Thanks for the answer! I found in your repository example: https://github.com/RT-Thread/rt-thread/blob/master/bsp/stm32f40x/drivers/stm32f4xx_eth.c. But he did not want to work on my development board. I used module ETH (DP83848). You could not say what the main places I need to fix? I am very grateful to you!On 29 May 2015, at 15:24, bernard <bernar...@gmail.com> wrote:Hi Sasha,I didn't have a web server example. I think you can port the http server example from lwIP.
