=====mv camera entity information=====
 
−
Taking the MV-MIPI-IMX296M as an example:
 
−
 
−
<code>- entity 63: m00_b_mvcam 2-003b (1 pad, 1 link)</code>
 
−
 
−
<code>             type V4L2 subdev subtype Sensor flags 0</code>
 
−
 
−
<code>             device node name /dev/v4l-subdev2</code>
 
−
 
−
<code>        pad0: Source</code>
 
−
 
−
<code>                [fmt:Y8_1X8/1456x1088@100/6000 field:none]</code>
 
−
 
−
<code>                -> "rockchip-csi2-dphy0":0 [ENABLED]</code>
 
−
 
−
You can see that:
 
−
 
−
*The complete name of this entity is: <code>m00_b_mvcam 2-003b</code>.
 
−
*It is a V4L2 subdev (Sub-Device) Sensor.
 
−
*Its corresponding node is <code>/dev/v4l-subdev2</code>, which can be opened and configured by applications (such as <code>v4l2-ctl</code>).
 
−
*Its output format is <code>[fmt:Y8_1X8/1456x1088@100/6000 field:none]</code>, where <code>Y8_1X8</code> is a shorthand for a mbus-code, which will be listed in the next section of this article.
 
−
*The current resolution is <code>1456x1088</code>.
 
−
*The current frame interval is <code>100/6000</code>, which means the frame rate is 60.
 
−
*The data format output by the camera can be modified using the media-ctl command.

===Raw data format===
 
−
The VICAP module of RK35xx supports two data saving formats, Compact and Noncompact RAW. You can modify the mode using the RKCIF_CMD_SET_CSI_MEMORY_MODE ioctl command of RKCIF. By default, the output is in Compact RAW format.[[File:Compact raw and noncompact raw of rk3588 vicap.png|center|thumb|800x800px|Compact raw and noncompact raw of rk3588 VICAP|link=http://wiki.veye.cc/index.php/File:Compact_raw_and_noncompact_raw_of_rk3588_vicap.png]]
 
−
====Noncompact RAW====
 
−
For pixel data with 10-bit depth or 12-bit depth, two bytes are always used to store one pixel. This storage method is convenient for software processing, but it has the disadvantage of occupying a large amount of space.
 
−
 
−
Depending on whether the effective data is stored in the high bits or low bits, it can be further divided into two types: high align and low align.
 
−
=====Noncompact RAW(high align)=====
 
−
Data is saved to the high bits, and the unused low bits are filled with 0. This is one of the data formats supported by RK VICAP.
 
−
=====Noncompact RAW(low align)=====
 
−
In Noncompact RAW (low align) format, data is saved to the low bits, and the unused high bits are filled with 0. The V4L2 standard 'Y10' (10-bit Greyscale) and 'Y12' (12-bit Greyscale) formats are both stored in this way.
 
−
 
−
The pixel_layer_convert conversion tool mentioned later in the article also converts Compact RAW to this storage format for easy display using image players.
 
−
====Compact RAW====
 
−
As shown above，there is no bit padding between pixels in this storage format.
 
−
====Line stride====
 
−
To facilitate fast operations on images, the system usually provides row-aligned buffer sizes for each line of data. RK3588 uses 256-byte alignment for this purpose.
 
−
 
−
line_stride = ALIGN_UP（image_width*bits_per_pixel/8,256）
 
−
 
−
For example, when the image width is 1456:
 
−
 
−
8bit depth，line_stride=1536
 
−
 
−
10bit depth，preferred_stride=2048
 
−
 
−
12bit depth，preferred_stride=2304
 
−
====Format convert tool====
 
−
We have written a small tool: [https://github.com/veyeimaging/pixel_layer_convert pixel_layer_convert], which can easily convert Compact images to Noncompact (low align) images.
 
