Hi Tarek,
Are you using multiple displays?
If not, you're going to want these
video=mxcfb1:off video=mxcfb2:off video=mxcfb2:off
Otherwise you'll get a default LDB display. You can check this
in /sys/class/graphics/fb2/.
Did you try running the DVI monitor with "mxc_hdmi.only_cea=0" in your
kernel command-line?
I'm not sure what dmfc=3 is doing to the display, but I suspect
that you're exceeding the bandwidth requirements with multiple
displays configured.
I'm also not certain what you're running into with the
gstreamer build.
Regards,
Eric

Hi Eric,
On the command line arguments I had dmfc=3. That was set to improve the
IPU performance as I need to play up to 16 streams simultaneously.
When I removed this option the boundary kernel is booting without the
horizontal lines problem. HDMI to DVI is still not working.
cat /proc/cmdline
console=ttymxc1,115200 video=mxcfb0:dev=hdmi,1920x1080@60 fbmem=24M,10M
root=/dev/mmcblk0p1 rootfs=ext2 rw rootwait enable_wait_mode=off
consoleblank=0 bpp=32
This is fine for know but it would be nice to understand why dmfc is
conflict with boundary kernel.
Also I'm not sure how is this going to affect the IPU performance!
Hope you have an answer to this question so I can fully test the
application.

The command line argument doesn't help:
console=ttymxc1,115200 video=mxcfb0:dev=hdmi,1920x1080@60 fbmem=24M,10M
root=/dev/mmcblk0p1 rootfs=ext2 rw rootwait enable_wait_mode=off
consoleblank=0 dmfc=3 bpp=32
Also

This looks like a pretty standard set of modes for a
4:3 aspect ratio monitor.
root@nitrogen6x:~# cat /sys/class/graphics/fb0/mode
S:1280x1024p-60
This doesn't match one of the CEA modes:
https://github.com/__boundarydevices/linux-imx6/__blob/boundary-imx_3.0.35_4.1.__0/drivers/video/mxc/mxc_edid.__c#L41
<https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_3.0.35_4.1.0/drivers/video/mxc/mxc_edid.c#L41>
Can you boot with this command-line argument?
mxc_hdmi.only_cea=0
I think you'll either need that or you'll need to choose a
display resolution from the list. It appears that your monitor
and CEA both like 1280x720@60, though you'll likely get
letter-boxing.

Eric
