ESP-AT LAN8710A Error
Posted: Mon Sep 12, 2022 8:32 pm
Hello,
I am trying run AT-commands firmware for my ESP32-WROOM-32U with eth LAN8710A chip.
In the attachment I am sending the connection diagram: I reconfigured the UART for AT commands to pins compatible with the schematic. AT communication works. I configured the RMII interface with an external clock on pin 17. In the attachment (zip) I am sending the sdconfig and binaries. I am using newest version of idf.py.
This is segment of eth config:
When i send command: AT+CIPETHMAC? i receive ERROR msg. Other commands: AT, AT+DRVPWMINIT etc works.
Please, tell me what i shoud change in sdkonfig file.
