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' Change-Id: I61233bca9605ba89c3628c2a65ca9013c56365ea Reviewed-on: https://chromium-review.googlesource.com/359355 Commit-Ready: Chris Chen <twothreecc@google.com> Tested-by: Chris Chen <twothreecc@google.com> Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org>
