Hi eveyone,

I'm working to start linux on my IMX6 SABRE_SD board,and my LVDS is connected to LVDS1.After I

configured U-boot and boot,only 4 penguins are displayed on my LVDS.

My U-boot config is:

printenv:

bootargs_nfs=setenv bootargs $ root=/dev/nfs ip=dhcp nfsroot=${serveri

p}:$,v3,tcp video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666 ldb=sin1

And my linux boot process is:

Did you flash a GUI image? try running a gstreamer pipe to check the video output (gst-launch videotestsrc ! mfw_v4lsink).

No, if I use ltib to buid my own file system((use packages in preconfig (Min profile)), the LVDS display only four penguins, but if I use  rootfs.ext2.gz in the package, the LVDS work well and displays some folders like 'Avtive Tasks','Office','Internet','Sound $ Video' and so on. I can do some operation by touching the panel.

Is there some guide for building rootfs?
