| 摘 要： | 许多ARM7芯片都包含了IAP功能,在程序运行过程中可以对Flash区编程,利用这一功能可以采用自定协议灵活地对ARM7芯片现场程序升级。文中以Philips公司的LPC2132为例介绍了更新程序的流程以及注意事项。该技术经过修改也可以用于其它具有IAP功能的芯片。

| Abstract: | Many chips of ARM7 include the function of IAP,through which we can program the flash memory of the chips.Field program updating can be achieved flexibly by using self-defined protocol based on this function.The flow and key point to realize program updating are introduced in this paper,taking LPC2132 of PHILIPS as an example.Slightly modified,this technology can also used in other chips with IAP function. |
