Thanks! I tried adding -platform eglfs but the result is still the same. Either mouse and keyboard doesn't response.
I believe the default platform is eglfs. So, even I don't use -platform option, the it should run with eglfs platform. Am I right? My reference is here http://doc.qt.io/qt-5/embedded-linux.html. Any more suggestion?
