im stuck anyone got any clues what to do?

ive double checked the jumpers, moved the stacking cable around, but no luck, what am i doing wrong?

cheers..

Sounds like you didn't update the firmware.

Oh and be extremely careful with the micro usb jacks. One if mine broke clean off when I first disconnected it. (cold solder joint? the whole area looks quite matte and rough)

Fortunately this happened after updating the firmware, so the board runs over the CANBUS just fine. Of course that means I’m stuck with this firmware, but it seems to work flawlessly so far.

If you look really closely, you can see the micro usb-jack and PCB flex an awful lot from just the weight of the cable alone.
It is probably a good idea to zip-tie the cable to one of the bolts for strain relief. (Zugentlastung  Wink)

I chose micro-usb because they are tougher then mini-usb plugs, and they through hole, must have been a real bad solder joint there.
On my boards here none of the connectors flex at all.
