#   These are also the defaults that will be used if options are not specified

# EXAMPLE: builder.sh -a Pedals2Paddles -r 3dr-arm-yocto-bsp -b v0.1.0
#   This will use Matt's fork with a branch named v0.1.0

#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-alt/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

# these clean command/s are very verbose, and return an error code even though the clean works, lets quieten them:
