    • RE: CM5 sctp运行报错

      @asdf SCTP的协议是需要内核支持的,你要再内核源码中开启相关配置,重新编译替换内核,然后在文件系统安装对应的包才可以正常使用。

    • RE: Strange screen-freezing issue

      @murraytodd I just tested the image of 22.04 and 23.04, and there was no phenomenon you described. Whether creating a new user with a shell or using the image interface, it was normal. After logging in, the new user can operate the system normally, including restarting, logging out, and other operations.

    • RE: ubuntu 0306 有时桌面卡死

      @Twsuts

      • 目前跟踪到的问题是,视频窗口全屏状态下,gnome会发afbc的图层格式给VOP,但这种格式是VOP Esmart图层不支持的类型,内核监测到这种异常图层就会报不支持的log,屏蔽掉出错log浏览器视频播放不会有影响。

      • 然后测试了QV4L2打开摄像头然后全屏,没有发现黑屏的现象,可以参考一下QV4L2的全屏操作方式。

    • RE: CM5底板原理图问题

      @qys2022 不要直接用5V给核心板供电,最简单的方法是串一个二极管。最好的方法是单独4V供电。SCT2450可以使用。