−
 
−
For example, the following command can convert a Compact RAW10 image with a width of 1456 to Noncompact RAW10 format:
 
−
 
−
<code>./pixel_layer_convert -I R10C -i y10-1456x1088_0001.raw -o y10-1456x1088_0001_new.raw -w 1456</code>
 
−
====Raw data image player====
 
−
We recommend using [https://www.offminor.de/ vooya] as the player, which supports GREY, and unpacked image formats.
 
−
 
−
Also, y8 file can be used with this player: [https://yuv-player-deluxe.software.informer.com/2.6/ YUV Displayer Deluxe].
 
−
===Application examples===
 
−
====Configuring  global variables====
 
−
Based on the board model, configure the I2C_BUS global variable as follows:
 
−
 
−
*Radxa Zero 3W
 
−
 
−
<code>export I2C_BUS=2</code>
 
−
 
−
For the convenience of later descriptions, global variables are configured here according to the sensor size.

<code>                   trigger_mode 0x00981901 (int)    : min=0 max=2 step=1 default=0 value=0 flags=volatile, execute-on-write</code>
 
−

−
 
−
<code>                          roi_y 0x00981906 (int)    : min=0 max=1024 step=4 default=0 value=0</code>
 
−
 
−
Parameters can be set and get using the following methods.
 
−
 
−
<code>v4l2-ctl --set-ctrl [ctrl_type]=[val]</code>
 
−
 
−
<code>v4l2-ctl --get-ctrl [ctrl_type]</code>
 
−
 
−
All the above functions can be implemented using [[Mv mipi i2c.sh user guide|mv_mipi_i2c.sh]].
 
−
 
−
Note that the above parameters cannot be modified during the capture process.
 
−
 
−
The following is an explanation of each parameter:
 
−
=====Trigger Mode=====
 
−
<code>v4l2-ctl --set-ctrl <small>trigger_mode=[0-2]</small></code>
 
−
 
−
0：Video streaming mode
 
−
 
−
1：Normal trigger mode.
 
−
 
−
2：High-speed continuous trigger mode.
 
−
=====Trigger Source=====
 
−
<code>v4l2-ctl --set-ctrl <small>trigger_src=[0-1]</small></code>
 
−
 
−
0: Software trigger mode.
 
−
 
−
1: Hardware trigger mode.
 
−
=====Software trigger command=====
 
−
<code>v4l2-ctl --set-ctrl <small>soft_trgone=1</small></code>
 
−
=====Set frame rate=====
 
−
<code>v4l2-ctl --set-ctrl frame_rate=[1-max]</code>
 
−
 
−
The maximum frame rate is automatically updated as the resolution changed.
 
−
=====Set the starting position of the ROI=====
 
−
<code>v4l2-ctl -d /dev/v4l-subdev2 --set-ctrl roi_x=0</code>
 
−
 
−
<code>v4l2-ctl -d /dev/v4l-subdev2 --set-ctrl roi_y=0</code>
 
−
 
−
After setting the ROI starting position, you need to complete the full ROI configuration using the <code>media-ctl</code> command.
 
−
 
−
Note that setting the ROI may affect the maximum frame rate, and the ROI parameters need to meet the requirements specified in the camera manual.
 
−
====Set image format using media-ctl====
 
−
use the following command to configure the camera's data format, resolution, and frame rate using <code>media-ctl</code>:
 
−
 
−
<code>media-ctl -d /dev/media0 --set-v4l2 '"m00_b_mvcam '"$I2C_BUS"'-003b":0[fmt:Y8_1X8/'"$WIDTH"'x'"$HEIGHT"'@1/'"$FPS"']'</code>
 
−
 
−
Among them: <code>"m00_b_mvcam '"$I2C_BUS"'-003b"</code> refers to the complete name of the camera entity, <code>Y8_1X8</code> is the mbus-code, <code>'"$WIDTH"'x'"$HEIGHT"'</code> indicates the resolution, <code>1/'"$FPS"'</code> indicates the resolution frame rate.
 
−
 
−
The width and height here cooperate with the roi_x and roi_y of the v4l2-ctl command to form the ROI parameter.
 
