TI中文支持网hi，everyone！
我的板子之前做过从nand flash boot设置，现在想恢复出厂设置，遇到一些问题，请教高手。
软件版本：CCS5.2.1.00018_win32 和mcsdk_2_01_01_04（之前安装过bios_mcsdk_02_00_00_beta2_setup.exe，后来卸载了）
按照program_evm_userguide.pdf，选择no boot，设置$DSS_SCRIPT_DIR环境变量
执行脚本%DSS_SCRIPT_DIR%\dss.bat program_evm.js tmdxevm6678le -le
显示如下：
C:\Program Files\Texas Instruments\mcsdk_2_01_01_04\tools\program_evm>%DSS_SCRIP
T_DIR%\dss.bat program_evm.js tmdxevm6678le -le

shilong cao：
大侠，请问这个设置环境变量需要在CCS里面设置，还是在CMD中设置啊？那个program.js文件也是在CMD中运行么？
shilong cao：
我的也遇到了和你一样的问题！之前我烧写EEPROM时，不小心把里面的程序都擦除了，啥也做不了，所以才想恢复到初始状态。你现在的问题怎么样了？有什么好办法么？求指导！

回复 shilong cao:
回复有两种方法：
1. 就是使用上述的方法，建议可以下载最新的mcsdk试试看，
2. 另外就是参考mcsdk下的bootloader tools重新下载IBL及POST等程序到flash中。

我在安装随6678EVM附送光盘中的CCS5.2.1时，双击ti_emupack_setup5.0.838.0.exe时，提示我“bad central file record ”,请问是我的安装路径出了问题还是其他？
