Having problems to communicate with uClinux on the board with a default
kernel, I wonder if somebody has an idea of what happens.

My board is configured with ifconfig and route as discribed in
uClinux/coldfire website.

I can ping my host from the card and the card from the host but no other
ip services does work.

With ifconfig, I can see that packets are exchanged but the services
don't work.

I wrote a simple socket client/server and try to exchange between my
card and the host, in both way, but no result.

I've try tcpdump on the host but it is hard to interpret. 

The only thing that differs is a wscale.

I've search the forum but no result.

Could it be a problem with config of the interruptions.

On start, the print is (uClinux 2.4):

PS: I've tried tftp from the eval board to the host and it works but
very slowly.
