Sorry i'm not too familiar, with all of this maybe i make false assumptions...

Yeah there were a few things, getting all the interupts out of the V4 was a pig (hacking the serial port to output int2 for example) and a lot of other similar things which may not have stopped the card working on its own but overall it just didnt work.

So you need someone "fixing"/re- designing your FPGA glue logic, or wasn't there any? I think there is something in this direction on the Coldfusion card is it?

Did you try to "initialize"/boot up the card with the Freescale CF68k lib? Otherwise the Design may actually be fine, but the whole thing could have become stuck in Kickstart.

Would be interesting to hear something more specific, i really like the idea of ColdFusion, but unfortunately it seems to be a big problem to realise it.

would a dual-cpu accelerator be possible?

It surely is possible (at least it was with PPC...) but it is an expensive solution as you need an additional 68k CPU to the Coldfire and will end up with more traces, a bigger board or a PCB with more layers. :-(
