SABRE Platform's screen always blank in L3.0.35_1.1.0_image.

Hello,

I have download L3.0.35_1.1.0_121218_images_MX6.tar.gz then running it on SABRE Platform through NFS.

But the screen of the devkit always blank.

I have tried those boot args.

### For LVDS0 connection

setenv bootargs_nfs 'setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666'

### For LVDS1 connection

setenv bootargs_nfs 'setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666 ldb=sin1'

### HDMI

setenv bootargs_nfs 'setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'

with the last one I can saw the desktop on TV, but none of those bootargs can light up devkit's screen. 

How to light up the devkit screen in L3.0.35_1.1.0_image? , the screen works under android.

thanks.

Hello Mao,

     I seem to be having the same issue. Everything boots up fine but I see nothing on the display when I run the openGLES2 sample applications. Can you please share what was done to fix this issue?

Thanks

Hello Mao,

Are you able to paste the log of the device when booting?. I want to know if there is an error shown on hyperterminal.

So, the LVDS screen works when you are using Android but not Linux, correct?
