# DESCRIPTION:  A script that contains a bunch of app and bsp switches that will generate the makefiles, compile the code, download the code, open a terminal.
#               Pass in a cable number if you have multiple programming cables.
# Usage:        ./batch_script <optional cable number>
#               ex:  ./batch_script 2
#               If you are not sure of your cable number type 'jtagconfig' to list all the cables connected to the host (or remote cables)
