esp_eth_phy_new_generic() function
Create a PHY instance of generic chip which conforms with IEEE 802.3 @warning While basic functionality should always work, some specific features might be limited, even if the PHY meets IEEE 802.3 standard. A typical example is loopback functionality, where certain PHYs may require setting a specific speed mode to operate correctly.
Syntax
Implemented in ![]()
esp_eth_phy_generic.c:19
Return value
- instance: create PHY instance successfully - NULL: create PHY instance failed because some error occurred
Notes
Default reset timing configuration is set conservatively( @c DEFAULT_PHY_RESET_ASSERTION_TIME_US ). If you need faster response and your chip supports it, configure it via @c config parameter.
