海思3536C移植Qt5.12,不显示界面
大家好, 最近移植Qt5.12到海思的3516C平台上,编译和运行测试代码都没有报错(中间有一些报错已经解决了),但是显示不出来窗体界面,不知道什么原因; 使用海思sdk里的sample_hifb例子,例子运行正常,可以显示,但是启动qt程序后,示例代码的界面会被刷掉,但是屏幕上什么也不显示。 显示是基于linuxfb插件,修改插件里的代码加一些打印信息:
xres= 1280 yres = 720 xres_virtual = 1280 yres_virtual = 720 xoffset = 0 yoffset = 0 bits_per_pixel = 16 grayscale = 0 height = 0 width = 0 finfo.line_length: 2560 ******************* [ui]: depth: 16
[ui]: in determineFormat, depth: 15 QLinuxFbScreen::initialize() mBytesPerLine: 2560 mMmap.size: 16588800 mGeometry: QRect(0,0 1280x720) mPhysicalSize: QSizeF(325, 183)
不知道和Format有没有关系; 通过查看linuxfb的代码,看到里面并没有修改fb的参数,只要sample_hifb里有修改,sample_hifb启动后,打开了Vo设备,初始化好fb,然后启动qt,就是看不到界面…… 大家有没有遇到过这个问题的,帮提一个排除问题的思路,谢谢!
