Since your MACHINE is presented as "k2", the .conf file has been
picked up correctly. So far so good.
You should not need to add anything else in your bblayers.conf.
The new errors you are referring to might have nothing to do with your
current MACHINE setting.
You need to show the actual error you get. Not much we can do to help otherwise.

Thanks.
