NVIDIA has released Linux developer guide for each Jetpack version. For example, L4T [https://docs.nvidia.com/jetson/archives/r35.1/DeveloperGuide/index.html 35.1] and [https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-325/#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/kernel_custom.html# 32.5].

This section is based on the official Kernel Customization section, so please refer to the official documentation for any lack of detail.

Nvidia Jetson platform VEYE camera driver source code compilation guide

1 Overview

NVIDIA has released Linux developer guide for each Jetpack version. For example, L4T 35.1 and 32.5.

This section is based on the official Kernel Customization section, so please refer to the official documentation for any lack of detail.

We use a host pc with Ubuntu installed and a Jetson board as our development environment.

  • Jetpack 4.x

driver is compiled together with the linux kernel on the host pc. dtb is also compiled on the host pc.

  • Jetpack5.x

The driver is compiled to modules, on the Jetson board. dtb compilation is done on the host pc.

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
  • Jetpack4.6, L4T r32.6.1
  • Jetpack4.6.1, L4T r32.7.1
  • Jetpack4.6.2, L4T r32.7.2
  • Jetpack4.6.3, L4T r32.7.3
  • Jetpack5.0.1DP,L4T r34.1.1
  • Jetpack5.0.2, L4T r35.1
  • Jetpack5.1, L4T r35.2.1
  • Jetpack5.1.1, L4T r35.3.1
  • Jetpack5.1.2, L4T r35.4.1
  • Jetpack5.1.3, L4T r35.5

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 Set up the Host PC environment

The following operations are done in HOST PC.

2.1 Cross-compiling Toolchain

  • Jetpack4.xPlease refer to this link to install toolchain on your Host PC.
  • Jetpack5.x

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

2.2 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. I recommend the direct download method.

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

- Jetpack4.6

./source_sync.sh -t tegra-l4t-r32.6.1

- Jetpack4.6.1

./source_sync.sh -t tegra-l4t-r32.7.1

- Jetpack4.6.2

Nvidia did not push sources to nv-tegra for this 32.7.2 release because there have been no changes in the kernel and DTS compared to 32.7.1 release.

- Jetpack5.0.1 DP

./source_sync.sh -t jetson_34.1.1

- Jetpack5.0.2

./source_sync.sh -t jetson_35.1

- Jetpack5.1

./source_sync.sh -t jetson_35.2.1

- Jetpack5.1.1

./source_sync.sh -t jetson_35.3.1

- Jetpack5.1.2

./source_sync.sh -t jetson_35.4.1

- Jetpack5.1.3

./source_sync.sh -t jetson_35.5

2.3 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 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

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

export COMMON_DTS_PATH=$TEGRA_KERNEL_OUT/arch/arm64/boot/dts/

  • Jetpack 4.x only

export CROSS_COMPILE=aarch64-linux-gnu-

export CROSS32CC=arm-linux-gnueabihf-gcc

  • Jetpack 5.x only

export CROSS_COMPILE_AARCH64_PATH=$HOME/l4t-gcc

export CROSS_COMPILE_AARCH64=$HOME/l4t-gcc/bin/aarch64-buildroot-linux-gnu-

export CROSS_COMPILE=$CROSS_COMPILE_AARCH64

export COMMON_DTS_PATH=$TEGRA_KERNEL_OUT/arch/arm64/boot/dts/nvidia

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

For Jetpack version 4.x and for using MV series cameras under Jetpack version 5.x, the kernel needs to be compiled.

4.1 kernel patch for MV series

For MV series camera, besides adding the camera driver in Linux system, we also add a kernel patch - veye_mv_l4t_[version].patch.

This patch has two features：

  1. Added support for both Y10 and Y12 data formats for Mono cameras.
  2. Added support for trigger mode.

This patch package can be left out for VEYE series and CS series cameras.

cd $L4T_DIR/sources/kernel/

patch -p1 < [path to]veye_mv_l4t_[version].patch

4.2 For Jetpack 4.x, the camera driver is compiled into the Image

4.2.1 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

4.2.2 Modify Kconfig and Makefile

Modify the Kconfig and Makefile files under the $NVIDIA_PATH/drivers/media/i2c/ directory to add the corresponding camera driver compilation options.

4.2.3 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

4.3 For Jetpack 5.x, there is no need to compile the camera driver into the Image

4.3.1 build

cd $L4T_DIR/sources/

./nvbuild.sh -o $TEGRA_KERNEL_OUT

nvbuild.sh is only included in the kernel_src.tbz2 tar file that is part of public_sources.tbz2. If the kernel sources were synced from the Git server, you need to manually copy nvbuild.sh from the tar file.

4.4 Build completed

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 and Orin，need sign the file

cd $L4T_DIR

./l4t_sign_image.sh --file kernel/Image --chip 0x19

5 Build modules(Jetpack5.x)

For version later than Jetpack 5.x, can compile the driver directly as modules to get the ko file. It is recommended to compile the driver directly on Jetson Board.

cd $RELEASE_PACK_DIR/drivers_source/cam_drv_src/

make -f Makefile
