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.

• 2-lane and 4-lane MIPI CSI-2
• 12-bit RAW output
• 3856×2180 (full resolution)
• 1928×1090 (2×2 binned)
• 25 fps on 4 lanes, 12.5 fps on 2 lanes

Note

Bring-up release runs both modes at conservative 720 Mbps/lane, which caps frame rate at 25 fps on 4 lanes. 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 overlays (.dtbo) to /boot

Use Jetson-IO to configure CSI connector:

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 port configuration:

   • Camera IMX585-A - cam0 (2-lane)
   • Camera IMX585-C - cam1 (4-lane)

   

4. Save pin changes

5. Save and reboot to reconfigure pins

After reboot, verify sensor is detected:

sudo dmesg | grep imx585

Expected output:

nv_imx585: module verification failed: signature and/or required key missing - tainting kernel
imx585 9-001a: tegracam sensor driver:imx585_v2.0.6
tegra-camrtc-capture-vi tegra-capture-vi: subdev imx585 9-001a bound

Signature warning is expected since DKMS modules are unsigned.

Image output

Mode	Resolution	Readout
0	3856×2180	Full native array
1	1928×1090	2×2 binned

GStreamer

   'video/x-raw(memory:NVMM),width=3856,height=2180,framerate=25/1' ! \

On cam0, use framerate=12/1.

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 overlays
make module    # build only the kernel module
make clean     # remove build artifacts

Build artifacts are placed in ./build.
