摘要
针对基于ARM芯片的微控制系统,提出了一种利用在应用编程功能进行软件更新的方法,该方法利用SRAM执行读写闪存的程序,从而可以在同一块闪存上完成软件升级,并论证了方案的可行性。
This paper proposes a simple method based on ARM chip to update program of a Micro Control Unit (MCU) system by using In Application Program (IAP) function. The method uses SRAM to execute program to read and write the flash, thus updating program in the same flash. Its validation and efficiency are proved in this paper.
