VEYE CS Camera on Forlinx i.MX8 board
1 Overview
OKMX8MPQ-C board from Forlink embedded uses i.MX8M plus processor.
On the basis of Forlink 's official SDK(OKMX8MP-C_Linux5.4.70+Qt5.15.0 version), our camera module driver is added, and some application layer routines are provided.
In general, you only need to use the Image and dtb that we have compiled. Of course, you can also modify or recompile the driver according to our open source code.
1.1 Camera module list
| Series | Model | Status | Adaptor board |
|---|---|---|---|
| VEYE series | VEYE-MIPI-IMX327S | Done | ADP-Forlinx |
| VEYE series | VEYE-MIPI-IMX385 | Done | ADP-Forlinx |
| VEYE series | VEYE-MIPI-IMX462 | Done | ADP-Forlinx |
VEYE and CS series camera modules are camera module with ISP functions build in. It output UYVY/YUYV data using MIPI-CSI2. We provide V4L2 interface for video streaming apps , and Video Control Toolkits (which is Shell Script) to control the camera module directly, which is called DRA(Directly Register Access).
Specifically, on this i.MX platform, the default driver configures the camera to YUYV format.
2 Hardware Setup
We use ADP-Forlinx to connnect the camera with OKMX8MPQ-C board.
The camera and ADP-Forlinx are connected using 1.0 mm pitch*15P FFC cable with opposite direction. The cable must be inserted with the silver contacts facing outside.
3 Upgrade OKMX8MPQ-C system
3.1 Overview
This section describes how to update the MYD-JX8MX system to support our camera module. To support our camera module, we need to update two parts of the system, Image and DTB.
In the Image, we added the camera driver, while the DTB indicates the camera model used. In general, you only need to use the Image and DTB, that we have prebuilt, and you don't need to build from source when it is not necessary.
The released files were compiled based on the image of OKMX8MP-C_Linux5.4.70+Qt5.15.0 version.
