Hello everyone,
I’ve been using the W5500-EVB-Pico board by connecting it to an Ethernet switch. Generally, I don’t encounter any issues (maybe about 80% of the time). However, occasionally, even when everything seems to be correct, I get a “cable not connected” error. Resetting the Pico using the onboard reset button doesn’t resolve the issue. Cycling the Ethernet connection also doesn’t solve the problem. Cutting off the power to the switch doesn’t help either. Strangely, if I cycle the power of the Pico, the issue is resolved.
I suspect that the Ethernet chip might not be resetting initially. I have several original W5500-EVB-Pico modules on hand. I’ve swapped the module 4-5 times, but the same issue persists across all of them. It doesn’t seem to be a fault with a specific module.
The software I’m running is the webserver.ino file from the examples, untouched and in its original state. I only removed the comment markers before the “Ethernet.init(17); // WIZnet W5100S-EVB-Pico W5500-EVB-Pico W6100-EVB-Pico” line. I haven’t made any other changes.
Any insights into what might be causing this and how I can resolve the issue would be greatly appreciated.
Thank you in advance!
