一种基于SD卡的NorFlash烧写系统和方法
摘要：
本发明提供一种基于SD卡的NorFlash烧写系统和方法，包括：包括相互通信的处理器模块、NorFlash芯片和SD存储卡，NorFlash芯片通过LocalBus总线与处理器模块连接；其中，处理器模块，用于外挂NorFlash芯片和SD存储卡，采用跳线方式选择启动方式；NorFlash芯片，用于存储BootLoader引导程序，并作为处理器模块常规启动介质；SD存储卡，用于当处理器模块选择通过SD存储卡启动时，将BootLoader引导程序烧写并存储至NorFlash芯片中。该系统及方法为嵌入式系统开发NorFlash烧写提供一种低成本、简单可靠的技术手段。
摘要（英）：

The present invention provides an SD card based NorFlash programming system and method. The system comprises a processor module, a NorFlash chip and an SD storage card that are communicated with one another. The NorFlash chip is connected with the processor module through a Local Bus. The processor module is used for externally hanging the NorFlash chip and the SD storage card, and selecting a startup mode by means of a jumper manner. The NorFlash chip is used for storing a BootLoader guide program, and is used as a normal startup medium of the processor module. The SD storage card is used for programming and storing the BootLoader guide program in the NorFlash chip when the processor module chooses to start up by means of the SD storage card. The system and method provide a low-cost, simple and reliable technical means for development of NorFlash programming of an embedded system.
