STM32F4, iap, Bootloader, ADDR, DDR

这个是跳转函数
void loading_program(uint32_t LoadAddress)
{
if (((*(__IO uint32_t*)LoadAddress) & 0x2FFE0000 ) == 0x20000000)/*检查栈顶地址是否合法*/
{
            U2_Printf(&quot;
M2 Ready to go to the APP!
&quot;);
            osDelay(50);
            /*Debug*/
            U2_Printf(&quot;Jump Address:0x%08X
&quot;, ((*(uint32_t*)LoadAddress) & 0x2FFE0000 ));
            osDelay(100);

            Disable();

      JumpToAddress = (pFunction)*(uint32_t*) (LoadAddress + 4);
      MSR_MSP(*(__IO uint32_t*) LoadAddress);
      JumpToAddress();       /*跳转app*/
}
      else
      {
            U2_Printf(&quot;
M2 Loading APP ERROR!
&quot;);
            osDelay(50);
            U2_Printf(&quot;Load Address:0x%08X
&quot;, LoadAddress);
            osDelay(50);
            /*Debug*/
            U2_Printf(&quot;Jump Address:0x%08X
&quot;, ((*(__IO uint32_t*)LoadAddress)&0x2FFE0000));
            osDelay(1000);
      }
}

跳转打印是这个
M2 Loading APP ERROR!
Load Address:0x08020000
Jump Address:0x28160000

一直无解为什么是这样
