cant ping nucleo-h723 dev board using lwip

Question

HiI am trying to develop a board based on ethernet connection. I have bought a nucleo-h723z board to get started.I would like to have a ping example up and running, but I have not succeeded...I am using CUBEIDE V. 1.15.1 and CUBEMX V. 6.11.1.I have carefully followed the article of: https://community.st.com/t5/stm32-mcus/how-to-create-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308#memory-layout.However, I am not using RTOS, hence those parts are skipped. I am aware of the smaller D2 RAM capacity of the h723 chip.I have checked the pin generated by CubeMX with the nucleo schematic.Debugging reaches main-loop, but when pinging I get "destination host unreacheable". I am on the same subnet etc from my PC.my main file:  /* USER CODE BEGIN Header */

Hello @DavidWahlberg ,I recommend you check the following Example STM32Cube_FW_H7_V1.11.0\Projects\NUCLEO-H723ZG\Applications\LwIP\LwIP_TCP_Echo_Server\ as a reference because at first glance you are missing some necessary steps and the MPU config as well is not in line with the example. BR
