cts: Added sync() function
sync() involves 2 gpios on each board, each labeled
GPIO_HANDSHAKE_OUTPUT and GPIO_HANDSHAKE_INPUT on
their respective boards. They both start low,
then the th wiggles his line up and down, waiting
for the dut to mimic it.
BRANCH=None
BUG=None
TEST=manual
- Connect handshake lines to appropriate
pins on each board (pins found
in board's gpio.inc)
- Build tests
- Flash boards
- run 'cat /dev/ttyACM0' in one terminal
- run 'cat /dev/ttyACM1' in another
- They should each have printed
'successful sync'
