Use v4l2-ctl --list-formats-ext --device /dev/video42 querying device video format.
Use v4l2-ctl --streamcapture image.
v4l2-ctl -d /dev/video42 --set-fmt-video=width=1920,height=1080,pixelformat=pGAA --stream-mmap=3 --stream-to=/home/sunplus/Videos/ov5647.raw --stream-skip=9 --stream-count=1
BPI-F4:How to create an image that can use OV5647
1.Install dependency packages and tools
sudo apt-get install pv openssl libssl-dev bison flex git make u-boot-tools libmpc-dev libgmp-dev python3-pip mtd-utils libncurses5 libncurses-dev mtools -y
sudo pip install pycryptodomex pyelftools Crypto
sudo ln -s /usr/bin/python3 /usr/bin/python
2.Code download Gitee:
git clone https://gitee.com/sunplus-plus1/q654.git
or Github:
git clone https://github.com/sunplus-plus1/Q654.git
3.After the download is complete, a directory named q654 will be generated, as shown below:
Execute the following command in this directory to grab the subdirectory code:
git submodule update --init --recursive
Execute the following command to switch to the master branch:
git submodule foreach git checkout master
After the download is complete, execute the following command to view the directory file size:
du -hd 1
The directory file size should be:
4.Execute make config in the root directory of the code. The first time you run it, it will automatically download all the necessary toolchains from the Internet.
After the download is complete, the hardware platform options will be displayed, including different customer platforms and development board abbreviations.
Select as follows:
5.Enter the kernel configuration by running the following command in the top directory of project
6.Selects sub-menus: Device Drivers>Multimedia support>Media ancillary drivers>Camera sensor devices
7.Select “OmniVision OV5647 sensor support” and press “Y”. Then save and exit.
8.Device-tree source files of SP7350 are located in linux/kernel/arch/arm64/boot/dts/sunplus/ . Modify device tree source file to define OV5647 source for driver
9.After completing all configurations, you are ready to initiate the code build. Execute the following command to commence the build process:
After make command completes, it will display information similar to the following screenshot:
10.Upon completion of the build process, the resulting image files are stored in the directory. Refer to the list below:out/boot2linux_SDcard/
BPI-F4:How to use video camera ov5647
After connecting and powering on the camera module, Use v4l2-ctl --all --device /dev/video0 command getting device all information
Use v4l2-ctl -d /dev/video42 --set-ctrl params=value setting device controls.
v4l2-ctl -d /dev/video42 --set-ctrl auto_exposure=1
v4l2-ctl -d /dev/video42 --set-ctrl gain_automatic=1
v4l2-ctl -d /dev/video42 --set-ctrl white_balance_automatic=1
Use querying device video format
Use v4l2-ctl for image capture:
v4l2-ctl -d /dev/video42 --set-fmt-video=width=1920,height=1080,pixelformat=pGAA --stream-mmap=3 --stream-to=/home/sunplus/Videos/ov5647.raw --stream-skip=9 --stream-count=1```1.First, connect the OV5647 camera to the F4 board (Note: Ensure it is not connected backwards; the gold fingers must face the jumper cap).
2.Then power up and start the system. If this is your first time using the OV5647 camera, execute the following command; otherwise, you may skip this step.
sudo apt update
sudo apt install v4l-utils
3.Connect via HDMI, launch the terminal in Ubuntu desktop mode, and enter the following command to activate the OV5647 camera
ffplay -f v4l2 -i /dev/video42
The image I am using is as follows 20250730-BPI-F4-Ubuntu24.04-xfce-desktop-SD.img
my boot log is as follows BPI-F4_log ofbooting_SD.txt (60.6 KB)
