You point out something that we do not as of yet have a full testing suite and bandwidth in the team to do the sort of testing you are discussing. I myself don’t often use boards back to 5.0 but I can say that we feel the firmware may be involved here. As of the shipments of Raspberry Pi 4 in units we have had to fix many issues to maintain proper operation with raspberry pi 4 boards.
I confess we lack manpower to do regression testing on these images back farther than MCB rev 5.2 (the first board to support Raspberry Pi 4 more excessive power requirements.
What I think we COULD do to better inform customers of our images is clearly state in the image info what versions of raspberry pi and MCB rev and MCB firmware we did test this image upon.
These days that would be a current MCB rev 5.3 with mods to support a Raspberry Pi 4 that wants 5.1V.
Rev 5.0 MCB boards are (sadly) seldom to never tested with these images. That is the reality of our small testing capacity as well as what units we have that even have rev 5.0 boards. We consider rev 5.1 boards using Raspberry Pi 3 or 3B processors as still something we wish to support well. It is frankly a function of our ability to cross test these combinations. I am sorry it seems to have been an issue for your Magni.
This is ‘non ideal’ but we are still a small-ish company and must prioritize testing efforts.
Thank you for your feedback it will be discussed so we can either inform users of what configurations are tested for a given version and perhaps expand our image qualification tests.
