I successfully built kernel, u-boot, boot.img, ramdisk, etc. for sabresd platform following Android User's Guide.
Now I would like to build for sabrelite platform but I don't know which lunch target to use to build for it.
Could someone give a hint on this?
follow the directions here on the boundarydevices web site for building android. You have to pull down the sources from boundarydevices' github repos:

Freescale does not support that board. Check BD page for Android Systems.
