Hello
I'm trying to run the Ethernet project "basic"
I get the following error:

The error is: 'lan8720: lan8720_init(429): wrong chip ID'. Are you sure you're using the correct PHY and that it's wired up OK?

OK the problem was that I needed to power on the Ethernet. I have a custom board with esp32
Sorry my fault
But now I have another problem. I don't get an IP address
This is the output

I have another custom board with an ethernet and the fw in there works fine. So, hw wise it should be fine. I flashed the example to that board but it's failing as well. So, the problem is probably sw not hw

Here are my configurations
I didn't change or add any other configurations other than the defaults in the example

Could you please share more information about your "custom board with an ethernet and the fw in there works fine"? I couldn't say if the shared SW configuration is correct without knowledge of actual HW design.

Thanks

I have a project would using Ethernet. And I try the example with en28J60. Everything is OK. Here is the serial output.
---------------------------------------------------

-------------------------------------------------
So is there any problem with your board. If you are not sure, I suggest using 28j60 phy with official example instead of custom board.

Well, ENC28J60 could certainly do the job but I would strongly discourage everybody from using it for any new design. See the reasons why:
1) It supports only 10 Mbps
2) It has bunch of errata, I tried to address them in the latest example update, but still...
3) And most importantly, it has crazy power consumption which may cause chip instability if you use improper powering. See here for more information. In addition, power consumption should be a concern in general for any IoT solution.

Thanks for your information, ESP_ondrej.

I will try 8720 and 83840 again with basic example.

Yes, it is correct. Now you can try "ping 192.168.1.37"
