摘要
本文针对存储器程序更新的问题,提出一种基于STM32的IAP程序更新方法 -通过STM32的FSMC接口实现NOR Flash访问,并以JFM-F512K32芯片为例,说明FSMC接口的配置方法,通过IAP程序运行实现Flash存储器数据的更新。该设计成功实现Flash程序的自动更新功能,操作简单、速度快、正确率高。
In order to solve the problem of memory software update, this paper proposed an IAP program update method that based on STM32-access the NOR Flash controller by the FSMC interface of STM32 processor.And the paper illustrated with an example of JFM-F512K32 chip, analyzing configuration way of FSMC interface, realized the function of data of flash memory by run IAP program.This design have successful realized the purpose of automatic update of flash program, easy to use, and also have rapid speed and high validity.
