2 How to test NPU

2.1 OS

Tested on the following OS:

2.1.1 Debian11 (bullseye)

• rk3588-sd-debian-bullseye-desktop-6.1-arm64-20240116.img.gz
• rk3568-sd-debian-bullseye-desktop-6.1-arm64-20231113.img.gz

2.1.2 Ubuntu20 (focal)

• rk3588-sd-ubuntu-focal-desktop-6.1-arm64-20240116.img.gz

2.2 install rknpu

export GIT_SSL_NO_VERIFY=1
git clone https://github.com/rockchip-linux/rknpu2.git
cd rknpu2
git checkout tags/v1.5.2 -b v1.5.2
sudo cp ./runtime/RK3588/Linux/librknn_api/aarch64/* /usr/lib
sudo cp ./runtime/RK3588/Linux/rknn_server/aarch64/usr/bin/* /usr/bin/

2.3 check rknn version

strings /usr/bin/rknn_server |grep 'build@'
strings /usr/lib/librknnrt.so |grep 'librknnrt version:'

2.4 run rknn_yolov5_demo

sudo apt-get update
sudo apt-get install -y gcc g++ make cmake
cd examples/rknn_yolov5_demo
./build-linux_RK3588.sh
 
cd install/rknn_yolov5_demo_Linux
./rknn_yolov5_demo model/RK3588/yolov5s-640-640.rknn model/bus.jpg

Transfer the generated out.jpg to PC to view the result:

scp out.jpg xxx@YourIP:/tmp/
