在ST上正常的IAP程序到了APM上发现IAP以后FLASH内的数据不对，经过排查发现是写FLASH之前擦除FLASH没有成功。但是还有个疑问，根据资料介绍APM擦除速度要比ST的快，但为什么还需要加大等待时间。
- /* Delay definition */
- #define EraseTimeout ((uint32_t)0x000B0000)
- /* Delay definition */
- #define EraseTimeout ((uint32_t)0x001B0000)//加大EraseTimeout
- /* Wait for last operation to be completed */
- status = FLASH_WaitForLastOperation(EraseTimeout);
- FLASH_Status FLASH_WaitForLastOperation(uint32_t Timeout)
- {
- FLASH_Status status = FLASH_COMPLETE;
-
- /* Check for the Flash Status */
- status = FLASH_GetBank1Status();
- /* Wait for a Flash operation to complete or a TIMEOUT to occur */
- while((status == FLASH_BUSY) && (Timeout != 0x00))
- {
- status = FLASH_GetBank1Status();
- Timeout--;
- }
- if(Timeout == 0x00 )
- {
- status = FLASH_TIMEOUT;
- }
- /* Return the operation status */
- return status;
- }
