W5500-EVB-Pico-PoE in Bootloader / Thonny

Question

I got two W5500-EVB-Pico-PoE boards , Rev. 1.1, without the WIZPoE-P1. Unfortunately, I can't connect them to my MAC computer in bootloader mode (pressing the bootloader button while connected via USB-C). Neither board appears as a drive. Thonny, for example, doesn't detect the boards as an interface under any circumstances. I've connected other boards (e.g., Raspberry Pico or W5500-EVB-Pico) to analyze the problem, and they appear as drives on the computer without any problems and Thonny works fine as well. Is there anything special to note with the W5500-EVB-Pico-PoE?

Hello, May I ask how you are currently connecting the board to your Mac PC? I recommend trying to connect it through a powered USB hub, preferably using a USB 2.0 or lower port. If the issue persists, please don’t hesitate to reach out again. Thank you.

Thanks for the update. I just tested a W5500-EVB-Pico-PoE Rev. 1.1 board (without the WIZPoE-P1 module) on macOS, and it worked without any issues. Holding down the BOOTSEL button and connecting the board via USB mounted it as a USB drive normally. Could you please double-check the following? Are you using a USB-C cable that supports data? (Some cables are charge-only and won’t allow USB recognition) If possible, try connecting to a Windows PC Make sure to press and hold the BOOTSEL button before connecting the USB cable, and keep it held for a few seconds Check whether the power LED turns on when the board is connected If you’ve already tried all of the above and both boards still don’t respond, there may be a hardware issue with the boards. In that case, we recommend contacting your distributor or seller for a replacement.