−
 
−
For example, for MV-MIPI-IMX296M, the command after variable replacement would be:
 
−
 
−
<code>media-ctl -d /dev/media0 --set-v4l2 '"m00_b_mvcam 2-003b":0[fmt:Y8_1X8/1456x1088@1/60 field:none]'</code>
 
−
 
−
You can not only configure the data format, resolution, and frame rate in one command, but also modify them separately as needed.
 
−
====Video Streaming mode====
 
−
=====Set data format, resolution, frame rate=====
 
−
<code>v4l2-ctl -d /dev/v4l-subdev2 --set-ctrl roi_x=0</code>
 
−
 
−
<code>v4l2-ctl -d /dev/v4l-subdev2 --set-ctrl roi_y=0</code>
 
  
−
<code>media-ctl -d /dev/media0 --set-v4l2 '"m00_b_mvcam '"$I2C_BUS"'-003b":0[fmt:Y8_1X8/'"$WIDTH"'x'"$HEIGHT"'@1/'"$FPS"']'</code>

1 Overview

The MV series and RAW series cameras are cameras designed for AI applications in the industrial field. They use the MIPI CSI-2 interface and are particularly suitable for use with embedded computing platforms. They have rich data formats and triggering features, extremely low latency, high bandwidth, and reliable stability.

This article takes Radxa's ZERO 3W/3E board as an example to introduce how to connect MV and RAW series cameras to the RK3566/3K3568 system.

We provide drivers for the Linux operating system (using Radxa OS Debainas an example).

2 Hardware Setup

2.1 Connection of MV series camera and Radxa ZERO 3W/3E

The MV series cameras require the ADP-MV1 adapter board in order to connect to the Radxa ZERO 3W/3E board.

The ADP-MV1 and Zero 3W/3E are connected to each other using a 15 to 22P FFC cable, taking care that the silver contacts are facing outwards.

3 Introduction to github repositories

https://github.com/veyeimaging/rk35xx_veye_bsp

https://github.com/veyeimaging/rk35xx_radxa

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 Upgrade Radxa Debain system

4.1 Overview

This section describes how to update the RK35xx system to support our camera modules.

We provide a deb installation package that can be installed directly.

4.2 Burn Radxa standard system

Refer to the Radxa documentation to burn in a standard system.

The installation package we are currently releasing is based on this image version.

4.3 Using prebuilt Image and dtb file

Using the compiled debain installation package

On the RK35xx board,

Download the latest rk356x_radxa_zero3w.tar.gz or rk356x_radxa_zero3e.tar.gz from https://github.com/veyeimaging/rk35xx_radxa/releases/ .

tar -xavf rk356x_radxa_zero3w.tar.gz

cd rk356x_radxa_zero3w/released_images/mvcam

sudo dpkg -i linux-headers-5.10.160-36-rk356x_5.10.160-36_arm64_mvcam.deb

sudo dpkg -i linux-image-5.10.160-36-rk356x_5.10.160-36_arm64_mvcam.deb

sudo reboot

If the version does not match, it needs to be compiled from the source code.

5 Check system status

5.1 Whether the camera is correctly recognized

After system update, reboot the main board.

Execute the following command on the main board to check if the camera is properly connected.

dmesg | grep mvcam

You can see the camera model and the camera version number probed.

A prompt as below indicates that the MV-MIPI-IMX296M camera is detected on the i2c-2 bus.

mvcam 2-003b: camera is：MV-MIPI-IMX296M

mvcam 2-003b: firmware version: 0x1290133

For Radxa Zero 3W/3E, the camera is connected to i2c-2.

  • Check the video0 device node:

ls /dev/video0

You should see:

video0

After successfully identifying the camera, the camera will be recognized as /dev/video0.

https://github.com/veyeimaging/rk35xx_radxa/tree/main/linux/drivers/rk356x

8 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.

https://github.com/veyeimaging/rk35xx_radxa/tree/main/i2c_cmd

using -b option to identify which bus you want to use.
