Bootloader是微處理器上電時運行的第一段代碼，它可以通過通信接口實現對微處理器內部應用程序的更新升級，為網絡化嵌入式產品的應用程序升級帶來極大的便利。由于目前沒有統一嵌入式系統的Bootloader。基于NEC 78K0系列單片機自編程原理，設計出一個適用于78K0/Fx2系列單片機的Bootloader，并能夠通過單片機串口在線升級應用程序。
Abstract:
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 78K0s’ series， a useful Bootloader which is suitable for 78K0/Fx2s’ series MCU is designed，the design can update the application through serial ports.
