Luckfox Pico Ultra W RKNN Installation Problem

[Doruk-Dilmen]

Hi,

I am using Luckfox Pico Ultra W board to develop yolov5 custom model. I installed RKNN-Toolkit2 on my PC. I did eveything according to the RKNN on PC side but. I loaded the image on my board using this link https://wiki.luckfox.com/Luckfox-Pico/Luckfox-Pico-RV1106/Luckfox-Pico-Ultra-W/Luckfox-Pico-emmc-burn-image. I copied the project file to my board. Then I use this command:
cd /root/rknn_yolov5_demo/
./rknn_yolov5_demo model/yolov5.rknn model/bus.jpg
I get this response
-bash: ./rknn_yolov5_demo: No such file or directory

Can you help me? Should I try to install rknn to my board from this link https://github.com/rockchip-linux/rknn-toolkit/tree/master/rknn-toolkit-lite/packages ?
