Hi Yunfan, Some debugging suggestions below:

For the RFSoC4x2 the interface is expected to be >`eth0`. By default, the RFSoC image uses DHCP to get an IP address. Meaning, that you will need a DHCP server running on your Ubuntu machine, if it is not already configured this way. To get the IP address for the board you would either monitor the DHPC leases issued from your running DHCP server. Or, you can connect over serial to the board and login and use ifconfig to see the IP address that was assigned to the 4x2. > Then I followed the instruction which is shown in the document: fpga = > casperfpga.CasperFpga(“169.254.24.253”), it gets the problem shows in the > attachment “Connect.png”.

The reason here, again I suspect, is because this IP address is a self-assigned IP address for an interface on your local host machine. Not actually an IP address that is attached to the 4x2. > > Sorry for asking the ethernet and board connection problem, I am not familiar > with the network issue.
