Error connecting to the target

CC3200测试例程wlan_station时，昨天晚上测试时候都是没问题的。今天再试时，打开串口助手就会出现这个错误（Error connecting to the target）；关闭串口助手，仿真成功，亮灯现象也正常。

请问怎么解决这个问题？

Terry Han：

cc3200的SOP跳线帽有没有跳到SOP2为高电平？ 在100的模式下，CC3200启动后才能通过串口连接到PC软件串口助手；

这个错误（Error connecting to the target）——这个错误是你用Uniflash的软件连接CC3200提示的信息？

SOP设置

当将SOP2短路后才可以通过uniflash进行下载，下载完成后要拔掉SOP2否则程序一直等待状态！

特别注意Launchpad上的SOP选项中跳线帽短路2是选择CC3200从串口等待烧录Uniflash的数据，短路0是选择CC3200的调试方式为两线的SWD，拔掉跳线帽0,1,2全部悬空为四线的JATG模式；

16.8.6 Sense on PowerCC3200 implements a sense on power scheme. By using a few board level pull resistors CC3200 can be configured by the user to power up inone of the three following modes:

1. Fn4WJ: Functional Mode with 4-wire JTAG mapped to fixed pins2. Fn2WJ: Functional Mode with 2-wire SWD mapped to fixed pins3. LDfrUART : UART Load Mode for flashing the system during development and in OEM assembly line (eg: serial flash connected to CC3200R)Sense on Power (SoP) values are sensed from the device pin during power up. This encoding determines the boot flow as well as the defaultmapping for some of the pins (JTAG, SWD, UART0). Three SoP pins are used for this purpose. Before the device is taken out of reset, the SoPvalues are made available on a register and determine the device character while powering up. Table 16-13 shows the pull configurations.

我用的是ccs仿真时候的问题。SOP2跳线帽接着。
