Re: [ECOS] How to activate ethernet driver

[Jerzy Dyrda <jerzdy@gmail.com>]

Hello Dennis,

You have to add your PHY driver to the list in
devs/eth/phy/current/cdl/phy_eth_drivers.cdl like that:
    cdl_option CYGHWR_DEVS_ETH_PHY_LAN8720A {
        display       "SMSC LAN8720A"
        flavor        bool
        default_value 0
        compile       -library=libextras.a LAN8720A.c
        description "
          Include support for SMSC LAN8720A"
    }

and after that of course choose it.

Regarding ETH driver you have to provide such entry in an code of driver :

ETH_DRV_SC(stm32_sc,
           &stm32_priv_data,      // Driver specific data
           "eth0",                // Name for this interface
           stm32_eth_start,
           stm32_eth_stop,
           stm32_eth_control,
           stm32_eth_can_send,
           stm32_eth_send,
           stm32_eth_recv,
           stm32_eth_deliver,
           stm32_eth_poll,
           stm32_eth_int_vector);

NETDEVTAB_ENTRY(stm32_netdev,
                "stm32",
                stm32_eth_init,
                &stm32_sc);
after that init() funtion (in my case stm32_eth_init,) will be called.


Best regards,
