程式碼示例：

/*軟體復位*/

void G_mcuReset(void)

{

printf("\r\n\r\n\r\n%s\r\n\r\n\r\n",__FUNCTION__);

__set_FAULTMASK(1);

HAL_NVIC_SystemReset();

}

其實HAL_NVIC_SystemReset是

void HAL_NVIC_SystemReset(void)

{

NVIC_SystemReset();

}

其實NVIC_SystemReset是

__STATIC_INLINE void NVIC_SystemReset(void)

{

__DSB(); /* Ensure all outstanding memory accesses included

buffered write are completed before reset */

SCB->AIRCR = (uint32_t)((0x5FAUL << SCB_AIRCR_VECTKEY_Pos) |

(SCB->AIRCR & SCB_AIRCR_PRIGROUP_Msk) |

SCB_AIRCR_SYSRESETREQ_Msk ); /* Keep priority group unchanged */

__DSB(); /* Ensure completion of memory access */

for(;;) /* wait until reset */

{

__NOP();

__STATIC_INLINE void NVIC_CoreReset(void)

{

__DSB(); /* Ensure all outstanding memory accesses included

buffered write are completed before reset */

SCB->AIRCR = (uint32_t)((0x5FAUL << SCB_AIRCR_VECTKEY_Pos) |

(SCB->AIRCR & SCB_AIRCR_PRIGROUP_Msk) |

SCB_AIRCR_VECTRESET_Msk ); /* Keep priority group unchanged */

__DSB(); /* Ensure completion of memory access */

for(;;) /* wait until reset */

{

__NOP();

}

}

其實NVIC_CoreReset和NVIC_SystemReset基本一樣 我換了一個SCB_AIRCR_VECTRESET_Msk

測試：

void G_CoreReset(void)

{

printf("\r\n\r\n\r\n%s\r\n\r\n\r\n",__FUNCTION__);

__set_FAULTMASK(1);

HAL_NVIC_CoreReset();

}

void HAL_NVIC_CoreReset(void)

{

NVIC_CoreReset();

}
