Hi,

im using the stm32f41ig-eval board an i modified the example: STM32F4x7_ETH_LwIP_V1.0.0/ FreeRTOS httpserver_socket.

After the modification i can send data to the server an it send it back to the client. Than i measured the

throughput

with wireshark and the result is i only got 5Mbit/s throughput.

So i modified the file stm32f4x7eth_bsp and un comment the lines:

 ETH_InitStructure.ETH_Speed = ETH_Speed_100M;

 ETH_InitStructure.ETH_Mode = ETH_Mode_FullDuplex; 

but after that i havent yet the 100Mbit/s.

So what can i do to get the 100Mbit/s?

Oh and my computer I have checked he is configured for 100Mbit/s.

please be kind to me i not a native speaker.

Thanks

Ingo
