Thank you for your reply. I've done this exactly but I still have a problem running the
ping_test example.
There is no session trace:

I then had a look at the configuration file.
Below is the part of the "ecc" file related the network
drivers. All variables related to the NET_DRIVERS are assigned
a 0 value.
In the (Windows NT) eCos Configuration Tool, the items Initialization
options for 'eth0', are greyed out, and thus can't be
modified.
Do you have any hint about what I'm doing wrong?
