摘要
伴随着信息与通讯技术产业的发展,嵌入式系统的产品和应用日益普及,在日常生活中扮演着重要的角色。德州仪器公司(TI)的F2812芯片在嵌入式系统的设计与实现中受到广泛的应用。传统方法是通过JTAG调试架构对芯片进行读写,存在着诸多不便。针对此问题,通过研究和实验,使用串行数据通信标准接口RS232对芯片进行数据读写,提出一种新的实现程序更新的方法。使用Intel公司提出的通用HEX文本格式对串口芯片进行数据读写,此种文本格式通用性强,适合在多种场合下使用。研究得出的方法可以广泛适用于其他嵌入式芯片,从而大大降低通过使用JTAG接口带来的不便。
With the development of information and communication technology industry, embeddedsystem products and applications are becoming more and more popular, playing an important role in dailylife. F2812 chip of TI is widely used in the design and implementation of embedded system. The tradi-tional method is to read and write the chip through JTAG debug architecture, which is very inconve-nience, in view of this problem, through research and experiment, using serial data communication stan-dard interface RS232 to read and write the chip data, a new method to achieve program update is pro-posed. The serial port chip is read and written with the universal hex text format proposed by Intel corpo-ration, and this text format is universal and suitable for many occasions. The method can be widely ap-plied to other embedded chips, thus greatly reducing the inconvenience caused by using JTAG interface.
