评估板特别适用于DSP开发的初学者但有时候拿到手的开发板几经流转被别人修改过也可能自己烧录过程出错导致开发板的状态未知等原因需要恢复到出厂默认状态本文主要介绍如何利用官方提供的工具将开发板恢复到出厂默认状态。

在开始前需要安装CCS工具默认安装完成后会在安装为准。

如果没有program_evm文件夹可以使用购买时厂家提供的光盘里的program_evm文件夹里程序。

操作步骤

2将评估板上自带的XDS200仿真器通过USB连接线与电脑相连确保J4

均处于开路状态

3将评估板上COM_SEL1跳线中的3-5针相连4-6针相连选择使用三针串口并用评估板自带的串口连接线连接至电脑的串口。

如果选择使用板上的USB-uart需要将COM_SEL1跳线中的1-3针相连2-4针相连

4将16个BOOT拨码开关调整到如下状态

由于program_evm\binaries\evm6657l文件夹中没有nand.bin镜像文件所以会提示nand
