Nitrogen6x2g Ubuntu kernel 3-14-52 : black screen

Hi,I'm using Nitrogen6x 2Gb with Ubuntu image fromhttps://boundarydevices.com/mx-linux-kernel-3-14-52 and U-Boot 2015.07-15001-g440d481 (Oct 07 2015 - 12:32:09 -0700).Also, I set 
allow_noncea=1
bootargs=video=mxcfb0:dev=ldb,1024x600M@60,if=RGB666

but display remains black!

What am I doing wrong?

Console:

non-CEA modes allowed on HDMI, audio may be affected

Hi,

As the blog post says:

This release uses the same mechanism as the 3.14.28 which means that U-Boot is in charge of setting the display parameters in the device tree. So it requires to use U-Boot v2015.07 or higher. Please make sure to read our blog post about this release:

• https://boundarydevices.com/compiling-latest-u-boot-for-i-mx6-2015-edition/​

What LVDS display are you using? Once you know its name, please find its match using:

=> fbpanel lvds

Once found, you can setup the display settings accordingly (here is an example for the hannstar LVDS display):

=> setenv fb_lvds hannstar

=> setenv fb_lcd off

=> setenv fb_hdmi off

=> savee && reset

Hope this helps.

Regards,

Gary
