树莓派4B连接csi摄像头,然后dev里已经显示video0,用vcgencmd get_camera命令,得到supported=1 detected=1,系统已经检测,但是用raspistill -o Desktop/image.jpg命令时,还是无法打开摄像头模块,mmal: mmal_vc_component_enable: failed to enable component: ENOSPC mmal: camera component couldn't be enabled mmal: main: Failed to create camera component mmal: Failed to run camera app. Please check for firmware updates,得到这些,请大佬帮帮我,解决一下问题,谢谢!
