Just a note that I am seeing the same problem, also on Cyclone V, but with a different IP block in the FPGA. I'm using the Altera/Intel triple speed Ethernet, which is supported by drivers/net/altera_tse.c driver. With earlier u-boot (tested 2018.03) it worked fine. But with 2020.04 and 2020.07 the system hangs as soon as I do "ifconfig eth0 up". This only happens on cold boot; on warm reboot the eth0 port works fine. Reverting c5f4b805755912a3d2fe20 fixes the problem. Regards, Ralph
