Hi Sir,

       This is shiva chary ,am trying to implement Ethernet without LwIP,so when am configuring the ethernet MAC it is not resetting and am getting timeout error. can u please provide the solution for the respective error

Thank you

regards,

    Hello @shiva_chary  , 

    For Ethernet implementation on STM32, we strongly recommend using LwIP. It provides a reliable and well-supported TCP/IP stack . 

    Please consider using LwIP for a smoother development experience. Also, I suggest checking this article — "How to create a project for STM32H7 with Ethernet and LwIP stack working" — which can be very helpful for your project using the same board  STM32H750-Discovery .

    Hello,

    In addition to what @MOBEJ said you can also refer to this article: How to create a bare metal HAL Ethernet application on STM32H563/STM32H723

    This implementation is using only HAL no ethernet stack needed.

    Why?

    Doing that requires that you have a deep understanding of both TCP/IP networking and the hardware implementation on the STM32H7.

    The whole reason that things like LwIP (and other TCP/IP software stacks) exist is that this level of understanding & experience is not common - they exist so that you don't have to get bogged down in these arcane details.

    So you'll need to debug that issue.

    The solution, if you're not able to debug at this level, is to use a software stack - such as LwIP.

    other stacks are available.
