Dahlia is a compact carrier board providing easy access to the most common features of the Verdin family. A very convenient platform for software development and demonstration purposes, the board is compatible with all current and future Verdin SoMs.
Dahlia is a compact carrier board providing easy access to the most common features of the Verdin family. A very convenient platform for software development and demonstration purposes, the board is compatible with all current and future Verdin SoMs.
We developed the driver using the Verdin iMX8M Plus + Dahlia carrier board as an example. In addition, we have also specifically designed an [[ADP-TWG]] adapter board for signal conversion.<br />In general, you only need to use the Image file that we provided. Of course, you can also modify or recompile the driver according to our open source code.

In general, you only need to use the Image file that we provided. Of course, you can also modify or recompile the driver according to our open source code.
Now, we have added support for Verdin iMX8M Mini. Except for areas specifically mentioned, iMX8M Mini is consistent with iMX8M Plus.

Specifically, for iMX8M Mini, the driver's default configuration sets the camera's output data format to YUVY.

Toradex provides various types of images for the board. Here, we only provide the "Toradex Embedded Linux - Yocto Project Reference Images” type of image for direct burning. If you want other types of burning images, please refer to the following chapter and compile and port the driver through the source code.

As you can see, the VEYE-MIPI-IMX327S module has been successfully probed and mounted on i2c-2.

===== For iMX8M Plus =====
*Run the following command to check the presence of video node.

In fact, the camera only provides UYVY data format, and the ISI module in i.MX 8M Plus provides data format conversion function, so /dev/video3 has so many output formats.

===== For iMX8M Mini =====
*Run the following command to check the presence of video node.
<code>ls /dev/video*</code>
The output message appears as shown below.
<code>video0</code>
* List the formats supported by the camera
<code>v4l2-ctl --list-formats-ext -d /dev/video0</code>
<code>ioctl: VIDIOC_ENUM_FMT</code>
<code> Type: Video Capture</code>
<code> [0]: 'YUYV' (YUYV 4:2:2)</code>
<code> Size: Discrete 1920x1080</code>
Due to the absence of the ISI module in i.MX 8M Mini, /dev/video0 can only directly output the data format from the camera.
