Are you debugging over the network as well? Or over serial? 

I have sometimes seen instances where GDB or the GDB stub has not placed
the next breakpoint (used for the stepping) in the right place. If your
program just continues rather than stops dead that may be what it is, and
to fix it requires you to debug it.

Okay... assuming you had a reason to do this.

You got a bootp reply even though you told it not to use bootp? Are you
sure you saved the configuration and rebuilt both eCos and the test?

Hmm.....

This is the ICMP code for echo, not echo reply.

I thought the BOOTP debug output was meant to display the local address,
i.e. not FF:FF:FF:FF:FF:FF:FF. Do you know if your board has a serial
EEPROM for the ESA? If not, you will need to set a MAC address for the
board in the eth driver config.

Does ping_lo_test work?
