stm32 freertos hardfault - snprintf/vsnprintf/sprintf

Question

현재 하드 코어의 이유를 찾는 데 어려움이 있습니다. 정적 메모리 할당과 함께 freertos를 사용하고 있습니다. (malloc은 사용하지 않았습니다.) 미리 할당 된 버퍼 (새로운 (& 버퍼))를 사용하여 새로 사용합니다 .모든 스레드가 정렬되었는지 확인했습니다. (4) form of printf, 내 응용 프로그램은 freertos 호출에서 hardfault로 점프합니다. "첫 번째 작업 시작"

기본적으로 C89는 네임 스페이스와 클래스로 작성되므로 C++에 포함 된 것 이외의 다른 것은 없습니다. 각각의 C 파일 (.h)이 extern "C"로 묶여 있으므로 결코 연결 문제가 없습니다.

newlib, newlib nano 및 spare time 라이브러리의 tinyprintf로 테스트했습니다. 차이점이 없습니다.

또한, 나는 malloc을 호출에 결코 어설 션 실패, 그래서 내가 "매우"물론 더 newlib에 기능이 malloc에 ​​액세스하지 (I 바로 여기입니까?)

인터넷은 동적 메모리 할당 문제 중 하나를 제안한다 또는 스택 문제. hardfault의 원인을 어떻게 증명할 수 있습니까? 내 printf 호출로 인해 스택이 손상된다는 힌트는 잘못이 아니라고 생각합니다. 내가 어떻게 증명할 수 있니? (나는 스택을 디버깅 한 적이 없으며 스택 포인터를 디버깅하는 데 도움이 필요하다.)

다른 아이디어?

은 대단히 감사합니다

예 :

(void) vsnprintf(_log_buffer, C_LOG_BUFFER_SIZE, format, args); // hardfault 
(void) sprintf(_log_buffer, "huhu"); // no hardfault 

동적 할당 덮어 쓰기 :

__ATL_LINK_EXTERN_C void *malloc(size_t size) 
{ 
    (void) size; 

    atl::os::assert::failed((char*)__FILE__,__LINE__); 
    return NULL; 
} 

__ATL_LINK_EXTERN_C void * calloc(size_t size1, size_t size2) 
{ 
    (void) size1; 
    (void) size2; 

    atl::os::assert::failed((char*)__FILE__,__LINE__); 
    return NULL; 
} 

__ATL_LINK_EXTERN_C void *realloc(void * ptr, size_t size) 
{ 
    (void) ptr; 
    (void) size; 

    atl::os::assert::failed((char*)__FILE__,__LINE__); 
    return NULL; 
} 

__ATL_LINK_EXTERN_C void free(void * ptr) 
{ 
    (void) ptr; 

    atl::os::assert::failed((char*)__FILE__,__LINE__); 
}

그리고 디버거 무엇을 말하는가? 실제 HF가 무엇인지, 어디에서 발생했는지 확인 했습니까? 가능한 모든 HF에 대해 하나의 처리기가 있습니까? 그것은 디버깅을 훨씬 더 복잡하게 만듭니다. 그리고 적절한 명령어를 쓰십시오. "HF가 발생할 때 스택에서 레지스터 값을 저장하는 법"(http://www.freertos.org/Debugging-Hard-Faults-On-Cortex-M-Microcontrollers.html). 모든 일을 마쳤 으면 적절한 방법으로 조사를 시작할 수 있습니다.

불행히도 HF-s는 "게으른 방법"을 진단하기가 어렵습니다. 일부 코드 작성은 절대적으로 필요합니다.
