lan8742_status_t lan8742_hardware_reset ( lan8742_obj_t * pobj )

Perform a hardware reset of the LAN8742 PHY using the IO layer.

Parameters :

lan8742_status_t lan8742_get_phy_address ( lan8742_obj_t * pobj , uint8_t * paddr )

Get the current MDIO PHY address used to access the LAN8742 device.

Parameters :

  • pobj – [in] Pointer to the LAN8742 component object.

  • paddr – [out] Pointer to store the retrieved MDIO address (0..31).

Return values :

LAN8742_STATUS_OK – on success, LAN8742_STATUS_ERR_INVALID_STATE if called in invalid state, LAN8742_STATUS_ERROR otherwise.

Set the MDIO PHY address used to access the LAN8742 device.

Error handling contract:

  • Any error different from LAN8742_STATUS_FATAL guarantees “no side effect”: the PHY address is unchanged both in the IO context and in the PHY SMR register.

  • If LAN8742_STATUS_FATAL is returned, the driver instance is no longer reliable. The caller must deinit and reinit the driver.

Parameters :

  • pobj – [in] Pointer to the LAN8742 component object.
