ti81xxfb failded to start



你好:

      TI8168evm开发板,

       dvrrdk3.0。

     移植已经可以用,视频采集也可以用,使用link-api-demo。

    在用QT进行gui时发现节点dev/db0 打开错误。

    使用fbset命令是同样错误:

    ti81xxfb ti81xxfb:failed to start

    open /dev/fb0: operation not permitted; 

     追踪了下原因,最后都指向vps_fvid2_control()函数。

   请问该问题如何解决?
