	mbed new --program RCNoster --scm git --offline -v

set the default board

	mbed target NUCLEO_F411RE

export to create makefile

	mbed export --profile debug -i GCC_ARM -v

	mbed export --profile debug


For openOCD use these paths

/usr/share/openocd/scripts/board/st_nucleo_f4.cfg

/usr/share/openocd/scripts/interface/stlink-v2-1.cfg or stlink-v2.cfg
