I'm using the iMX6DL and linux 3.0.35 kernel.
One display connected to the LVDS output of the iMX6DL and the VGA Moniotr is using the external analog devices ADV7125 DAC.
As I reviewed so many threads in this community which concerned about mirroring.
At this time, I could see the each output but I couldn't see the mirroring output. (same time, same screeen)
If I want to mirroring of LVDS and LCD, then it need 2 IPU?
Because iMX6DL has only 1 of IPU,
so I set the same IPU id to LVDS and LCD.
And I set the different channel of disp_id.
But it doesn't working.
here is my uboot code
"root=/dev/mmcblk0p1 rootfstype=ext4 rootwait rw video=mxcfb0:dev=ldb,LDB-VGA, ldb=sin0 bpp=32 video=mxcfb2:dev=lcd, LCD-640480, bpp=32, if=RGB24\0"
I set the mxcfb0 to ldb, and mxcfb2 to LCD.
this is LDB's timing
"LDB-VGA", 60, 640, 480, 15385,
And LCD's timing is
"LCD-640480", 60, 640, 480, 39683, 45, 114, 33, 11, 1, 1,
when I check the fbset in terminal,
fb0 and fb2 is same as LDB-VGA's timing.
It seems like my uboot code is not working. (mxcfb2's setting.)
Because if I change the mxcfb0 to lcd and mxcfb2 to lvds,
then lcd is working but lvds is not working.
What can I do?
Is this need to 2 of IPU?
