From my experience with uBoot, you cannot ping a board running uBoot,
as uBoot does not listen for pings. You can however ping a PC from the
board running uBoot.

Hello
With the Roach1 in the uboot state. Network address (192.168.3.240)
acquired via dhcp, from a directly connected windows+cygwin
PC host system (192.168.3.2).
Roach1 can ping the PC exactly as expected.
PC cygwin ping of Roach1 hangs.
While PC ping is hung if the Roach1 pings an unused address
say 192.168.3.3 then the PC pings of the Roach1 un-hang and
return just as expected. When the Roach1 pings give up
after the N failures the PC pings return to the hung state.
I speak under correction, but I think uboot only brings up the network
when it needs it (uboot isn't an operating system, it doesn't have
interrupts or background tasks).
