From: Gwenhael Goavec-Merou <gwenhael.goavec-me...@trabucayre.com> With trigger enabled, and with pulseview, a second (or more) acquisition start immediatly instead of blocking. It's mandatory to try several times to have a correct behavior.
According to http://mygizmos.org/ols/Logic-Sniffer-FPGA-Spec.pdf section 2.3.1 p.8, the openbench logic sniffer must be reset before each arm command.
