    It means your device is undefined.You need to add a preprocessor symbol to your project.

    If you are using keil.

    Project ->options for target 'project name' -> c/c++

    Then add a symbol STM32F4xx symbol. (Replace the xx with your device type.)

    You can look in stm32f4xx.h file for the options.
