Camera Setup Instructions

Hardware Connection

  1. Connect your OS08A20 camera to the Verdin DSI/CSI to mini SAS Adapter (included in the kit) (1)
  2. Connect the adapter to the appropriate CSI interface on the carrier board
  3. Connect the Verdin DSI to HDMI Adapter to your HDMI display (1)

Software Configuration for Torizon OS

Step 1: Launch Required Containers

For camera usage with HDMI display, you need to run multiple containers (2):

Launch Weston Container for Display:

docker container run -d --name=weston --net=host \
    --cap-add CAP_SYS_TTY_CONFIG \
    -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ \
    --device-cgroup-rule="c 4:* rmw" --device-cgroup-rule="c 253:* rmw" \
    --device-cgroup-rule="c 13:* rmw" --device-cgroup-rule="c 226:* rmw" \
    --device-cgroup-rule="c 10:223 rmw" --device-cgroup-rule="c 199:0 rmw" \
    torizon/weston-imx8:4 \
    --developer

Step 2: Identify Camera Device

Check available video devices:

ls /dev/video*
v4l2-ctl --list-devices

Step 3: Launch GStreamer Container

Run GStreamer container with device access:

docker run --rm -it -v /tmp:/tmp -v /var/run/dbus:/var/run/dbus -v /dev:/dev -v /sys:/sys \
    --device /dev/<video-device> \
    --device-cgroup-rule='c 226:* rmw' --device-cgroup-rule='c 199:* rmw' \
    <your-dockerhub-username>/<Dockerfile-name>

Step 4: Camera Display Pipeline

Basic GStreamer pipeline for camera display:

gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,width=1920,height=1080 ! fpsdisplaysink text-overlay=false video-sink=waylandsink sync=false -v

Device Tree Overlay Configuration

Available Overlays

For camera functionality on Verdin iMX95, there’s a pre-built overlay available:

  • verdin-imx95_ov5640_overlay.dtbo for CSI Camera OV5640 (2)

Custom Overlay for OS08A20

Since OS08A20 is not a standard supported sensor, you’ll need to create a custom device tree overlay based on the OV5640 example but adapted for OS08A20 specifications.

MIPI CSI-2 Interface Details

The Verdin module family provides one quad-lane MIPI CSI-2 interface on reserved pins (2). Key specifications:

  • MIPI CSI-2 specification V1.3
  • MIPI D-PHY specification V1.2
  • Scalable data lane support: 1 to 4 Data Lanes
  • Performance: Up to 1.5Gbps per lane, providing 1080p60 capability with all 4 lanes

Display Configuration

HDMI Output Setup

The i.MX95 Verdin EVK supports HDMI output through the included Verdin DSI to HDMI Adapter (1). The default resolution with HDMI overlays is 1920x1080.

Graphics Capabilities

  • Graphics Controller: 3D & 2D GPU: Arm Mali-G310 V2 with 2D/3D acceleration (1)
  • Video Decoder/Encoder: Yes (1)
  • 2D/3D Acceleration: Yes (1)

Migration Path to Production

The evaluation kit provides a clear path to volume production (1):

  1. Start with the i.MX95 Verdin EVK for development and prototyping
  2. Scale to production with:
    • Verdin iMX95 SoM (Available Q2’2025)
    • Aquila iMX95 SoM (Available Q3’2025)
    • SMARC iMX95 SoM (Available Now)

Software Ecosystem Support

The i.MX95 Verdin EVK comes with comprehensive software support (1):

  • Torizon OS: Industrial Linux distribution with automotive-grade OTA updates
  • Container-first architecture: Applications run in isolated Docker containers
  • Security compliance: Helps with EU Cyber Resilience Act (CRA) requirements
  • Long-term support: Available until 2035+
