你好，现在我们想基于你们ROC-RK3566-PC开发板使用QT+elgfs框架开发图形界面；
在buildroot的make menuconfig的配置：
Target packages–>Rockchip BSP packages–>rockchip libmali–>display platform[set GBM]
Target packages–>Rockchip BSP packages–>rockchip libmali–>OpenGL EGL[set yes]
Target packages–>Rockchip BSP packages–>rockchip libmali–>OpenGL ES[set yes]
Target packages–>Rockchip BSP packages–>rockchip libmali–>OpenCL[set yes]
Target packages–>Rockchip BSP packages–>Minigui use software scale[set no]
Target packages–>Compressors and decompressors–>gzip[set yes]
Target packages–>Graphic libraries and applications–>weston[set no]
Target packages–>Graphic libraries and applications–>xkeyboard-config[set no]
Target packages–>Graphic libraries and applications–>QT5–>eglfs support[set yes]
Target packages–>Graphic libraries and applications–>QT5
–>Pixel format of linuxfb drm screen[argb8888]
Target packages–>Graphic libraries and applications–>QT5–>qt5wayland[set no]
Target packages–>Libraries–>Graphics–>wayland[set no]
现在update开发板的固件运行后发现，在串口连接板子的情况下，开机首次运行qplayer或其他qt应用是可以运行的，但是运行完毕再次运行后就提示什么gbm busy；而在ssh连接板子的情况下，即使第一次开机运行qt应用程序，会直接提示找不到EGL display！
麻烦帮忙看下啊！
