function usage() {
    cat << USAGE
Usage: ./test/fpga_manual_test.sh -u <UART PORT ATTACHED> -n -p.
-n Controls whether a new fpga bitfile is built
-p Controls whether the existing bitfile at build/lowrisc_systems_top_earlgrey_nexysvideo_0.1
is programmed.

The following command builds the fpga, programs it onto the device and begins testing
./test/fpga_manual_test.sh -u /dev/ttyUSB0 -n -p

The following command assumes there exists a bitfile already, programs it and begins testing
./test/fpga_manual_test.sh -u /dev/ttyUSB0 -p

The following command assumes the bitfile is already programmed and begins testing
./test/fpga_manual_test.sh -u /dev/ttyUSB0
