stm32f405, FLASH读写, ic, ICE, vi

使用正点原子的Flash库

现在读写数值永远都不变，麻烦大家帮忙看看是什么情况？

[mw_shl_code=c,true]while (1) {

         static u8 id = 1;
         static u8 cha = 1;

         device_info.Device_id = id++;
         device_info.channel = cha++;

         STMFLASH_Write(FLASH_SAVE_ADDR, (u32*)&device_info, SIZE);

         delay_ms(500);

         //memset(&device_info, '\0', sizeof(struct_device_info));
         device_info.Device_id = 0;
         device_info.channel= 0;
         STMFLASH_Read(FLASH_SAVE_ADDR,(u32*)&device_info, sizeof(struct_device_info));

         print(&quot;ID = %d\r\n&quot;, device_info.Device_id);
         printf(&quot;Channle = %d\r\n&quot;, device_info.channel);
         delay_ms(500);

      }[/mw_shl_code]

FLASH_SAVE_ADDR这个改成什么都没用，读出来的数值要么就是255，要么就是一个常数，永远都不变
