SemiDrive D9360 AHD Camera 1080P 調試

關鍵字 :SemiDriveD9360AHD
SemiDrive D9360 EVK 目前支持2路MIPI-CSI  1路parallel-CSI 接口，total 9個camera ,本次調試和測試MIPI-CSI2接N4 再連結1080P AHD camera.

1. 查看SCH AHD camera 的連結狀況。

 N4 AHD Camera input


N4 AHD Camera output



D9360 AHD Camera input

N4 I2C bus & slave address



2. 根據硬體原理圖配置好 dts 文件。

修改相應1080P部分
