I using example.
It can not get dhcp ip from router.
I verify same cable to pc. It can get dhcp.

How to solve it ?

I have not tested with your particular pins, but this sketch works fine on our end. I use it almost daily. Can you verify the pins? Also maybe try removing the pull-ups and capacitor from the IRQ line?

This sch, I copy from another product ( Deploy more 5,000pcs ) , But it using IDF.

You are using IDF now too. Just abstracted to Arduino

I not responsible about that project idf.
And this project prefer Arduino IDE

[me-no-dev]

What I am trying to say is that Arduino is also using IDF so the code should work and it does work for us. We have tested W5500 quite a bit. This is from the latest 3.0.0-RC3:

What is your hardware ?

Hello @sirapol

I tried your code verbatim and for me it works too - the W5500 gets an IP address just fine.

I noticed that in your schematic TOCAP (W5500 pin 20) is connected to C13 which is a 10 nF. According to the specifications (see here) it should be a 4.7 uF capacitor.

20 TOCAP - AO External Reference Capacitor
This pin must be connected to a 4.7uF capacitor.
The trace length to capacitor should be short to
stabilize the internal signals

Thanks
Felix

This sch, I copy from another product ( Deploy more 5,000pcs ) , But it using IDF.

Wrong circuit design does not get corrected by amount of build pieces ;-)
The wrong choosen AO External Reference Capacitor does harm.

[TD-er]

Also another design tip for future designs...
You should separate the power nets for the Ethernet chip and the rest. In your schematic snippets they seem to be using the same nets. (GND and 3V3)
So have a single location where both GNDs are connected using for example a beefy 0 Ohm resistor to connect both GNDs and use a ferrite bead to separate both 3V3 nets.

It will most likely not cause these issues (wrong capacitor is more likely as pointed out by others), but it will make it more likely the CE testing will pass without issues.

Also please look into how the metal shield of the RJ45 connector is connected to the rest of the nets.
There is lots of info online about this. Just to be sure there won't be any issue when someone is using Ethernet cables with shielding.

[sirapol]

After i change C13 to 4.7uF. I error more.

[TD-er]

Maybe a closer inspection of the W5500 chip to double check it isn't a W6100 or W5100 or some clone?

[Jason2866]

Maybe using the 4 GPIO mode stabilizies your setup.
Just connected a dirt cheap diy W5500 module to an ESP32-C3 (via Dupont wires!!) and it is working rock solid this way.
