I thought than once the program start, with nothing more than an empty main and the init phase of eCos, I would have all the necessary threads running for ARP or ping response (at least). If you confirm me this behaviour, that's I'm missing something in my eCos config. Did you add anything in the initialisation phase ? thanks.
