From the diagnostic results cited above it looks like the problem is in your host: the tagret sends 7 ARP requests which are decoded correctly (I assume this because neither you nor you host complain about ARP requests contents), but host doesn't respond to them. I would check the ARP requests contents and then your host settings. Best regards, Andrei Shamile Khan wrote: > Hi, > > I have a Memec FG456 evaluation board with P160 module.
