I am trying to do ARP request generator on ZCU102 through 10G Ethernet by using 10G/25G Ethernet subsystem which I used xapp 1305 as a guideline. I already test my APR request generator module by using KCU105+10 gigabit Ethernet media access controller (10GEMAC). As a result, ARP request is shown on wireshark on the computer.
When I porting ARP generator module to ZCU102 by using 10G/25G from xapp 1305(by changing from configured by S_AXI to control and status vectors as shown in figure). It can receive packet from SFP but it cannot send ARP request to PC. I have checked connection with pg210 v2.3.
Has anyone worked with 10G/25G Ethernet subsystem with successfully on a ZCU102 evaluation board by configure interface through control and status vectors?

Hi @dnop030, I have verified XAPP1305 10G design on ZCU102 board.
When you use configuration vector instead of the management interface, have you successfully brought xapp1305 design up and running and can you ping from both sides? This will firstly help rule out if it's related to your ARP generator module.

This issue turned out to be because of padding.
Legacy 10G core pads packets to minimum sized(64bytes) packets as per the standard and in new 10G/25G Subystem users need to pad the packets to minimum length.
Issue is resolved after adding the padding bytes.
