ESP32 - Wiznet W5200 problem

[victorsonntag]

Hi @khoih-prog ,

Thanks for your great code!
I am working on a project (http webserber on an esp32 WROOM) and I use your great library. It is works perfectly with w5500 (wiz850io), but when I use with w5200 (wiz820io) the Ethernet.hardwareStatus() come back with 'EthernetNoHardware' value. The same setup and code works without any problem with 'ethernet.h' library. I compared the two library and I found a difference in the init() void. In your code there is an extra 'softReset()' command, which is not in 'w5100.cpp'. After I commented out, the problem is solved.
I don't know why it's causing problem on w5200, but I hope this information helps you to fix this bug.

Please let me know if you need any further information!

Hi @victorsonntag

Thanks for the good investigation and info.

I actually never have and use W5200 as it's so unpopular and don't know where to buy. The library was then tested with W5100, W5100S and W5500.

Thanks to this fix, I'll make change in the new release to support W5200.

I'd appreciate if you can make a PR, I'm so busy now.

HI @victorsonntag

Are you sure you're using this Ethernet_Generic library and the latest version v2.6.0? I can't find anywhere in the library the mentioned init() using softreset()

If you mean this

Ethernet_Generic/examples/WebClientRepeating_ESP/WebClientRepeating_ESP.ino

Line 100 in f8fa933

Ethernet.init (USE_THIS_SS_PIN);

then you have to change it to use the correct CS pin, according to your wiring.

Do you mean this line, in w5100_Impl.h

Ethernet_Generic/src/utility/w5100_Impl.h

Line 331 in f8fa933

softReset();

[victorsonntag]

Yes, this is the one
