大家好,
我基于DM8148 IPNC RDK3.8开发,想同时运行link和QT程序,现在各自都是能运行,但是同时运行报错:
[m3vpss ] 89180: Assertion @ Line: 1089 in links_m3vpss/display/displayLink_drv.c: pObj->displayHndl != NULL : failed !!!
和下面帖子的遇到的问题一样,但是没看到最后是怎么解决的。

我配置QT是参照这个帖子: http://www.deyisupport.com/question_answer/dsp_arm/davinci_digital_media_processors/f/39/t/45366.aspx
link_display 默认是使用/dev/fb0的
启动qt应用程序的时候添加 -display linuxFb:/dev/fb1
然后需要显示qt程序时,使用 echo 1 > /sys/.../graphic1/enabled启用就可以了
