Hi Jack: I modified the vivado version from 2018.2 to 2018.1 in a file under cont_microblaze. The compilation is fine and completed. Bitcodes are generated. I have the UART output as following. My problem is the DHCP i guess. Looks like the DHCP didn't work. Usually, the led right next to the RJ45 port should be flashing for some time, but in my case, that led was so quiet. I have the dhcp running at computer side. Did i do something wrong?
