Running a WIZ550io (SPI Ethernet Module with W5500 chip)

[EarthAndy]

I am attempting to get a WIZ550io module with a ESP32-S3 (ESP32-S3-DevKitC-1-N8R2) running with the ESP-IDF 5.1.2 API.

https://www.wiznet.io/product-item/wiz550io/

I started with the esp-idf\examples\ethernet\basic project. I was able to configure the project to my IO (which was basically the same as the defaults for the project), and compile/flash. The project runs, appears to communicate with the W5500, gets a Link status, and then never gets an IP:

Code: Select all

I (339) main_task: Calling app_main()
I (359) esp_eth.netif.netif_glue: 4a:27:e2:66:2f:08
I (359) esp_eth.netif.netif_glue: ethernet attached to netif
I (369) main_task: Returned from app_main()
I (369) eth_example: Ethernet Started
I (2369) eth_example: Ethernet Link Up
I (2369) eth_example: Ethernet HW Addr 4a:27:e2:66:2f:08

I can unplug and re-plug the ethernet cable, and the the lights on the module act accordingly (and the example program shows the status as the link goes up and down, so I assume there's proper communication and interrupting happening with the device:

Code: Select all

I (146369) eth_example: Ethernet Link Down
I (150369) eth_example: Ethernet Link Up
I (150369) eth_example: Ethernet HW Addr 4a:27:e2:66:2f:08

Eventually I start to get a bunch of errors on the output:

These errors repeat indefinitely.

Now, I know that the default IP and Gateway of the WIZ550io (and W5500 chip directly) have default settings that will not work on my network - I'm on a different subnet. So I set up an SPI interface so that I could change the registers on the W5500 with my own network settings, however that did not change the outcome. I have had some trouble getting the W5500 to keep the settings, but that shouldn't be affecting the current state of my system:

After a few seconds (15 or so?), the system starts reporting the same errors as above.

I was hoping to get some direction on how to address these issue, or if I need to be looking at the WIZNet forums, or the W5500 chip folks.

Thanks in advance.

[DrMickeyLauer]

Try increasing the log level verbosity to DEBUG to see some more information. Which SPI-frequency do you use? Is this a custom PCB or a breadboard? I have noticed breadboard installations being very sensitive to high SPI frequencies.

[ESP_ondrej]

There probably is some issue with SPI as @DrMickeyLauer mentioned.

1) Check the GPIO configuration once again. Ensure INT pin is connected too.
2) If custom board is not used and just wires are used, use wires as short as possible and with matching length.
3) Decrease SPI frequency to e.g. 4 MHz. Note that we are able to run W5500 at 40 MHz but it requires properly designed PCB!

[EarthAndy]

Thanks for the direction, folks!

I am (was) using a the two modules on a breadboard just hooked up with loose 20cm plug wires. I took the time this morning to cut some solid-core copper wires, to length, and re-wired the SPI runs.

I was able to get the ethernet/basic project to build and connect and get an IP the first time I fired it up - so clearly the issue was my loosey-goosey wiring. I had been trying to get it going at 4MHz, but just as a test added a zero and got it to get an IP at 40MHz. Once my PCBs come in, it looks like it won't be an issue.

I pulled the module into my main application and swapped out my WiFi bits and got my MQTT publisher up and working over ethernet without too much issue.

Appreciate the help!
