I think I found an error in the ethernet HAL for the STM32F4 , can you confirm ?

[HSant.1]

The code after the LAN speed auto detection is this :

line 443 @stm32f4xx_hal_eth.c

  if((phyreg & PHY_SPEED_STATUS) == PHY_SPEED_STATUS)

  {  

   /* Set Ethernet speed to 10M following the auto-negotiation */

   (heth->Init).Speed = ETH_SPEED_10M;

  }

  else

  {  

   /* Set Ethernet speed to 100M following the auto-negotiation */

   (heth->Init).Speed = ETH_SPEED_100M;

  }

I think that the speed selection is inverted, I reverse the values and the interface start working

No, the setting depends on the PHY being used. and the value of PHY_SPEED_STATUS.

Ok, Changing the PHY_SPEED_STATUS solved the problem.

Thanks a lot
