dir accroding to your jetpack version and board name;for example /home/xumm/nvidia/nvidia_sdk/JetPack_4.5_Linux_JETSON_XAVIER_NX_DEVKIT/>
export L4T_DIR=$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 NANO_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t210/
export TX2_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t18x

3 Download our 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
4 Build kernel
4.1 patch code
cp $RELEASE_PACK_DIR/drivers_source/cam_drv_src/* $NVIDIA_PATH/drivers/media/i2c/
cp $RELEASE_PACK_DIR/drivers_source/kernel_veyecam_config_<l4t_version> $L4T_DIR/sources/kernel/kernel-4.9/arch/arm64/configs/tegra_veyecam_defconfig
4.2 build
cd $L4T_DIR/sources/kernel/kernel-4.9/
make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_veyecam_defconfig
make ARCH=arm64 O=$TEGRA_KERNEL_OUT Image -j4
Completed Image file is $TEGRA_KERNEL_OUT/arch/arm64/boot/Image,could be used for Flashing or Upgrading.
Install Image for Flashing:
sudo cp $TEGRA_KERNEL_OUT/arch/arm64/boot/Image $L4T_DIR/kernel/ -f
- For xavier,need sign the file
cd $L4T_DIR
./l4t_sign_image.sh --file kernel/Image --chip 0x19
