Openembedded for the OpenPLi 4 environment has been initialized
properly. Now you can start building your image, by doing either:
MACHINE=... make image
or:
cd /home/xxx/openblackhole/openblackhole-oe-core/build
source env.source
MACHINE=... bitbake openblackhole-image
or, if you want to build not just the image, but the optional packages in the feed as well:
MACHINE=... bitbake openblackhole-feed
