I thought this timing generator can detect the sync timing automatically. Also I saw some mail discussions where this timing generator can trigger missbehaviours. Since we send the sync packages from the dsi-host to the ADV, I think it should be possible for the ADV to reconstruct the sync signals without the need of the internal timing generator. > Are you thinking the imx8mm DSI generator would do it better? You mean the porches we are sending? Regards, Marco
