我尝试了加密后觉得加密不是很好用，又想解密了，但是怎么都不成功。
一、在ccs--On-Chip Flash里面点击解密，然后擦除FLASH，重新烧写还是提示解密失败。
二、在ccs--On-Chip Flash里面点击解密，然后把密码都改成0xFFFFFFFF，点击Program Password，提示
我尝试了用uniFlash来解密，但还是一样的结果
请问，还有什么办法解密吗？

一、清除flash方式
1. 通过ram运行的模式调试blinky_led例程连接到28377，然后点击菜单栏Tools -- On Chip Flash
2. 在On Chip Flash标签页找到CSMPSWD组，输入密码，点击Unlock
3. 在On Chip Flash标签页中点击Erase Flash。
二、直接修改密码方式
1. 通过ram运行的模式调试blinky_led例程连接到28377，然后点击菜单栏Tools -- On Chip Flash
2. 点击工具栏复位芯片
3. 输入密码解锁，把密码换成0xFFFFFFFF，然后点击Program Passwod
这两种方式都尝试过了，然后烧写程序还是要密码才能烧写，但是烧写完，USB通信不正常，能连接，但是上位机发送的数据28377好像接收不了。
