ESP32C6+USR-ES1 module - randomly shutdowns the RJ port

seyyup — Sun, 22 Dec 2024 12:42:52 +0000

Hello Gents,
I'm facing continous - and pretty annoying - issue. I've connected the USR-ES1 W5500 Ethernet module to the C6 Shield. There's no way to connect it the wrong way (well, maybe excepts upside-down - but the port is facing the front of the Shield). Everything works fine after the firmware flash, it gets na IP address from my DHCP pool, it's accessible through the website, I was even able to connect to it via the HomeAssistant ebusd add-on. But then... after couple of minutes the RJ-45 port on the USR-ES1 module shuts off without any cause. The red diode on the module is still lightning, but the port (including its LED lamps showing the link status) turns off.
It's not reachable, the only way to connect to it is via the hotspot option - after the link cutoff event happens in the configuration tab, under the Ethernet it looks like the USR-ES1 module is not connected to the PCB. The only way to get the link back up is to erase the device and install the Shield again. And the vicious cycle starts from the beginning....
I've checked the C6 logs but there's no errors - even no warnings. Everything looks fine.
I'm pretty noobie in the ESP solutions and I'm seeking for some help. I digged through the Google and found some codes that should (?) be implemented to the ESP32. The question is which one of these codes should really be implemented and what's the way to do so without breaking the rest of the code that's already on the ESP (the factory one).

I will be very grateful for any tips on how to resolve this problem guys. Thanks in advance.
If there's anything that I can provide for the troubleshoot please let me know.
