    • CubeMX + OpenSTM32 + lwIP + FreeRTOS not working

    Posted by adibacco on 2017-11-26 00:29

    I just created a simple project with CubeMX including FreeRTOS and lwIP. I selected STM32F746G-DISCO board and enabled Ethernet in RMII mode.
    Then I generated code for SW4STM32 and the project compiles fine but there is no ping.

    Is it possible?

    Found the solution:

    CubeMX configures a wrong value for PHY address. In CubeMX, under Configuration tab, select ETH and set a PHY address equal to 0.

    PHY address should be zero for STm32F746G-DISCO
