its a VM-009 but not a Phytec baseboard and luckily I am not responsible for the
hardware design :-)
I guess you found the issue: The lower data lines are connected. I guess the
designer of this hardware did not have the schematic of the camera and assumed
that the numeration of the data lines of the camera module is the same like on
the MT9M131 chip - which does not seem to be the case.

Not so far but I just tried. The JPEG compressor does not seem to like it but I
can import the raw frame as ARGB into i.e. ImageJ and what I get is a RGB image
with quite a lot of overflows and wrong colors. It looks pretty much broken like
I would expect it to look missing the upper bits.
I'll see if I can fix the hardware now :-)
Greetings
Florian
