LAUNCHXL-CC26X2R1: FLASH刷写错误导致设备被锁

LAUNCHXL-CC26X2R1: 使用UniFlash工具刷写bin，导致设备被锁，希望可以提供有效的解锁方法

使用tiarmobjcopy将 simple_peripheral_CC26X2R1_LAUNCHXL_tirtos7_ticlang.hex 转化为bin(352KB)文件，并使用unflash指定起始位置为0x30000烧录，结果设备被锁，无法继续刷写flash。

使用UniFlash全部擦书flash也无法恢复正常

windows设备管理器依然能够识别XDS110 com口

使用 异常开发板的XDS连接 正常的开发板的cc2642r1芯片可以进行flash刷写，因此怀疑是CC2642r1芯片被锁

错误log如下：
