摘　　要：通过IAP(在应用中编程)升级APP(用户应用程序)是用户端进行程序升级的重要方法之一,从实际应用层面出发,主要解决了STM32中通过IAP升级APP程序的两个关键问题。首先是当APP程序的大小超过STM32的RAM空间时的处理方式;其次是在写入APP过程中不能从Flash取指令的解决办法。Upgrading APP(user application program)through IAP(programming in application)is one of the important methods for the client to upgrade the program.From the practical application level,this paper mainly solves two key problems of upgrading app through IAP in STM32.The first is the processing method when the size of APP program exceeds the RAM space of STM32.The second is the solution that the instructions cannot be taken from flash during the process of writing APP.
