一种烧写TMS320LF240xA的新方法

A New Method for Writing TMS320LA240xA

介绍了TMS320LF240xA内部FALSH的特性和优点,标准JTAG接口各个主要引脚的定义,通过并口将PC与目标板上的边界扫描器件(标准JTAG接口)相连,烧写TMS320LF240xA内部FLASH的新方法。同时,文章论述了烧写TMS320LF240xA内部FLASH的闪存编程命令、烧写FLASH时的步骤和注意事项,给出了CMD文件中变量的定义,以及将const section加载进程序存储器的方法和示例程序。

First the features and virtues of TMS320LF240xA flash are introduced in the paper. Then the definition of JTAG main pins is introduced. At last the paper sets forth the new method of writing TMS320LF240xA flash by standard JTAG. That is, PC is connected with standard JTAG of the host controller on board with parallel port. The processes and cautions are introduced. The commands of TMS320LF240xA flash are also given. The way of allocating const section to program memory and exampled program is simply introduced.
