During test, I have found that some boards are unable to drive the connected LCD display panel. Further investigation leads me to believe that it is the missing level shifters on the Minnowboard Max which mean that this is not working as expected (connecting other HDMI sources to the board, i.e. PC, etc. work absolutely fine. Inspection of the diff pair levels on a scope shows that it is definitely marginal). <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I understand that revision A4 of the board (<a href="https://bugzilla.yoctoproject.org/show_bug.cgi?id=7027">https://bugzilla.yoctoproject.org/show_bug.cgi?id=7027</a>) will include these level shifters. My question is whether this revision of the board is available yet, and if so, how I couple go about ordering a couple of them for test to ensure it solves my problem. I purchase around 10 boards around a month or so ago, and these are all revision A2.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any insights or additional information would be most helpful.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Leigh<o:p></o:p></p></div></body></html>
