你好！我用的仿真器是XDS100V3和TMS320f28335，之前可以连接，在一次烧写Flash卡死后，就不能连接了，报错：
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 5.1.507.0)
请问是芯片被锁死了吗？怎么确定？
