你好 我用MSP432P401R 开发项目，昨天还是能下载连接成功，
今天就不能连接了，前期我用的是MSP-EXP432P401R 开发板写程序的
具体见word 附件非常急 MSP432开发板连接不上CCS.docx
Susan Yang 你好
1、按你提供的方法 进行测试，发现不行，本来就不能连接，想通过CCS 来进行对对芯片执行恢复出厂设置MSP432_Factory_Reset,......发现是不行的。
CS_DAP_0: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.4.0.00006) No connection possible. This could be caused by the device having gone to low power mode and disabling JTAG PINs. You have the option to either toggle reset or try to use SWD instead.
MSP432_Factory_Reset() cannot be evaluated.
Could not write register DP_RESET: target is not connected

2、最新版本和你给的文档 说法不一样。
这里 我选的是2PIN ，在上个文档里已说了
3、我用的就是从网上买的demo板 ，并且原来都能工作的。不用怀疑芯片型号
4、帮忙找个专家会诊一下，TI的开发 就是各种坑 ，希望你们能给个有限的方法。急急
