   7 # Note, the compulab package contains a binary NAND driver that is not
   8 # EABI compatible
   9 # if you get a md5 sum error on x270-linux-drv.zip, compulab has probably
  10 # changed the binary.  Remove it and the md5 file from your tmp directory,
  11 # and rebuild the kernel.  If you still get md5 failures, contact cbrake
  12 # on the #oe IRC channel -- this recipe probably needs updated.
