how to generate lwip working code stm32f767zi(nucleo 144) using stmcube ide

Sudheesh_Unnipillai · ‎2025-03-26

I tried to generate code using stm32cube ide to run lwip and tried to ping the board. But it is not working. Is it possible to generate code that runs without any modifications in the generated code?

No. That's impossible. You need some configurations to set in CubeMX or in the CubeMx embedded in CubeIDE.

You need to set the RAM used by the ethernet Tx/Rx descriptors, as well as the LWIP heap with the MPU configuration.

You can refer to this article for STM32H7 product.
