Hello everyone!

I have a problem with compiling examples of rtems-libbsd. I just do not 
know how to do it. I have the example (Testsuite/ping01/test_main.c) . 
This is the report of terminal when I executed it:

## Transferring control to RTEMS (at address 00104040) ...
nexus0: <RTEMS Nexus device>
cgem0: <Cadence CGEM Gigabit Ethernet Interface> on nexus0

3 paassertion "exit_code == EXIT_SUCCESS" failed: file 
"../../testsuite/ping01/test_main.c", line 57, function: test_ping

I want to change the IP for ping to my PC. It is in the file 
But I never used Waf before. ¿Where is the makefile for the suitables 

By the way, I'm working on a zedboard and I'm trying to make Ethernet 
connectivity work. (If someone has a little manual I would appreciate 

Thank you in advance

And thanks Sebastian, you were right.
