STM32F7 and LWIP issue

I'm having issues with ethernet on the STM32F7 discovery and nucleo boards.

I set up a simple Keil project using STMCube by using selecting the dev board when you create the project. I enabled ETH and LWIP and launched Keil.

But upon compiling and flashing (with LAN connected to router), when I go to the router's web interface I don't see an IP being assigned to the STM32. I have checked that the DHCP is enabled in Cube. I suspect that the DHCP is timing out.

Any suggestions?

Thank you.

Hi c.kalhana,

I suggest you to start from the lwIP example under STM32cubeF7 package:

STM32Cube_FW_F7_V1.3.0\Projects\STM32746G-Discovery\Applications\LwIP

The example guides STM32Cube HAL API users to run application based on Netconn API API of LwIP TCP/IP stack.

For more details about this application, refer to UM1713 ''STM32Cube interfacing with LwIP and applications''
