eth_phy_802_3: esp_eth_phy_802_3_reset(140): reset timeout

[Graceful-Massana]

I'm trying to connect an ESP32-PoE-ISO-WROVER using ethernet with a fixed IP following the examples.

I'm getting this error:

E (624) eth_phy_802_3: esp_eth_phy_802_3_reset(140): reset timeout
E (624) eth_phy_802_3: esp_eth_phy_802_3_basic_phy_init(435): reset failed

Can't say much without also looking at your program. Some things to check is whether you are providing the correct pins. Those which are hard-coded you cannot get wrong, but for example rmii_mdio and rst are NOT hard-coded. Are you configuring those correctly, according to this schematics?

Copy-paste from here as to what you need to use.

Just uploaded my code here .

I sent an email to Olimex and they advised to not use gpio12 as reset because it's meant to power PHY, but I'm still getting similar errors:

Did you read my two previous comments? Did you check- in their own C example - what pin they use for "reset"? Did you also check this in the schematics?

I hope you understand, that you can't just pick a free pin for "reset"? You have to use as a reset pin the exact pin, which - on their schematics - is connected to the reset pin of the phy.

Ditto for rmii_mdio.
