RK3566-buildroot SDK-Graphics问题咨询
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
Target packages-->Rockchip BSP packages-->rockchip libmali-->OpenGL EGL
Target packages-->Rockchip BSP packages-->rockchip libmali-->OpenGL ES
Target packages-->Rockchip BSP packages-->rockchip libmali-->OpenCL
Target packages-->Rockchip BSP packages-->Minigui use software scale
Target packages-->Compressors and decompressors-->gzip
Target packages-->Graphic libraries and applications-->weston
Target packages-->Graphic libraries and applications-->xkeyboard-config
Target packages-->Graphic libraries and applications-->QT5-->eglfs support
Target packages-->Graphic libraries and applications-->QT5
-->Pixel format of linuxfb drm screen
Target packages-->Graphic libraries and applications-->QT5-->qt5wayland
Target packages-->Libraries-->Graphics-->wayland
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！
