I used I.MX6DL. It has 1 IPU.
I used fb0 to camera output. and fb1 to QT's application area.
These are out put to LVDS.
And I can mirroring the fb0 or fb1 to fb2. fb2 is output to External monitor.
But I need 2 of framebuffer (fb0 and fb1 ) output to external monitor.
Is there any method to adding the 1 more framebuffer(fb3) in i.MX6DL ?
Thanks.
