Driver for PHY LAN8740A?

Is there a driver for LAN8740A Ethernet PHY?
If not, is there any How-to for creating new driver for Network Component Ethernet PHY?
I would like to use this driver with STM32F207

I just adapted the ETH driver for 32F407 with PHY LAN7420.
Give me your email and I send it.

Hi Georg.

I'm using LAN8740A transceiver with STM32F417 uC and I've some problem with 100Base-TX mode. (10Base-T work fine...).

Do you have some suggestions? You have also a driver for this transceiver ?
Thanks a lot.

Try to change code for 100M register setting in following way:

/* Check the link status. */
    for (tout = 0; tout < 0x10000; tout++) {
      regv = read_PHY (PHY_REG_BSR);
      if (regv & 0x0004) {
        /* Link is on, get connection info */
        regv = read_PHY (PHY_REG_PSCSR);
        if (regv & 0x0010) {
          /* Full-duplex connection */
          conn |= PHY_CON_SET_FULLD;
        }
        if ((regv & 0x0004) == 0) {
          /* 100Mb/s mode */
          conn |= PHY_CON_SET_100M;
        }
        break;
      }
    }
