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.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
