VEYE CS Camera on Firfly Boards
How to use VEYE and CS series cameras on Firefly's RK35XX board (Ubuntu)
1 Overview
VEYE series and CS series cameras are the video streaming mode MIPI cameras we designed. This article takes Firefly's ROC-RK3566-PC board as an example to introduce how to connect VEYE and CS series cameras to RK3566/RK3568/RK3588 system.
1.1 Camera Module List
Series | Model | Status |
---|---|---|
VEYE Series | VEYE-MIPI-IMX327S | Done |
VEYE Series | VEYE-MIPI-IMX462 | Done |
VEYE Series | VEYE-MIPI-IMX385 | Done |
2 Hardware Setup
VEYE series and CS series cameras are provided with Raspberry Pi compatible 15Pin FFC connector. An ADP-Tfirefly adapter board is required to adapt to the ROC-RK3566-PC board.
2.1 Connection of camera and ADP-Tfirefly
The two are connected using 1.0 mm pitch*15P FFC cable with opposite direction. The cable must be inserted with the silver contacts facing outside.
2.2 Connection of ADP-Tfirefly and Firefly Board
The two are connected using 0.5 mm pitch*30P FFC cable with same direction. The cable must be inserted with the silver contacts facing inside.
2.3 Overall connection
3 Introduction to github repositories
https://github.com/veyeimaging/rk356x_firefly
includes:
- driver source code
- i2c toolkits
- application demo
In addition, a compiled linux kernel installation package is provided in the releases.
4 Upgrade Firefly Ubuntu system
4.1 Overview
This section describes how to update the RK35xx system to support our camera modules.
For some versions, we provide a deb installer that can be installed directly. For versions where no installer is provided, you will need to refer to later chapters to compile from the driver source code.
Although we are now using Ubuntu system as an example to introduce, other Linux distributions can also refer to this article.
4.2 Burn Firefly standard system
Refer to the Firefly documentation to burn in a standard system.
4.3 Using prebuilt Image and dtb file
Using the compiled debain installation package
On the RK35xx board, execute :
wget https://github.com/veyeimaging/rk356x_firefly/releases/latest/download/rk356x_firefly.tar.gz
tar -xavf rk356x_firefly.tar.gz
cd cd rk356x_firefly/released_images/ROC-RK3566-PC/ubuntu/
sudo dpkg -i linux-image-4.19.232_4.19.232-21_arm64.deb
If the version does not match, it needs to be compiled from the source code.
5 Check system status
Run the following command to confirm whether the camera is probed.
- VEYE-MIPI-XXX
dmesg | grep veye
The output message appears as shown below:
veyecam2m 4-003b: camera id is veyecam2m
veyecam2m 4-003b: sensor is IMX327
- Run the following command to check the presence of video node.
ls /dev/video0
The output message appears as shown below.
video0
The camera can be seen connected to the i2c-4.
