利用HEX文件实现TMS320F28335的程序升级方法

提出了一种通过发送HEX文件到TMS320F28335进行程序升级的新方法.配置TMS320F28335为FLASH启动模式,通过预烧写升级程序到FLASH中,可实现在串口发送HEX文件升级用户程序的功能.详细介绍了该方法实现原理和开发过程,并且给出软件流程图和关键代码.实验证明,该方法操作方便,可靠性高,大大提高了效率.

Software Updating Method of TMS320F28335 Using HEX File

In the paper,a new method of FLASH updating by transmitting HEX file to TMS320F28335 is proposed.To realize the function of updating the application program by sending HEX file to the TMS320F28335,it is configured as a FLASH boot mode and the program used for updating is downloaded into the FLASH.The implementation principle and the development process of this method are introduced,and the software flowchart and the critical code are given.The experiment results indicate that the new method is simple to operate and has high reliability,so this method improves the working efficiency.
