IMX585 kernel driver for NVIDIA Jetson

NVIDIA Jetson kernel driver for Sony IMX585, an 8.3 MP STARVIS 2 back-side illuminated CMOS sensor optimised for low-light and 4K applications.

• 4-lane MIPI CSI-2
• 12-bit RAW output
• 3856×2180 (full resolution) @ 25 fps
• 1928×1090 (2×2 binned) @ 25 fps

Note

Bring-up release runs both modes at conservative 720 Mbps/lane, which caps frame rate at 25 fps. Higher link rates, ClearHDR and mono support are planned.

IMX585 camera modules are available at kurokesu.com

Setup

Install required tools:

sudo apt install -y --no-install-recommends dkms

Clone this repository:

cd ~
git clone https://github.com/Kurokesu/imx585-jetson-driver.git
cd imx585-jetson-driver/

Run setup script:

sudo ./setup.sh

Setup script:

• Fetches NVIDIA device tree headers required for build
• Builds and installs kernel module via DKMS
• Builds and copies device tree overlay (.dtbo) to /boot

Use Jetson-IO to configure the CSI connector:

Note

IMX585 requires 4-lane MIPI CSI, so only port C (cam1) is supported.

sudo /opt/nvidia/jetson-io/jetson-io.py

Navigate through the menu:

1. Configure Jetson CSI Connector (named "22pin" on 6.2.2, "24pin" on 6.2.1)
2. Configure for compatible hardware
3. Select Camera IMX585-C

4. Save pin changes
5. Save and reboot to reconfigure pins

After reboot, verify sensor is detected:

sudo dmesg | grep imx585

Test mode

IMX585 has a built-in test pattern generator for verifying data validity.

Enable test pattern:

# Horizontal color-bar test pattern (test_mode = 5)
echo 5 | sudo tee /sys/module/nv_imx585/parameters/test_mode

Turn test pattern off:

echo 0 | sudo tee /sys/module/nv_imx585/parameters/test_mode

Test pattern code	Description
0	Off (normal operation)
1	All 000h
2	All FFFh
3	All 555h
4	All AAAh
5	Horizontal color bars
6	Vertical color bars

Development builds

For manual builds without DKMS:

make              # build everything (dtbo + kernel module)
sudo make install # copy dtbo to /boot, rmmod + insmod

Note

Module is loaded immediately via insmod but won't persist across reboots. Use sudo ./setup.sh for permanent installation via DKMS.

Individual targets:

make dtbo      # build only the device tree overlay
make module    # build only the kernel module
make clean     # remove build artifacts

Build artifacts are placed in ./build.
