The first ping message should be preceded by an ARP packet which is how
your RedBoot unit discovers the ESA of the PC. Do you see this? Does
the PC reply?

Yes, before the ping query the PC receives an ARP packet with the right ip
address, and the PC replies. Then, the ping query is addressed to the
correct MAC. The PC returns the ping reply to the board's mac, but it does
not seem to reach its destination.

Is your PC on the same LAN as the ADS board (i.e. no router
between them)?
Try enabling network debugging on the device running RedBoot.
Using 'fconfig', set 'Network debug at boot time' to 'True'
reboot and try it again. This will show you what packets
are going through the local network stack.

Hi Salvador.
The debugger on your board may take care of the incoming ICMP reply
before it reaches your application.
I'm not shure, but you might get some note about it if you connect to
the debugger.

Hi
I am using a Freescale i.Mx27ads development board, which contains an ARM9
with redboot installed in it. I have configured a static IP address both in
the board and my PC. I manage to ping from the PC to redboot, but when I try
to do it the other way round a get 100% packet loss. I have all the
firewalls disabled, an Ethereal confirms the PC receives a ping query and it
returns a ping reply, but the board does not seem to receive it.
Any idea?
Thanks
