Can anyone suggest why my BBMASK is not working? Maybe I'm not putting it into the right file? Did I construct the regex incorrectly? In my conf/bblayers.conf I have, BBMASK .= "qemu" Then I wipe out the cache by deleting the "tmp/" directory. Now I would expect bitbake -n -c fetch qemu to give a 'Nothing PROVIDES' error. That is not what happens. Instead it still completes normally. I am trying to ignore recipes like meta-freescale/recipes-devtools/qemu/qemu_qoriq.bb Thanks in advance for any help. - Chris
