Honored Contributor88E1111 Marvell PHY Chip Clock
Hi Friends. This post is about Marvell 88E1111. It's close to impossible getting any information from them. On connecting the 25MHz crystal to the XTAL1 and XTAL2, does the chip internally...

Honored ContributorWell, after new experiments I solve some of my problems) I understand that I was use signaltap analyser with wrong trigger configuration. Thats why I see nothing at receive path. After configurating triggers, I was convinced that Phy recieve all packets at Ethernet line and send it to TSE MAC.
So this is great! But there are still some problems with transmit UDP packets. Wireshark at my PC correctly capture at Ethernet line any UDP packets from FPGA with destination MAC - different than MAC of my PC network card. UDP frame with broadcast destination MAC appears at Wireshark. But when I set as destination MAC from my PC, Phy transmit LED Blinking, Signaltap show at MII line correct frame, but Wireshark show nothing (I tried to capture traffic with CommView, but its all the same). UDP with correct destination MAC missing. So I don`t understand how this can be, I suppose that I missing something importatnt, but I don`t know what =(.
