    I am getting "No signal" on the web interface.

    dmesg shows repeated message:

    unicam fe801000.csi: Device has requested 3 data lanes, which is >2 configured in DT

    Any idea what is wrong?

        Info:

        TinyPilot Pro version 2.6.4

        Tried two different types of VGA to HDMI converters (including the FOINNEX one).

        Only worked intermittently a while back, and then I messed up somewhere, and had to re-image the micro SD.

        Don't think the HDMI capture has worked since then.

            Since the error message is referring to the device tree, maybe I imaged the micro SD card incorrectly?

              Hi @ErnestHua, I'm sorry you're running into this No Signal issue.

              If you're using a VGA to HDMI adapter, I suspect the adapter is outputting a display signal that TinyPilot doesn't support (likely 1920x1080 at 60Hz). The workaround here is typically to manually adjust your target machine's display output settings to one of the supoprted settings in this list.

              To confirm this is the issue, could you share a TinyPilot log? On your TinyPilot web interface, go to System > Logs and click Get Shareable URL. Then paste the link in your reply.

              I hope that helps! Please let me know if you have any questions.
