Re: [lwip-users] LWIP + FreeRtos + STM32 + Optimization Problem

[Dave Nadler]

You haven't said which STM32.
Different series have differing Ethernet drivers, many very buggy.
Have you reviewed: https://community.st.com/s/question/0D50X0000BOtfhnSQB/how-to-make-ethernet-and-lwip-working-on-stm32

Hope that helps!
