连接不上目标板

CCS3.3开发环境，之前用的好好的，昨天突然连接不上，弹出如下报错：

Error connecting to the target:
Error 0x80000240/-233
Fatal Error during: Initialization, OCS,This error was generated by TI's USCIF driver.

SC_ERR_PATH_BROKEN <-233>
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.

retry后弹出如下报错：

Error connecting to the target:
Error 0x80000200/-1047
Fatal Error during: OCS,PTI_ERR_EMU_CLOSE Error Occured at 0x00000000

连接其他板卡都是正常，应该能排除仿真器的问题。是JTAG接口出问题了么？

PS：我记得TI好像有一篇解释报错信息的文档，能贴个链接么?

TI确实有一篇解释报错的文档，不过是解释编译报错的。

关于连接报错，楼主你参考一下下面的链接：

首先谢谢你的解答。

看了您给的链接，请问会是锁死么？加密锁死的话应该不会连仿真器都连接不上吧。而且我烧写的时候并没有加密啊。

PS：TICompiler_C28_ErrorList[1].pdf 这里边只有报错列表，请问有没有对报错信息有具体说明的文档呢？

“This error was generated by TI's USCIF driver.”

该问题一般为仿真器驱动不兼容，报错在升级CCS到最新版本并联系仿真器生产企业索要最新仿真器驱动后可以解决此问题。

具体的原因还是要做交叉实验确认。

没有更具体的说明文档。

连接其他板子都可以，就这一块板子连不上，应该跟仿真器或ccs版本没关系吧。而且这块之前也没问题，前天烧了一次程序后突然就不行了。

楼主使用的是哪颗芯片？

如果是加密的原因连不上仿真器的，可以尝试一下将单片机复位管脚拉低然后连接仿真器看是否能连上，如果能连上，说明可能芯片已经锁住，但密码不是全为0.

我的情况也是这样，其他板子都可以连接并烧录，这块却连接不上。

第一次连接

Error connecting to the target: Error 0x80000240/-233 Fatal Error during: Initialization, OCS, This error was generated by TI's USCIF driver. SC_ERR_PTH_BROKEN <-233> An attempt to scan the JTAG scan-path has failed. The target's JTAG scan-path appears to be broken with a stuck-at-ones or stuck-at-zero fault.

点connect后出现：Error connecting to the target: Error 0x80000200/-1037 Fatal Error during: OCS, PTI_ERR_EMU_CLOSE Error Occured at 0x00000000 Error connecting to the target: Error 0x80000200/-1037 Fatal Error during: OCS, PTI_ERR_EMU_CLOSE Error Occured at 0x00000000 Error connecting to the target: Error 0x80000200/-1037 Fatal Error during: OCS, PTI_ERR_EMU_CLOSE Error Occured at 0x00000000 Error connecting to the target: Error 0x80000200/-1037 Fatal Error during: OCS, PTI_ERR_EMU_CLOSE Error Occured at 0x00000000 Error connecting to the target: Error 0x80000200/-1037 Fatal Error during: OCS, PTI_ERR_EMU_CLOSE Error Occured at 0x00000000

请大家说说到底如何解决？谢谢

兄弟，我也是这种情况，你解决了么？可以告诉我怎么做么？不过我是第一次上电就连接不上，而且什么板子都连接不上，有些时候还会出现蓝屏，知道怎么解决么？谢谢
