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.
