ADIN2111 no Link with Overlay and ADI-Kuiper

Thread Summary

The user experienced issues with the ADIN2111 Single Pair Ethernet Evaluation Board where the link status would briefly become active and then drop. The problem was resolved by shortening the SPI cable. The engineer also suggested checking the output of 'ip addr' and the content of '/boot/config.txt' for further diagnostics.

Good day,

I am using ADI-Kuiper with the rpi-adin2111 overlay to connect an ADIN2111 Single Pair Ethernet Evaluation Board. The interface seems to be connected correctly.
However, I have a problem with the link status.
When i use dmesg | grep adin to output the kernel messages, I see that the link becomes active for a short time, but is immediately switched off again.
I used this tutorial wiki.analog.com/.../adin2111_linux_quick_start_guide

Output:
adin1110 spi0.0 adin2111-0-p0: Link is Down
IPv6: ADDRCONF(NETDEV_CHANGE): adin2111-0-p0: link becomes ready
adin1110 spi0.0 adin2111-0-p0: Link is Down

Does anyone have an idea or solution for the problem?
