Hi qwitza,

We use an Arria 10 device. But I think the HPS and Ethernet part is quite similar to the Cyclone V. As you already found in this forum, we had an issue which looks quite similar to yours.

After many tests and debugging I fond a solution which works for the moment. I never found the exact root cause of the issue, but it works with the following software releases:

u-boot: 2021.07

Linux Kernel: 5.10

Fact is, that in my case an update just of the Linux kernel was not enough! I really don't know the root cause, but it seams that this combination of u-boot and kernel works.
