摘要
Bootloader是微处理器上电时运行的第一段代码,它可以通过通信接口实现对微处理器内部应用程序的更新升级,为网络化嵌入式产品的应用程序升级带来极大的便利。由于目前没有统一嵌入式系统的Bootloader。基于NEC78K0系列单片机自编程原理,设计出一个适用于78K0/Fx2系列单片机的Bootloader,并能够通过单片机串口在线升级应用程序。
Bootloader is the first piece of code executed after microprocessor startup. It makes the embedded product＇s firmware update conveniently through communication interface. However, no unified bootloader is available for all kinds of microprocessor products. Based on the principle of self-programming NEC 78KOs＇ series, a useful Bootloader which is suitable for 78KO/Fx2s＇ series MCU is designed, the design can update the application through serial ports.
