Created a project targeting STM32F4DISCOVERY + STM32F4DIS-BB from a scratch with CubeMX. Managed to blink LEDs and send bytes over UART but now struggling with Ethernet and LwIP. I have referenced STM32F4DIS-BB example and have added PHY reset into generated ETH GPIO function and both LEDs at ETH connector is set on, but when pinging from pc no input interrupts are triggered nor low_level_input() being called. Any ideas or experience is this HW or LwIP configuration problems. Attached is my *.ioc file. Thanks.
