타겟보드는 STM32CubeIDE를 사용하여 다운로드와 디버깅이 가능한데, Eclipse로도 컴파일/다운로드/디버깅이 가능한지 확인해봄.

LED Port 번호

Mbed Studio에서는 NUCLEO144 STM32H743ZI2를 지원한다. 소스를 보면 아래와 같은 부분이 있다.

• {Project Root}/targets/TARGET_STM/TARGET_STM32H7/TARGET_STM32H743xI/TARGET_NUCLEO_H743ZI2/PinNames.h

    // Generic signals namings
    LED1        = PB_0,  // LD1 = GREEN
    LED2        = PE_1,  // Yellow
    LED3        = PB_14, // Red
  

  User Input ==

    // Standardized button names
    USER_BUTTON = PC_13,
    BUTTON1 = USER_BUTTON,
  

Eclipse 버전

링커스크립트 수정

STM32CubeIDE에서 사용한 ld파일을 참고하여, mem.ld파일을 수정

프로젝트 생성시

   * the the specific requirements of your hardware. The zero
   * length prevents inadvertent allocation.
