[meta-freescale] Nitrogen6x2g Ubuntu kernel 3-14-52 : black screen

[Miroslav Lazic]

Hi,

I'm using Nitrogen6x 2Gb with Ubuntu image from
https://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 at 60,if=RGB666

but display remains black!
What am I doing wrong?


Console:

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