Intel® RealSense™ camera driver for GMSL* interface

D457 MIPI on Jetson AGX Xavier

The RealSense MIPI platform driver enables the user to control and stream RealSense 3D MIPI cameras. The system shall include:

Jetson platform (Currently Supported JetPack versions are: 6.0, 5.1.2, 5.0.2, 4.6.1)
RealSense De-Serialize board (https://store.intelrealsense.com/buy-intel-realsense-des457.html)
RS MIPI camera (e.g. https://store.intelrealsense.com/buy-intel-realsense-depth-camera-d457.html)

Note: This MIPI reference driver is based on RealSense de-serialize board. For other de-serialize boards, modification might be needed.

Jetson AGX Xavier board setup

Please follow the instruction to flash JetPack to the Jetson AGX Xavier with NVIDIA SDK Manager or other methods NVIDIA provides. Make sure the board is ready to use.

Build kernel, dtb and D457 driver

The developers can set up the source code with NVIDIA's Jetson git repositories by using the provided setup script:

# Using setup script, recommended for developers. If JetPack version is not given, default version will be chosen.
./setup_workspace.sh [JetPack_version]

Apply D457 patches and build the kernel image, dtb and D457 driver.

# if using setup script
./apply_patches.sh [--one-cam | --dual-cam] apply [JetPack_version]

# or, if using direct download method
# ./apply_patches_ext.sh [--one-cam | --dual-cam] ./Linux_for_tegra/source/public [JetPack_version]
# for JP6.0, source path is ./Linux_for_tegra/source :
# ./apply_patches_ext.sh ./Linux_for_tegra/source 6.0

Note: The `--one-cam` and `--dual-cam` option applies only for JetPack 5.0.2,
compatible with adapter: https://store.intelrealsense.com/buy-intel-realsense-des457.html.
By setting the `--one-cam` option it builds DT with only camera on GMSL link A (default).
By setting the `--dual-cam` option it builds DT with dual cameras on GMSL link A and B.
The default is to single camera configuration for JetPack 5.0.2.

# build kernel, dtb and D457 driver
# install dependencies
sudo apt install build-essential bc flex bison
# method 1: build kernel Debian packages
./build_all_deb.sh [--no-dbg-pkg] [JetPack_version] [JetPack_source_dir]
# method 2: build kernel and modules only
./build_all.sh [JetPack_version] [JetPack_source_dir]

# remove our patches from JetPack kernel source code if using setup script
# ./apply_patches.sh reset [JetPack_version]

Debian packages will be generated in images folder.

Install kernel and D457 driver to Jetson Orin

JP6.0 build results

dtb overlay: images/6.0/rootfs/boot/tegra234-camera-d4xx-overlay.dtbo
oot modules: images/6.0/rootfs/lib/modules/5.15.122-tegra/extra

Following steps required:

sudo cp videodev.ko /lib/modules/5.15.122-tegra/kernel/drivers/media/v4l2-core/videodev.ko
# backup kernel (better to have additional boot entry in extlinux.conf)
sudo cp /boot/Image /boot/Image.orig
sudo cp Image /boot/Image

Enable d4xx overlay:

With Jetson-IO tool: sudo /opt/nvidia/jetson-io/jetson-io.py

Configure Jetson AGX CSI Connector
Configure for compatible hardware
Jetson RealSense Camera D457

With command line

sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="Jetson RealSense Camera D457"

Expected:

nvidia@ubuntu:~$ sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="Jetson RealSense Camera D457"
Configuration saved to /boot/tegra234-camera-d4xx-overlay.dtbo.
Reboot system to reconfigure.

Enable d4xx autoload:

echo "d4xx" | sudo tee /etc/modules-load.d/d4xx.conf

sudo depmod

Install kernel and D457 driver to Jetson AGX Xavier

Install the kernel and modules

1.1 If building with build_all_deb.sh

Copy the Debian package linux-image-5.10.104-d457_5.10.104-d457-1_arm64.deb to the Jetson AGX Xavier board and install with sudo dpkg -i linux-image-5.10.104-d457_5.10.104-d457-1_arm64.deb. The header, libc-dev, dbg and firmware packages are optional.

1.2 If building with build_all.sh

The necessary files are:

kernel image images/<JetPack_version>/arch/arm64/boot/Image
dtb images/<JetPack_version>/arch/arm64/boot/dts/nvidia/tegra194-p2888-0001-p2822-0000.dtb, or images/4.6.1/arch/arm64/boot/dts/tegra194-p2888-0001-p2822-0000.dtb for JetPack 4.6.1.
D457 driver images/<JetPack_version>/drivers/media/i2c/d4xx.ko
UVC Video driver images/<JetPack_version>/drivers/media/usb/uvc/uvcvideo.ko
V4L2 Core Video driver images/<JetPack_version>/drivers/media/v4l2-core/videobuf-core.ko
V4L2 VMalloc Video driver images/<JetPack_version>/drivers/media/v4l2-core/videobuf-vmalloc.ko

And copy them to the right places:

sudo cp Image /boot
sudo cp tegra194-p2888-0001-p2822-0000.dtb /boot/dtb
sudo cp d4xx.ko /lib/modules/5.10.104-tegra/kernel/drivers/media/i2c/
sudo cp uvcvideo.ko /lib/modules/5.10.104-tegra/kernel/drivers/media/usb/uvc/
sudo cp videobuf-core.ko /lib/modules/5.10.104-tegra/kernel/drivers/media/v4l2-core/
sudo cp videobuf-vmalloc.ko /lib/modules/5.10.104-tegra/kernel/drivers/media/v4l2-core/
sudo depmod

Edit /boot/extlinux/extlinux.conf primary boot option's LINUX/FDT lines to use built kernel image and dtb file:

LINUX /boot/Image-5.10.104-d457
FDT /usr/lib/linux-image-5.10.104-d457/tegra194-p2888-0001-p2822-0000.dtb

Make D457 I2C module autoload at boot time: echo "d4xx" | sudo tee /etc/modules-load.d/d4xx.conf

After rebooting Jetson, the D457 driver should work.

NOTE

Each JetPack version's kernel may be different, the user needs to change the kernel version in file names and paths accordingly, for example for JetPack 4.6.1 the version is 4.9.253-d457 or 4.9.253-tegra, depending on the build method applied.
For JetPack 4.6.1, the dtb file is not included in the deb package. User needs to manually copy images/4.6.1/arch/arm64/boot/dts/tegra194-p2888-0001-p2822-0000.dtb file to board and edit extlinux.conf to point to it.
It's recommended to save the original kernel image as backup boot option in /boot/extlinux/extlinux.conf.
