    • 回复: V853可以使用usb摄像头吗？

      @whycanservice 灰常感谢！！！😀
      最后尝试了一下成功了
      make menuconfig下修改的选项和make kernel_menuconfig有点冲突
      make menuconfig不需要做修改，只需要添加内核支持就可以了

      cat /sys/devices/platform/soc/usbc0/usb_host
      插上摄像头识别出来了

    • V853 编译MPP sample ，开发板运行报错

      使用大佬给的mpp 编译示例代码
      https://gitee.com/GloomyGhost/Yuzukilizard/tree/master/Software/sunxi-mpp
      开发板烧录出厂固件，运行自己编译的sample_virvi2vo出现报错：
      ISP_ERR]isp_sync_debug_info, line: 747,VIDIOC_VIN_ISP_GET_INFO error!

      运行结果：

      这个报错，我在运行自己其他的示例程序也会出现，但是它好像不影响运行的结果，但是这也是不正常的吧，我尝试修改了一部分代码，但是我不知道是什么地方导致了这个错误的发生，萌新求助，感谢大佬！

      @whycanservice 灰常感谢！！！😀
      最后尝试了一下成功了
      make menuconfig下修改的选项和make kernel_menuconfig有点冲突
      make menuconfig不需要做修改，只需要添加内核支持就可以了
      ---->make kernel_menuconfig
      ---->Device Drivers
      ---->Multimedia support
      ---->Media USB Adapters

      插上摄像头识别出来了

    • V853可以使用usb摄像头吗？

      首先尝试了用cat /sys/devices/platform/soc/usbc0/usb_host后
      插上USB摄像头

      摄像头没有识别出来

      然后又尝试了make menuconfig后，修改了
      ----OpenWrt Configuration
      ---- Kernel modules
      ----Video Support

      make -j1 V=s 后报错如下
