NXP KL03--7.相同程序JLINK运行与FLASH直接运行，结果不一致

KL03 1个问题

1.相同程序JLINK运行与FLASH直接运行，结果不一致，程序是在vlps低功耗模式与正常工作模式之间切换

解决方法： 进入 VLPS低功耗语句 使用 __wfi(); 替换。

进入 VLPS低功耗语句使用 __wfi();  替换。 UART乱码问题没有，RF数据丢失暂时没有发现，这个替换，实际上并未进入低功耗吧？

 

void enter_vlps(void)

{

  #if 0

  volatile unsigned int dummyread;

  /* The PMPROT register may have already been written by init code

     If so then this next write is not done since 

     PMPROT is write once after RESET

     allows the MCU to enter the VLPR, VLPW, and VLPS modes.

     If AVLP is already writen to 0

     Stop is entered instead of VLPS*/

  SMC->PMPROT = SMC_PMPROT_AVLP_MASK;          

  /* Set the STOPM field to 0b010 for VLPS mode */

  SMC->PMCTRL &= ~SMC_PMCTRL_STOPM_MASK;

  SMC->PMCTRL |=  SMC_PMCTRL_STOPM(0x2);

  /*wait for write to complete to SMC before stopping core */ 

  dummyread = SMC->PMCTRL;

  /* Now execute the stop instruction to go into VLPS */

 

  /* Set the SLEEPDEEP bit to enable deep sleep mode (STOP) */

  SCB->SCR |= SCB_SCR_SLEEPDEEP_MASK;

  #endif

  __wfi();

 

}
