Hi,igorpadykov:
thanks for u help.
thanks!!!
But,
Because L3.10.53 BSP (yocto project) is only open fb0 to use, so I can not throw display information to show another fb for dual display.
The L3.10.53 BSP dual display is not the beginning of the same show screen.
Another screen,I must throw things to display,because Framebuffer data is 0.
So,
How to Write freescale imx6q control fb (framebuffer) control program?
Or how to control fb?
My experience is not enough, do not know how to write this control program, please help me.
please help me,thanks.

謝謝你的幫忙。
但是,因為 L3.10.53 BSP(yocto project)只打開fb0去使用,所以我不能丟顯示資訊到另一個fb在雙顯示下。
L3.10.53 BSP 雙顯不是一開始就秀相同的畫面。
另外一個畫面,我必須丟東西去顯示才行,因為Framebuffer 資料是0 。
所以,如何去寫一個freescale imx6q 的控制程式呢?
或者如何去控制fb?
我經驗不夠,不知道如何撰寫此控制程式,請幫忙我一下。
請幫助我,感謝。
