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