Hi

Check your directory, default is in build/linux, and see if you see 
your build objects there.  For things to be populated onto the
default RAM rootdisk they should be in the build/linux/install
directory.  If you specify linux_apps=... it should do this for you.

What release are you using and what command line did you use to invoke
the build system?
