I'm wondering if there's something faulty with the i2c lines > on one of the chamelium boards in CI? There are a couple of I2C related > sightings open right now. I believe this isn't an I2C issue. The receiver on the Chamelium has an I2C register that indicates whether there's a stable video signal received from the DUT. The Chamelium device will wait for this register to indicate that video is stable. That is, it will poll the register each second and check whether video is stable. If after 10 seconds the register still indicates video isn't stable, the Chamelium server will give up and report this error. So this isn't an I2C timeout, it's just the Chamelium device not receiving stable video even after waiting for 10 seconds. This error usually means that no data is received.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
