参考https://github.com/rafaellcoellho/bsl-msp430来进行MSP430F5529开发板的固件升级，在进行到Testing步骤时，结果如下图
1、MSAA_ERASE,PC端下发80 01 00 15 64 A3指令给MSP430开发板，开发板其实是收到了，校验checksum通过并回了ACK(上图的<00>)。接下来跑到BSL430_massErase（）函数时，程序就异常了。
2、RX_PASSWORD，PC端下发80 21 00 11 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF 9E E6，开发板也是收到了，并回了checksum OK的ACK(上图的<00>)。接下来跑到BSL430_unlock_BSL()函数，校验密码不对，再跑到BSL430_massErase（）时，程序又异常了。
感觉哪里的配置没配置对，导致密码校验和擦除出问题。CCS我用的6.1.0版本，
Ben Qin：
你好，我需要时间查看下代码，我会尽快回复您。
,
Ben Qin：
你好，检查一下两边波特率是否相同。如果方便能够提供源代码？
jing zhang 说：接下来跑到BSL430_unlock_BSL()函数，校验密码不对
可以确认接受的密码是正确的吗？
,
jing zhang：
波特率是相同的，后面又增加了打印，把接收的数据打印出来，是32个FF的，接收的数据也是没错的。
,
jing zhang：
源码怎样提供呢？
,
Ben Qin：
可以将工程打包成压缩文件夹发送到论坛上，如果你不愿意公开，也可以通过好友私信发给我。
,
jing zhang：
这论坛在哪可以带压缩文件的，在插入——》文件，只能带文件类型的东西，压缩文件不让上传的。方便给个邮箱吗，我直接邮件你。
,
Ben Qin：
直接使用鼠标拖拽就可以了。

Ben Qin：
好的，我需要一些时间来查看代码，一旦有结果会立刻回复您。
,
Ben Qin：
你好，抱歉回复晚了。
你是如何将板子和电脑连接的？

Andrew Su：
FW_upgrade_5.zip
,
Andrew Su：
附件是工程包压缩文件，请帮忙看看
,
Ben Qin：
好的，我这边会尝试调试一下。
,
Ben Qin：
你好，试过用和文章https://github.com/rafaellcoellho/bsl-msp430作者一样版本的编译器吗？
,
Ben Qin：
你好，该程序是可以成功运行的：
你的配置没有问题。
调试过程中发现该程序只能使用一次，也就是说，只有第一次可以成功。每调试一次需要重新烧录BSL。
,
jing zhang：
比如编了3个版本分别是A,B,C。从A版升级到B版是OK，这时想再从B版升级到C版，就一直升级不了（失败了），这时该如何处理？
,
Ben Qin：
这个程序原作者设计的应该是只能使用一次，也就是说只能升级一次。
你需要根据自己的需要来修改程序。
