错误信息如下：
C28xx: 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. (Emulation package 5.1.450.0)

板子和仿真器都是新的，ccs版本是6.0.0。请各位帮忙看看是什么问题啊？希望不要是硬件问题。
