``esp_eth_phy_802_3_reset_hw()`` API Changes
|
|
--------------------------------------------
|
|
|
|
This change only applies if you maintain your own Ethernet PHY driver based on :component_file:`esp_eth/src/phy/esp_eth_phy_802_3.c` common functions. The :cpp:func:`esp_eth_phy_802_3_reset_hw` API accepts only one parameter now and resets the Ethernet PHY with internal timing configuration which is defined during initialization. Previously, the API required a ``reset_assert_us`` parameter to specify the reset pin assertion time. This parameter has been removed.
|
|
|
|
Usage example:
|
|
|
|
.. code-block:: c
|
|
|
|
esp_eth_phy_802_3_reset_hw(phy_802_3);
|
|
|
|
|
|
Removed RMII Clock Kconfig Options
|
|
----------------------------------
|
|
|
|
Removed the following RMII clock Kconfig options from `components/esp_eth`. Clock configuration is now handled exclusively through EMAC config structures.
|
|
|
|
**Removed Options**:
|
|
- `ETH_PHY_INTERFACE_RMII`, `ETH_RMII_CLK_INPUT`, `ETH_RMII_CLK_OUTPUT`
|
|
- `ETH_RMII_CLK_IN_GPIO`, `ETH_RMII_CLK_OUTPUT_GPIO0`, `ETH_RMII_CLK_OUT_GPIO`
|
|
|
|
**Migration**:
|
|
|
|
.. code-block:: c
|
|
|
|
// Before: Configuration via Kconfig
|
|
// CONFIG_ETH_RMII_CLK_INPUT=y
|
|
|
|
// After: Explicit configuration in code
|
|
eth_esp32_emac_config_t emac_config = ETH_ESP32_EMAC_DEFAULT_CONFIG();
|
|
emac_config.clock_config.rmii.clock_mode = EMAC_CLK_OUT; // or EMAC_CLK_EXT_IN
|
|
emac_config.clock_config.rmii.clock_gpio = 0; // GPIO0 for ESP32
|
|
|
|
|
|
**Impact**: Applications using ``ETH_ESP32_EMAC_DEFAULT_CONFIG()`` continue to work. Custom clock configurations must be set explicitly in the EMAC config structure or use the `Ethernet Init component <https://components.espressif.com/components/espressif/ethernet_init>`_.
