器件型号：AM3352 您好！
我们正在基于 AM3352的电路板上运行 Qt 应用。
当我们尝试执行任何 Qt 应用程序时、会出现以下错误：
root@am335x-evm:~# cd /usr/share/qt5/examples/gui/analogclock/ root@am335x-evm:/usr/share/qt5/examples/gui/analogclock# ./analogclock Failed to create wl_display (No such file or directory) qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland. Aborted (core dumped)
我们还观察到 Weston 未运行。
