One of the unusual and desirable things about this is your customers for the dev board will largely be very experienced... you acknowledge it in the letter you sent out.

What surprised me is until it's fixed, there's no certainty what the problem is. Eg, dsi lanes mixed up, polarity of dsi lane wired wrong, some semidocumented reset signal on the panel got forced to 0V or forced inactive but panel requires it strobed, psu to panel must come up in specific order, psu level or quality or wiring mismatch... there are many possible ways just from having no video it can be a hw rework issue to solve it. Of course dsi is also complex, it can easy be a sw-only config issue, or some combination.

It's not up to me as your paying customer to go ask on a 'support channel' why, it's up to you to explain the reasoning why you believe that's a software-only issue.
