因为板端内置的库较老且不适合我，所以自己更新和链接了一些库
首先更改profile——————————————————————————
/etc/profile真实路径->
/home/warren/rv1126_sdk/buildroot/board/rockchip/common/base/etc/profile
在最后添加

eth设置开发板静态ip

ifconfig eth0 10.12.13.66 netmask 255.255.255.0
route add default gw 10.12.13.1

rknn 更新rknn库

cd /usr/lib
ln -snf libOpenCL.so.1.2 libOpenCL.so.1
ln -snf libOpenVX.so.1.2 libOpenVX.so
ln -snf libOpenVX.so.1.2 libOpenVX.so.1
sysnc

opencv lib添加opencv 库

rm /lib/libopencv_img_hash.so
rm /lib/libopencv_world.so
unzip /opt/sd/lib.zip -d /tmp/
ln -s /tmp/lib/libopencv_img_hash.so /lib/libopencv_img_hash.so
ln -s /tmp/lib/libopencv_world.so /lib/libopencv_world.so
mount /tmp/lib/ /home/wzw/rk_npu_sdk/rknpu-v1.7.3/rknn/rknn_api/examples/3rdparty/opencv/opencv-3.4.3/lib/
cd /

移植opencv库——————————————————————————————————————————————-
因为rknn需要用到opencv库，故也需要移植进去
参考 https://www.ebaina.com/articles/140000016502
rknn移植opencv可以参考-> https://www.ebaina.com/articles/140000016501

更新rknn驱动——————————————————————————————————————————————
采用1.7.3版本，参考-> https://www.ebaina.com/articles/140000016476
