FreeRTOS-移植Cmbacktrace

1. 下載Cmbacktrace

Cmbacktrace的github目錄為：https://github.com/armink/CmBacktrace
下載到本地會得到如下目錄的文件

在demo/os/freertos下會有STM32F103的實例。我的型號是STM32L496

2. 在工程中添加對應的目錄

cmbacetrace.c在cm_backtrace下，cmb_fault在CmBacktrace-master\cm_backtrace\fault_handler\keil下
添加對應頭文件目錄的包含

3. 進行配置

main函數：

#include "cm_backtrace.h"
cm_backtrace_init("CmBacktrace", "V1.0.0", "V1.0.0");

cmb_cfg

/* print line, must config by user */
#define cmb_println(...)             printf(__VA_ARGS__);printf("\r\n"); /* e.g., printf(__VA_ARGS__);printf("\r\n") */
//#define cmb_println(...)  							BSP_UARTPrintf(DBUART, __VA_ARGS__);BSP_UARTPrintf(DBUART,"\r\n");
/* enable bare metal(no OS) platform */
/* #define CMB_USING_BARE_METAL_PLATFORM */
/* enable OS platform */
/* #define CMB_USING_OS_PLATFORM */
#define CMB_USING_OS_PLATFORM
/* OS platform type, must config when CMB_USING_OS_PLATFORM is enable */
/* #define CMB_OS_PLATFORM_TYPE           CMB_OS_PLATFORM_RTT or CMB_OS_PLATFORM_UCOSII or CMB_OS_PLATFORM_UCOSIII or CMB_OS_PLATFORM_FREERTOS */
#define CMB_OS_PLATFORM_TYPE           CMB_OS_PLATFORM_FREERTOS
/* cpu platform type, must config by user */
#define CMB_CPU_PLATFORM_TYPE          CMB_CPU_ARM_CORTEX_M4/* CMB_CPU_ARM_CORTEX_M0 or CMB_CPU_ARM_CORTEX_M3 or CMB_CPU_ARM_CORTEX_M4 or CMB_CPU_ARM_CORTEX_M7 */
/* enable dump stack information */
/* #define CMB_USING_DUMP_STACK_INFO */
#define CMB_USING_DUMP_STACK_INFO
/* language of print information */
/* #define CMB_PRINT_LANGUAGE             CMB_PRINT_LANGUAGE_ENGLISH(default) or CMB_PRINT_LANGUAGE_CHINESE */
#define CMB_PRINT_LANGUAGE	CMB_PRINT_LANGUAGE_ENGLISH
#endif /* _CMB_CFG_H_ */

task.c

添加如下函數

/*< Support For CmBacktrace >*/
uint32_t * vTaskStackAddr()
{
    return pxCurrentTCB->pxStack;
}

uint32_t vTaskStackSize()
{
    #if ( portSTACK_GROWTH > 0 )
    
    return (pxNewTCB->pxEndOfStack - pxNewTCB->pxStack + 1);
    
    #else /* ( portSTACK_GROWTH > 0 )*/
    
    return pxCurrentTCB->uxSizeOfStack;
    
    #endif /* ( portSTACK_GROWTH > 0 )*/
}

char * vTaskName()
{
    return pxCurrentTCB->pcTaskName;
}
/*-----------------------------------------------------------*/

這時候時候會顯示沒有pxCurrentTCB->uxSizeOfStack
typedef struct tskTaskControlBlock中添加

#if( portSTACK_GROWTH <= 0)
UBaseType_t     uxSizeOfStack;      /*< Support For CmBacktrace >*/
#endif

static void prvInitialiseNewTask中添加

pxNewTCB->uxSizeOfStack = ulStackDepth;   /*< Support For CmBacktrace >*/

FreeRTOS.h

typedef struct xSTATIC_TCB中添加

#if(portSTACK_GROWTH <= 0)
        UBaseType_t     uxSizeOfStack;      /*< Support For CmBacktrace >*/
#endif /* ( portSTACK_GROWTH > 0 )*/

4. 驗證

加上打印串口后可以使用人工制造一個除零錯誤等實驗一下。錯誤的實例在demo中可以找到
