LAUNCHXL2-RM57L: lwip on RM57 launchpad

Part Number: LAUNCHXL2-RM57L

Hello,

           I am trying lwip on RM57 launchpad.

I am in a situation where the RM57 is able to receive ethernet packets but doen't transmit anything.

If I send a ping I can see that the launchpad goes into "replying to ARP request for our IP address" but I don't see any packet going out (I am using wireshark).

The strange thing is that the 2 counter in the ISR routines: countEMACCore0TxIsr and countEMACCore0RxIsr are "0" in the beginning but than always have value "1" as the ISR routine is executed only one time. Is this normal?

Any help is welcome

Errico
