Unable to Obtain IP Address - Simple Switch Example (IDFGH-13381)

[Ben-Rosenfeld-VPS]

Hi,

I'm running the simple switch example and trying to follow the setup instructions. I have a PC connected to one port of the KSZ and a Netgear switch connected to the other port of the KSZ. In the logging, I am able to see the link up when I plug in the PC and the Netgear switch to the KSZ and ESP:

I am also able to see the Mac Addresses of all the devices:

However, I never see the Got IP Address log message:

I also used Wireshark on my PC but I never see these messages originated from the ESP:

Are there any suggestions you can make for us to debug this issue of not receiving an IP or transmitting data? We have connected a logic analyzer to the SPI bus of the KSZ and analyzed the data and it appears OK. Here is the configuration:

Any suggestions are appreciated. Thank you.

Could you please send full log?

Just this you mean?

Try to increase log level to "debug" and observe for "receive len= to see if you are able to receive data at least. You can also change log level directly at https://github.com/espressif/esp-idf/blob/release/v5.2/components/esp_eth/src/esp_eth_mac_esp.c#L297 to not pollute the log with other debug messages.

Thank you for the guidance. We have narrowed the issue down to the following RMII Clock Selection bit needing to be set to 1 (internal) instead of the default (external):

We thought that would be this setting but with this set we don't believe Bit 3 in Register 0xC6 is being set?

This is the difference between the example schematic and our schematic:

[Ben-Rosenfeld-VPS]

It seems we did just need to change that dropdown - is that all that is required from your expertise? Thanks!

[kostaond]

So there is no issue in the driver if I understand it correctly. You just selected incorrect option at the start, am I right? The CONFIG_EXAMPLE_P3_RMII_CLKI_INTERNAL is default.

[Ben-Rosenfeld-VPS]

We are testing now but will close this for now. The assumption is that it will work properly with the kconfig change.
