How to use VEYE and CS series cameras on Firefly's RK35XX board
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 and ROC-RK3588S-PC board as an example to introduce how to connect VEYE and CS series cameras to RK3566/RK3568/RK3588 system.
We provide drivers for both Linux(Ubuntu) and Android.
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 |
In addition, the driver for the Fpdlink connection mode has been finished on the Ubuntu system.
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-RK35xx-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.

3 Introduction to github repositories
https://github.com/veyeimaging/rk35xx_veye_bsp
https://github.com/veyeimaging/rk35xx_firefly
includes：
- driver source code
- i2c toolkits
- application demo
In addition, a compiled linux kernel installation package and Android image is provided in the releases.
4 Ubuntu
4.1 Upgrade Firefly Ubuntu system（RK356x）
4.1.1 Overview
This section describes how to update the RK35xx system to support our camera modules.
For the kernel version 4.19, we provide a deb installation package that can be installed directly.
For the kernel version 5.10, we provide a burning image.
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.
4.1.2 kernel version 5.10
For the ROC-RK3588S-PC, we have provided an image of the release system.
Download the latest released image file corresponding to the camera model you are using from https://github.com/veyeimaging/rk35xx_firefly/releases/ .
Refer to the Firefly documentation to burn in a standard system.
4.1.3 kernel version 4.19
4.1.3.1 Burn Firefly standard system
Refer to the Firefly documentation to burn in a standard system.
4.1.3.2 Using prebuilt Image and dtb file
Using the compiled debain installation package
On the RK35xx board,
Download the latest rk356x_firefly_ubuntu.tar.gz from https://github.com/veyeimaging/rk35xx_firefly/releases/ .
tar -xavf rk356x_firefly.tar.gz
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.
4.2 Upgrade Firefly Ubuntu system（RK358x）
For the ROC-RK3588S-PC, we have provided an image of the release system.
Download the latest released image file corresponding to the camera model you are using from https://github.com/veyeimaging/rk35xx_firefly/releases/ .
Refer to the Firefly documentation to burn in a standard system.
4.3 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
For ROC-RK3566-PC, the camera is connected to i2c-4, for ROC-RK3588S-PC to i2c-7.
4.4 Application examples
4.4.1 v4l2-ctl
4.4.1.1 Install v4l2-utils
sudo apt-get install v4l-utils
4.4.1.2 List the data formats supported by the camera
v4l2-ctl --list-formats-ext
4.4.1.3 Snap YUV picture
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat='NV12' --stream-mmap --stream-count=100 --stream-to=nv12-1920x1080.yuv
For RK3566, also:
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --stream-mmap --stream-count=1 --stream-to=uyvy-1920x1080.yuv
Play YUV picture
ffplay -f rawvideo -video_size 1920x1080 -pix_fmt nv12 nv12-1920x1080.yuv
4.4.1.4 Check frame rate
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --stream-mmap --stream-count=-1 --stream-to=/dev/null
4.4.2 yavta
git clone https://github.com/veyeimaging/yavta.git
cd yavta;make
./yavta -c1 -Fnv12-1920x1080.yuv --skip 0 -f NV12 -s 1920x1080 /dev/video0
4.4.3 gstreamer
We provide several gstreamer routines that implement the preview, capture, and video recording functions. See the samples directory on github for details.
4.4.4 Import to OpenCV
First install OpenCV:
sudo apt install python3-opencv
We provide several routines to import camera data into opencv. See the samples directory on github for details.
In addition, this page from Firefly has some reference value.
4.5 Compile drivers and dtb from source code
- RK356x
https://github.com/veyeimaging/rk35xx_firefly/tree/main/linux/drivers/rk356x
- RK358x
https://github.com/veyeimaging/rk35xx_firefly/tree/main/linux/drivers/rk358x
5 i2c script for parameter configuration
Because of the high degree of freedom of our camera parameters, we do not use V4L2 parameters to control, but use scripts to configure parameters.
