在此之前，板子是正常的，在此之后就出问题了：
1. 我在学习关于UART的例程，我将UART接口 DIO2 与DIO3 连接了一个另外一块CC2652 Launchpad后，我无法通过CCS debug烧录程序了,但我仍然可以使用uniflash烧写程序
2.错误代码如下：
Cortex_M4_0: Failed Board Reset: (Error -261 @ 0x0) Invalid response was received from the XDS110. (Emulation package 9.2.0.00002)
Cortex_M4_0: GEL: Error while executing StartUp( 10, 1, 0, 2013 ): Reset failed: retcode=-1
at GEL_AdvancedReset("Board Reset") [cc26x2.gel:29]
at StartUp(10, 1, 0, 2013)
IcePick_C: Error connecting to the target: (Error -261 @ 0x0) Invalid response was received from the XDS110. (Emulation package 9.2.0.00002)
3. 我该怎么办？
