Our customer board(i.MX6Q SDB) have dual channel 1080pLVDS panel + HDMI  port, but same time we could use one port  in linux system only.

 

linux+ ubuntu

uboot para:

1.

setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootwait rw video=mxcfb0:dev=ldb,LDB-1080P60,if=RGB24,bpp=32 ldb=spl0 video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb2:off'

We could get lvds output, but hdmi does't output.

2.

setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootwait rw video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:dev=ldb,LDB-1080P60,if=RGB24,bpp=32 ldb=spl0 video=mxcfb2:off

We could get hdmi output, lvds does't output.

3.

android JB

we could get two port output at same time.

 

So, how can i get lvds and hdmi output sametime when i use ubuntu OS?
