I plan to learn lwIP based on the tutorials from ALIENTEK (正点原子). The board I'm using is an ALIENTEK stm32f407zgt6 minimum system board plus a LAN8720A for network communication.

The development IDE is CLion, using the open-source embedded toolchain: arm-gnu-toolchain-15.3.rel1-mingw-w64-i686-arm-none-eabi
