用XDS100V3给CC1310下载程序时，发现如下连接错误：

An error occurred while hard opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-241' (0xffffff0f).
The title is 'SC_ERR_ROUTER_SECURE_SUBPATH'.

The explanation is:
A router subpath could not be accessed.
A security error has probably occurred.
Make sure your device is unlocked.

解决方法如下：

1.确定型号选择正确：

连接好XDS100V3的硬件接线后，按照上图中五个步骤依次进行配置选型并尝试连接，如果还是报错继续尝试以下步骤：

2.打开离线Flash编程工具：FLASH-PROGRAMMER-2（根据不同片子型号，选择FLASH-PROGRAMMER或FLASH-PROGRAMMER-2，V2主要适用于CC13x0/CC26x0/CC2538等M3内核），如果未安装该工具，可前往官网下载：FLASH-PROGRAMMER Software programming tool | TI.com；

3.点击左下角 Refresh，并选中CC1310，在弹出的提示框中点击OK；

4.点击设置（右上角扳手图标），选择擦除对象型号，提示框中点击ok

即可擦除成功：

5.重返CCS中，点击connect，即提示连接成功~
