STM32F0X0 Flash Programming

STM32F0X0 플래시 메모리 프로그램을 하려고.. 인터넷을 뒤지니...

대부분 sector 단위로 처리하는 프로그램만 올라와 있어서 혼란스럽더군요..

030을 쓰고 있는데 030은 page 단위로 처리됩니다.

또한 기본 header파일에는 page 단위 어드레스 설정이 안되어 있어서 이부분도 처리해 줘야 하더군요...

일단 개략적인 설명부터......

마이컴마다 페이지 단위가 1kbyte인 제품이 있고 2kbyte인 제품이 있으니.. 적절한 테이블을 찾아서 넣던지 직접 타이핑 해야 합니다. 제가 사용하는 STM32F0x0xC 는 2Kbyte 단위로 페이지가 되어 있고... 2페이지가 1개의 Sector로 물려 있습니다.

ST에서 제공하는 Referance Manual 참조해야 합니다. STM32F030은 아래 링크 참조하시면 됩니다.

위의 레퍼런스 메뉴얼중에도 페이지가 1kbyte로 되어 있는 디바이스와 2kbyte로 되어 있는 디바이스의 메모리 맵에 대한 설명이 있습니다. 찾아보기 귀찮아 하시는 분들을 위해 캡쳐해서 보여드리겠습니다.

1Kbyte Page Size

2Kbyte Page Size

 

메모리를 컨트롤 하려면  일단 main.h에 아래의 내용을 추가해야 합니다... (페이지 단위가 2Kbyte인점 주의)

제가 사용하려는 32F030RCT는 128Kbyte이니 PAGE_127까지 사용하면 됩니다.

플래시 메모리를 컨트롤 하려면 

-페이지 지우기 

-데이타 쓰기

-데이타 읽기

요정도 처리만 있으면 됩니다.

 

일단 억세스 하려는 페이지와 메모리 주소를 지정해줍니다.

페이지는 맨마지막 127번으로 사용하기로 했습니다. 

메모리 주소를 #define으로 지정하는 예제들이 많은데.. 어드레스를 바꿔가며 컨트롤 하려면 변수로 지정하는게 좋겠죠...

또한 읽고 쓰기를 할때 사용할 데이타 변수도 선언해줬습니다. 둘다 32bit.

#define FLASH_USER_START_ADDR ADDR_FLASH_PAGE_127
// STM32F030RCT ENDPAGE ADDR_FLASH_PAGE_127 0x0803F800 ENDADDRESS 0x0803ffff
uint32_t USER_ADDR1=FLASH_USER_START_ADDR +0x00, USER_DATA=0x5a;     // 메모리 주소와 변수선언

 

 

아래는 main.c에 추가 되어야 할 함수와 선언들입니다.

아래와 같이 플래시 메모리 컨트롤에 필요한 구조체를 선언해줍니다.
static FLASH_EraseInitTypeDef EraseInitStruct;

// FLASH메모리를 지우면 그곳에 0xFF값들로 채워지게 되는점 참고하세요...
void FlashErase(  )            // FLASH ERASE : 0xFF
{
    uint32_t PageError;

    __IO uint32_t data32 = 0 , MemoryProgramStatus = 0;    
    
    HAL_FLASH_Unlock();
    
    EraseInitStruct.TypeErase = FLASH_TYPEERASE_PAGES;      // TYPEERASE_PAGES;
    EraseInitStruct.PageAddress = FLASH_USER_START_ADDR; // PAGE ADDRESS
    EraseInitStruct.NbPages = 1;  // NbOfPages;   지울 페이지 갯수

// HAL_StatusTypeDef  HAL_FLASHEx_Erase(FLASH_EraseInitTypeDef *pEraseInit, uint32_t *PageError);
    if (HAL_FLASHEx_Erase(&EraseInitStruct, &PageError) != HAL_OK)
    { 
    Error_Handler();
    }
//    printf("Flash erase OK -> Sector%d\r\n",page);
    HAL_FLASH_Lock(); 
    
}

// 데이타 엎어 쓸때는 0x000000 으로 가능. 
void FlashSave(uint32_t Add,uint32_t data) 
{
    
  /* Unlock the Flash to enable the flash control register access *************/ 
  HAL_FLASH_Unlock();

   if (HAL_FLASH_Program(FLASH_PROC_MASSERASE, Add, data) == HAL_OK)  // 4byte씩 저장할때, 주소도 4씩 증감
// if (HAL_FLASH_Program(FLASH_PROC_PAGEERASE, Add, data) == HAL_OK)   // 2byte씩 저장할때, 주소도 2씩 증감
    {
//        printf("Flash write 0x%04X -> 0x%04X\r\n",Add,data);
    }
    else
    { 
      Error_Handler();
    }    
  HAL_FLASH_Lock(); 

}

==================================

실제 사용할때는 위에 있는 함수들만 호출하면됩니다.

읽는 동작이 빠졌군요... 읽기는 함수를 불러올 필요없이 프로그램 메모리를 직접 읽으면 되기에

아래와 같이 아주 간단히 처리됩니다.

USER_DATA = *(__IO char*)(USER_ADDR1);
    1byte = *(__IO char*)(CONFIGBASEADD+CONFIGVOLOFFSET);
    2byte = *(__IO uint16_t*)(CONFIGBASEADD+CONFIGVOLOFFSET);
    4byte = *(__IO uint32_t*)(CONFIGBASEADD+CONFIGVOLOFFSET);

 

디버그할때는 디버깅 상태에서 View -> Memory 를 선택해서 창을 연다음...

아래와 같이 시작 주소를 넣어주면 됩니다.

그림이 안보이면 클릭해보세요

끝.
