STM32软件复位

在需要复位的地方调用NVIC_SystemReset()函数。

core_cm3.h中对NVIC_SystemReset()函数定义如下

/**

\brief System Reset

\details Initiates a system reset request to reset the MCU.

*/

__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();

}

}
