I am currently porting eCos to a board called TQM850 and have used the
existing MBX860 port as a base. 

My problem now is with the ethernet connection. I have mapped all output
pins from the CPU to the external ethernet chip in a way that match the
schematics. However, when i connect the ethernet wire to the board then the
yellow led is always lit. As i understand this means that we have constant
collision on the network. What can be wrong here?

Regards, Daniel
