Enabling Ethernet Interface on Nucleo-H743ZI2

Hi,

I am developing a TCP/IP server for my application on the Nucleo-H743ZI2 board. I want to use LWIP with FreeRTOS to allow threading and have a similar syntax to POSIX sockets.

So far I found the following two examples:

(1) This tutorial targets the same CPU family STM32H7 but a different board. https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working

(2) An example in STM32 Repository in the following path: STM32Cube_FW_H7_V1.8.0\Projects\NUCLEO-H743ZI\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS

However, this example does not use CubeMX which is extremely important in my case as I use it to manage many interfaces in my project (QSPI, I2C, ADC, etc)

I followed the first example steps and I adapted some stuff based on what I found in the source files of the second example. However, I could not ping the board at all. I attached project files (Test_Ethernet).

Here are the steps that I've done (I attach snapshots at the end):

1. Created a new project on STM32CubeIDE 1.4.0 using STM32Cube_FW_H7_V1.8.0.
2. Started configuring the project using the embedded CubeMX in CubeIDE.
3. I select "No" to "Initialize all peripherals in default mode.
4. Here is a snapshot of my clock configuration. I configure the clock to 400 MHz. I also set the high-speed clock (HSE) to bypass mode.
5. Configure the Ethernet interface
   1. Setting the mode to RMII with all the GPIOs maximum output speed set to High.
   2. Enable ethernet global interrupt with preemption priority set to 5.
6. Configure Cortex-M7. Here I enable ICache and DCache with MPU Contro Mode set to Background Region Privileged accesses only. Then, I set two memory protection units as follows:
7. Configure FreeRTOS
   1. Enable the FreeRTOS with CMSIS_V1 API.
   2. Increase the size of the default task stack to 256 words.
8. Configure LwIP as in example (1).
9. Add DATA_IN_D2_SRAM to macro definitions in the project.
10. Modify linkerscript as in example (1).

So what am I missing in my steps or configurations?

Thanks
