@george 是插到上面的usb3.0端口，不知道是不是boot也必须升级，我之前是重新刷过boot

离线烧写android镜像

1. 离线只做U盘启动盘（提示制作已经成功）
2. 将U盘启动盘插入usb3.0接口
3. 重启开发板

期望是进入android镜像，实际上还是启动的旧的ubuntu镜像

UVC相机接入gstreamer mpp初始化失败。

运行如下命令
#gst-launch-1.0 v4l2src device=/dev/video20 ! image/jpeg, width=1280,height=720,framerate=120/1 ! jpegparse ! mppjpegdec ! videoconvert ! xvimagesink

报错如下：

使用jpegdec没有问题

多谢
编译OpenCV的时候，应该可以打开OpenCL使用mali的GPU吧

RK3588是否支持opencv算子的NPU加速
