thanks, so this is clear now..

no, I don't have the 10369 interface board.

so far I don't have the dev toolchain either. I'm looking here:
http://wiki.elphel.com/index.php?title=Elphel_Software_Kit_for_Ubuntu

while I'm finding detailed information for the toolchain (gcc cross-,
compiler, etc.), I'm not finding info here on how to boot the camera
over the network.. where would I find such information?

yes, I tried to plug in the camera into a 10/100Mb/s hub, and also
directly into the laptop's RJ45 connector - which is auto-sensing for
detecting a cross-cable setup. Unfortunately I got the same results :(
