Sony IMX586 – V4L2 Driver for NVIDIA Jetson (4-lane CSI)

Linux V4L2 sub-device driver for Sony IMX586 integrated into Jetson platforms with 4-lane CSI interfaces.

Supported Jetson Boards

Jetson Model	Interface	Notes
Nano (B01)	CSI A/B	Dual 2-lane, use B for 4-lane
Xavier NX	CSI A/B	Both support 4 lanes
TX2 NX	CSI	4-lane supported
AGX Xavier	CSI	6-lane total (3x2 or 2x4)
Orin NX / Nano	CSI	Up to 4-lane supported

Sensor Integration

I²C and GPIO

Signal	Value
I²C addr	0x1a (7-bit)
RESET	GPIO (board DT specific)
XCLK	37.125 MHz
DOVDD	1.8 V
AVDD	2.8 V
DVDD	1.1 V (on-chip LDO)

Set appropriate regulators and clocks in DTSI according to carrier board.

};

Driver Installation

sudo apt install dkms build-essential
./setup.sh

Then rebuild and flash DT to integrate the .dtsi. This is platform-specific (flash.sh, JetPack SDK, etc.).

libcamera / V4L2 Use

Check detection:

v4l2-ctl --list-devices

Stream test:

libcamera-vid -t 0 --width 4000 --height 3000 --framerate 30 -o out.h264

Notes

• Use correct CSI interface index (serial_a, serial_b, etc.)
• Modify GPIO and regulator entries to match carrier board layout.
• Driver supports IMX586 QBC 12MP @30fps. Add modes in reg_tables.h.

TODO

• Add 4K60 and HDR modes
• Full libcamera tuning support
• C-PHY mode support (future Jetsons only)
