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