虚拟机ubuntu22.04, 开发板pico pro max, 花屏-清屏功能正常但输入命令时会报没有储存空间；
在虚拟机按照例程luckfox_yolov5的说明进行编译后cpp/luckfox_yolov5_demo路径下没有名为luckfox_yolov5_demo_test的文件，只有rknn_yolov5_demo_test及lib和model文件夹。拷贝至板端后用rknn_yolov5_demo_test替换命令中的luckfox_yolov5_demo_test，可以正常配置权限，但在输入./rknn_yolov5_demo_test ./model/yolov5.rknn运行时会报错:
-bash: ./luckfox_yolov5_demo_test: No such file or directory
尝试在虚拟机下运行时报错:
arm-binfmt-P: Could not open '/lib/ld-uClibc.so.0': No such file or directory
您好，花屏和清屏运行时输入命令报cat: write error: No space left on device 是正常现象，cat /dev/zero > /dev/fb0 no left 就是把清零数据不断写入/dev/fb0 直到设备的空间被占满报错No space left on device ，主要用来测试屏幕是否正常工作。
make install 编译后没有生成 luckfox_yolov5_demo_test 是我在进行整理工作时的疏忽，正确的可执行文件应该是rknn_yolov5_demo_test
这个例程是基于buildroot镜像开发的，其他镜像（如 ubuntu）缺少相关的摄像头驱动和动态链接库无法运行，报错-bash: ./luckfox_yolov5_demo_test: No such file or directory 的原因可能是您使用的是ubuntu系统。
在虚拟机上报错是因为该程序是运行在arm平台上（基于uclibc）的，虚拟机的架构与arm不同是无法正确运行的。
我换到了buildroot镜像，运行时出现以下信息并卡住，没有响应:
# ./luckfox_yolov5_demo_test ./model/yolov5.rknn
