IDF 4.2 basic example fails

[Scott.Bonomi]

After Zipping my 4.0 configuration I cloned from https://github.com/espressif/esp-idf/tree/release/v4.2 as I have read in the forum it works with Eclipse and JTAG.
After getting it and running install, I copied the basic ethernet example up to the esp-idf root and told idf to build it. I even chose to flash it directly and let the new monitor feature show it executing, or NOT. It apparently died at line 125 on the call to esp_eth_driver_install().
The device is a U4WDH on a DevKitC, with single core and 4M set in the configuration.


So what did I do wrong?

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

idf.py build

[ESP_Angus]

Hi Scott,

Code: Select all

E (568) emac_esp32: emac_esp32_init(308): reset timeout
E (568) esp_eth: esp_eth_driver_install(198): init mac failed
ESP_ERROR_CHECK failed: esp_err_t 0xffffffff (ESP_FAIL) at 0x400837e0

This error indicates that the ESP32 is failing to initialize the ethernet interface. Most of the examples use the ESP_ERROR_CHECK macro which will call abort() if an error is returned from a setup function.

Can you give any details about the ethernet PHY you have connected to your development board? The README has some pointers about which PHY models are supported and the pin assignments.


PS

I copied the basic ethernet example up to the esp-idf root

Just as an aside, you shouldn't have to make any changes inside the ESP-IDF directory itself in order to build an example. You can build it in-place, or you can copy it somewhere outside the ESP-IDF directory in order to use it as a basis for your own project.

[ESP_morris]

"emac reset timeout", seems like esp32 internal Ethernet MAC doesn't get a valid RMII clock.

Can you describe your hardware design, like what's your PHY chip, how it connects with esp32, where the RMII clock comes from, etc..

BTW, have you read our documentation about ESP32 Ethernet here: https://docs.espressif.com/projects/esp ... p_eth.html It covered some hardware design commendation there.
