Re: QMX+ Initial Power Up Display Shows Only Boxes


 

Hi Don,
?
I don't see mention of the PCB Rev you have, but if you are slow to start building (like me) and have a Rev 1, then you might need to load the firmware.?
?
I spent three days reading these forums and testing this rail, that voltage, the other ohm's, etc. etc etc.? It was a very deep rabbit hole for sure.? Anyway I finally realized that taking my time and testing every connection while I was building led to a terrific build - no issues - except I was missing the firmware.?? Once I loaded that everything tested perfect - just as Hans said it would in the manual.? So if you are Rev 1, try to load the firmware.?
?
Rev1 - Step 2.30 - Item 3. Note that the QMX+ is normally supplied without firmware and you must install firmware first, before anything will happen (see subsequent section after finishing this “final checks” section).
?
I hope this helps you - if not maybe it will help someone else that was slow to start building their Rev 1.
?
Cheers and 72
