# (Project -> Create Make Target...  then set the Target Name and Make Target to "program")

# OpenOCD is run in "batch" mode with a special configuration file and a script file containing
# the flash commands. When flash programming completes, OpenOCD terminates.
#
# Note that the script file of flash commands (script.ocd) is part of the project
