_void FLASH_Erase_Sector(uint32_t Sector, uint8_t VoltageRange)
{
  uint32_t tmp_psize = 0;

  assert_param(IS_FLASH_SECTOR(Sector));
  assert_param(IS_VOLTAGERANGE(VoltageRange));

省略
...............
  __DSB();

运行到__DSB()指令后，jlink调试会停止run，报错如下：

_**JLink Warning: CPU could not be halted
***JLink Error: Can not read register 15 (R15) while CPU is running
***JLink Error: Can not read register 16 (XPSR) while CPU is running
***JLink Error: Can not read register 0 (R0) while CPU is running

***JLink E_rror: Can not read register 64 (FPS31) while CPU is running__**

但是如果点击几下run后，调试恢复正常，代码开始全速run。
有没有人用stm32f7+hal操作内部flash遇到这样的问题，求分享
