器件型号：SK-AM62A-LP工具/软件：
尊敬的 TI 专家：
我正在尝试将 Pcam5c（具有内置 ISP 的 ov5640）连接到 SK-AM62A-LP。
PSDK 的版本为 11.01.07.05。
我按如下方式修改了器件树、

对设备树的修改似乎正常工作。

当我登录时、将显示消息。

接下来、我尝试使用以下命令进行摄像头流式传输。
gst-launch-1.0 -v v4l2src device=/dev/video-ov5640-cam0 io-mode=5 ! \ video/x-raw, width=1280, height=720, framerate=30/1,format=YUY2 ! \ kmssink driver-name=tidss sync=false
结果如下、HDMI 显示屏上不显示任何图像。

如果您有解决方案、如果您能告诉我、我将不胜感激。
