ETH H755 Nucleo Hard Faults

Hi Everyone, I've followed STguide on Ethernet on H755 using RTOS

https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308/page/2/show-comments/true

and a github on ETH on bare metal (my case)

https://github.com/AngryCarrot61/NUCLEO-H755ZI-Q_003_ETH?tab=readme-ov-file

 

i got the board to work and ping, I've implemented MPU and connected it to a laptop

DHCP is disabled, my laptop ip is 10.0.0.100, subnet 255.255.255.0, gateway 10.0.0.1

the mcu ip is 10.0.0.60

The ping works only if i flash the M4 core with an empty application which gets halted by the HSEM (it never works unless i flash the M4 first after power up) and the connection never lasts more than a minute.

 

Looking for some help, i've included the whole zip file of the project if someboy could replicate it on their machine, i'm using a H755ZI nucleo board

The problem seems to be releated to Rx heap size, but I'm lost
