28335的板子仿真器和JTAK连接不上去,报这个错误Error -233

Error connecting to the target:
(Error -233 @ 0x0)
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.

Seven Han:请问设备管理器可以找到仿真器吗?
是否有尝试更换个usb再连接。

您用哪个版本的ccs,还有仿真器型号呢?
建议您用高版本的ccs,自带仿真器驱动。先排除仿真器的问题,板子供电,正确设置仿真器配置,然后重新连接。
