No Ethernet Link on Pico Ultra

I have a Pico Ultra w/ PoE that I have flashed with both Ubuntu and buildroot. In both cases eth0 is available, however it does not get a link on the switch.

Is this a hardware issue, or configuration? I have reflashed the device multiple times with no change in behavior. The device does power up via PoE, however does not get a link - I have also removed the PoE adapter with same results.

I think it may be a hardware problem, you can check through our wiki, POE module requirements for switches, please check if your switch meets the requirements. https://wiki.luckfox.com/zh/Luckfox-Pic ... kfox-Pico- Ultra-W/Luckfox-PoE-Module

Thanks for the feedback.

I just got a replacement Pico Ultra today which is working fine, so expect the previous one had a hw problem. Not yet tried PoE on the new one, but at least Ethernet works on it. Thanks!
