推送执行文件到板子

连接板子的usb口到PC,将整个demo目录到 /data:

adb root
adb remount
adb push Z:\rockchip\rk3576-linux\external\rknpu2\examples\rknn_yolov5_demo\install /data/

运行

adb shell
cd /data/install/rknn_yolov5_demo_Android 
export LD_LIBRARY_PATH=./lib
chmod 777 ./ -R
./rknn_yolov5_demo model/RK3576/yolov5s-640-640.rknn model/bus.jpg

运行完成会在当前路径下输出结果图像out.jpg
