lcd和hdmi显示yuv格式的数据的问题

大家好    板子型号是imx6q    核是4.1.15   

bootargs  :  setenv displayinfo 'video=mxcfb0:dev=lcd,MDP02BP,if=VYUY16

video=mxcfb1:dev=hdmi,1920x1080M@60,if=VYUY16'
或者

setenv displayinfo 'video=mxcfb0:dev=lcd,MDP02BP,if=VYUY16

video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24'



lcd输出为yuv422的数据    

我们理解的是hdmi的数据不会受到lcd的数据格式的影响,所以开始想hdmi的数据为rgb的就可以,但是lcd上的图像是正常的,但是hdmi的图像不正常   图像是绿色的

请问是什么情况呢   需要对hdmi的驱动进行修改吗?

谢谢

if HDMI+LCD,you can refer to the command as below I have tested successfully:
video=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB24 bpp=32
video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24 bpp=32
