Pixhawk startup fail (video attached)

Hi guys,

Not first time I work with the Pixhaw, and so far I got them working.
But with this one, no joy. It starts boot up, but ends in a sad beep and red status LED.
APM Plane 3.2 loaded successfully from MP, current release.

So I wonder, anybody know how to make this OK?
Or is this more likely a hardware problem (then I will contact 3DR about RMA).

Start up attempt:
youtu.be/EySLN4AftrU

Coprocessor firmware update successful (or not?)
SD card deep formatted before fw update (not just quick format)
youtu.be/2I0kTGBy3hA

The simple videos are just to demonstrate clearly the Pixhaw behaviour during start up attempt and coprocessor fw update.

3DR support deemed this to be a RMA case since I tried using the forced bootloader and changing between different firmware classes (plane/multirotor and back) and the problem persisted.
And of course, since the problem was reporded within warranty time.
