# "-m controller" will build only the controller's IMX
# "-m both" will build both the copter and controller IMX.  Default is both if not specified.
# "-c true" will clean the build recipies prior to beginning the build.  Default is false if not specified.
# "-n true" nuclear option will delete the entire build directory to start from a totally clean slate.  Default is false if not specified.

#TIP: how to build just one bit, such as the pixhawk firmware from OpenSolo/meta-3dr/recipes-firmware/pixhawk/pixhawk-firmware_1.3.1.bb :
#assuming you've run the 'export MACHINE...' and 'source ./setup...' commands first, and are in /solo-build/build/ folder as a result:
#bitbake -c clean pixhawk-firmware
#bitbake pixhawk-firmware
#or verbose:
#bitbake pixhawk-firmware -v
#TIP: -k means continue-after-error-for-as-much-as-possible
