TI中文支持网我现在用XDS100 V3烧录AM5728，使用CCS6.2.0进行test connection总是连接不上，
出现下面的错误信息，JTAG接口图在附件里。
哪位高手知道原因还请指点一下，谢谢！

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioserdesusbv3.dll'.
The library build date was 'Jan 24 2017'.
The library build time was '15:19:34'.
The library package version is '6.0.504.4'.
The library component version is '35.35.0.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '4' (0x00000004).
The controller has an insertion length of '0' (0x00000000).
This utility will attempt to reset the controller.
This utility has successfully reset the controller.

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the FTDI FT2232 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for FTDI FT2232 features.
The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).
An error occurred while hard opening the controller.

This error is generated by TI's USCIF driver or utilities.
The value is '-233' (0xffffff17).
The title is 'SC_ERR_PATH_BROKEN'.
The explanation is:
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.

Jian Zhou：
首先你的仿真器有在别的板子上验证过是好的么？
Denny%20Yang99373：
交叉实验，定位一下是仿真器的问题还是板子的问题或者是CCS软件配置的问题？

回复 Denny%20Yang99373:
多谢两位！我是新买的仿真器直接用的，还没测试过仿真器，我下一步马上验证。
我另外主要是担心JTAG接口，请问一下AM5728用附件这样的JTAG接口可以吗？
会不会有问题？谢谢！

回复 Denny%20Yang99373:
Denny，我再请教一下，CCS配置在连接选项里我是使用默认的配置，需要修改吗？谢谢！
