Hi,

I have the same problem on my Linux 3.0.35 iMX6q. I use Buildroot 2014.02. In older buildroots I haven't got this warning. Until I merged to a newer version.

Is there now a solution for this??

Thanks

Andi

I'm having similar issue with my Sabre board from Boundary Devices.  I'm using the Linaro Ubuntu Desktop version 12.05

I flash my board according to :

http://boundarydevices.com/running-linaro-ubuntu-on-i-mx6-sabre-lite-and-nitrogen6x/

how ever when I start it up then my display(HP ZR22w) is not being detected.  I have tracked this down to something to do with the boot.scr in the boot partition.  Basically if I change then line:

setenv bootargs "console=tty0 console=ttymxc1,115200n8 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 root=UUID=93047a55-33e3-4455-97fb-d7c399261e6c rootwait ro"

to

setenv bootargs "console=ttymxc1,115200n8 video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24 vmalloc=400M fbmem=28M no_console_suspend root=UUID=93047a55-33e3-4455-97fb-d7c399261e6c rootwait ro"

then recreate the bootscripts with the online tool :

http://git.boundarydevices.com/bootscript.php

and replace the boot.ini boot.scr and boot.txt

Then my display detects and can show the Ubuntu loggin, how ever it goes to sleep after ~20 sec flashing:

"Input Signal Out of Range Change Settings to 1920 x 1080 - 60Hz"

I can see the line:

[   15.150540] imx-ipuv3 imx-ipuv3.0: WARNING: adapt panel end blank lines

being printed out in the serial console....

Can anyone see what I'm doing wrong?
