RealSense™ camera driver for GMSL* interface

D457 MIPI on NVIDIA® Jetson AGX Orin™ JetPack 6.x

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

NVIDIA® Jetson™ platform Supported JetPack versions are:
RealSense™ De-Serialize board
Jetson AGX Orin™ Passive adapter board from Leopard Imaging® LI-JTX1-SUB-ADPT
RS MIPI camera D457

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

NVIDIA® Jetson AGX Orin™ board setup

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

Build environment prerequisites

sudo apt-get install -y build-essential bc wget flex bison curl libssl-dev xxd tar

Build NVIDIA® kernel drivers, dtb and D457 driver

Clone realsense_mipi_platform_driver repo.
The developers can set up build environment, ARM64 compiler, kernel sources and NVIDIA's Jetson git repositories by using the setup script.
Apply patches for kernel drivers, nvidia-oot module and tegra devicetree.
Build project
Apply build results to target (Jetson).
Configure target.

Assuming building for 6.2. One can also build for 6.1, 6.0 just replace the last parameter.

git clone --branch dev --single-branch https://github.com/realsenseai/realsense_mipi_platform_driver.git
cd realsense_mipi_platform_driver
./setup_workspace.sh 6.2
./apply_patches.sh 6.2
./build_all.sh 6.2

Note: dev_dbg() log support will not be enabled by default. If needed, run the ./build_all.sh script with --dev-dbg option like below.

./build_all.sh --dev-dbg 6.2

JetPack manual build - cross compile x86-64 (CI deploy)

NVIDIA® JetPack 6.2: Jetson Linux 36.4.3

Download Jetson Linux Driver Package - JetPack 6.2 BSP sources
Download Toolchain ARM64 compiler - Bootlin Toolchain gcc 11.3

Archive JetPack 6.x build results (optional)

Assuming 6.2 (or 6.1) build the kernel version is 5.15.148-tegra. For 6.0 the kernel version is 5.15.136-tegra.

kernel image : images/6.2/rootfs/boot/Image
dtb: images/6.2/rootfs/boot/dtb/tegra234-p3737-0000+p3701-0000-nv.dtb
dtb overlay: images/6.2/rootfs/boot/tegra234-camera-d4xx-overlay.dtbo
dtb dual camera overlay: images/6.2/rootfs/boot/tegra234-camera-d4xx-overlay-dual.dtbo
kernel modules: images/6.2/rootfs/lib/modules/5.15.148-tegra

Backup JetPack 6.2 boot configuration and drivers (optional)

echo "Backup boot configuration"
sudo cp /boot/tegra234-p3737-0000+p3701-0000-nv.dtb /boot/tegra234-p3737-0000+p3701-0000-nv-bkp.dtb
# Note: If using a production board and not a dev kit copy the relevant dtb file below
sudo cp /boot/tegra234-p3737-0000+p3701-0005-nv.dtb /boot/tegra234-p3737-0000+p3701-0005-nv-bkp.dtb

Install kernel drivers, extra modules and device-tree to Jetson AGX Orin

Following steps required:

Create "dev" directory in boot (in order to not override the default kernel)

sudo mkdir /boot/dev

Copy build artifacts: If you build locally use those commands:

sudo cp -r ./images/6.2/rootfs/lib/modules/5.15.148-tegra /lib/modules/.
sudo cp    ./images/6.2/rootfs/boot/tegra234-camera-d4xx-overlay*.dtbo /boot/dev/.
sudo cp    ./images/6.2/rootfs/boot/dtb/tegra234-p3737-0000+p3701-0000-nv.dtb /boot/dtb/.
sudo cp    ./images/6.2/rootfs/boot/Image /boot/dev/.

In case of scp copy from host use this commands:

tar xf rootfs.tar.gz
sudo rm -r  /lib/modules
sudo cp -r ./lib/modules/ /lib/
sudo cp    ./boot/tegra234-camera-d4xx-overlay*.dtbo /boot/dev/.
sudo cp    ./boot/dtb/tegra234-p3737-0000+p3701-0000-nv.dtb /boot/dtb/.
sudo cp    ./boot/Image /boot/dev/.

Run depmod

sudo depmod
sudo update-initramfs -uk 5.15.148-tegra
sudo rm -f /boot/initrd
sudo ln -s /boot/initrd.img-5.15.148-tegra /boot/initrd

Modify bootloader configuration:

open /boot/extlinux/extlinux.conf for editing using your preferred editor
Copy existing primary kernel and rename the copy to "dev"
Change the "MENU LABEL" to a meaningful label (e.g "development kernel")
Change the "LINUX" line to point to the newly copied /boot/dev/Image
Add the "FDT" line pointing at the newly copied device tree "/boot/dtb/tegra234-p3737-0000+p3701-0000-nv.dtb"
add the "OVERLAYS" line pointing to the required overlay "tegra234-camera-d4xx-overlay/dual/else>.dtb
Select the new label as the default

The result should be:

...
DEFAULT dev

LABEL primary
    MENU LABEL primary kernel
    LINUX /boot/Image
    INITRD /boot/initrd
    APPEND ${cbootargs} root=...

LABEL dev
    MENU LABEL development kernel
    LINUX /boot/dev/Image
    INITRD /boot/initrd
    APPEND ${cbootargs} root=...
    FDT /boot/dtb/tegra234-p3737-0000+p3701-0000-nv.dtb
    OVERLAYS /boot/dev/tegra234-camera-d4xx-overlay.dtbo

reboot

sudo reboot

# Make sure which Jetson Carrier board is used:
#   p3701-0000 → Dev kit carrier board
#   p3701-0005 → Production carrier board or custom carrier
# if you have the *0005* board, replace the relevant dtb file in in the instructions above

Example: 
sudo cat /proc/device-tree/compatible

Output:
nvidia,p3701-0000

Notes

With the introduction of meta data support for depth IR starting from release r/1.0.1.27, calibration format streaming requires a separate DTB that disables meta data since the camera does not metadata in calibration mode.
If calibration is needed, it's recommended to add d457_calib boot option as shown below.

To generate tegra234-camera-d4xx-overlay.calib.dtbo and tegra234-camera-d4xx-overlay-dual.calib.dtbo on the Host build system, replace the contents of the below files: tegra234-camera-d4xx-overlay.dts by the contents of tegra234-camera-d4xx-overlay.calib.dts

tegra234-camera-d4xx-overlay-dual.dts by the contents of tegra234-camera-d4xx-overlay-dual.calib.dts
Reset and reapply patches and rebuild driver:

./apply_patches.sh 6.2 reset

./apply_patches.sh 6.2

./build_all.sh 6.2

Deploy 2 DTBO files on the Jetson:
In ./images/6.2/rootfs/boot/ folder, locate and rename the following DTBO files:
- Rename tegra234-camera-d4xx-overlay.dtbo to tegra234-camera-d4xx-overlay.calib.dtbo
- Rename tegra234-camera-d4xx-overlay-dual.dtbo to tegra234-camera-d4xx-overlay-dual.calib.dtbo
Copy the two DTBO files from the build Host to /boot/ on the Jetson.
