CCS5.3 使用 blackhawk 560V2 usb system TRACE 连接开发板，可以TestConnect ，但是debug时出现错误：
Error Connecting totarget(Error -234 @0x0)
the instruction scan-path cannot circulate bits.it may be broken . An attempt to scan the JTAG instruction registers has failed. The target's JT
AG instruction path appears to be broken with a stuck-at-ones or stuck-at-zero fault(Emulation package 5.0.872.0)
我查了一些资料 有人说可能是JTAG的TCLK的信号完整性问题 导致JTAG有问题 ，但是将TCLK从10M降到500K还是错误依旧，头大啊，望高手指教。
