TI中文支持网使用c6678开发平台；
Blackhawk XDS560v2-USB Mezzanine Emulator仿真器；
CCS: 5.2.1.00018；
仿真器相关配置如下：
测试连接的时候打印错误日志如下，麻烦帮忙分析一下，好多谢！

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the Nano-TBC VHDL.
The link is a 560-class second-generation-560 cable.
The software is configured for Nano-TBC VHDL features.
The controller will be software reset via its registers.
The controller has a logic ONE on its EMU[0] input pin.
The controller has a logic ONE on its EMU[1] input pin.
The controller will use falling-edge timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '2' (0x0002).
The utility logic has not previously detected a power-loss.
The utility logic is not currently detecting a power-loss.

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.

这块EVM板之前能连上仿真器么，还是一直连不上，截个图上来看看你是怎么连的，注意在上电后过个几分钟等等仿真器启动后再连接仿真器。

Andy Yin1，您好：
之前是一直用可以连接仿真器的，连接方法是用BiosMulticoreSDK_2.1_GettingStartedGuide.pdf讲述的方法：
而上述打印信息是我点击Test Configuration 测试连接的打印信息：
在Test Configuration测试连接的时候还有可能打印消息如下：

This error is generated by TI's USCIF driver or utilities.
The value is '-230' (0xffffff1a).The title is 'SC_ERR_PATH_MEASURE'.
The explanation is:The measured lengths of the JTAG IR and DR scan-paths are invalid.This indicates that an error exists in the link-delay or scan-path.

我们也遇到了同样问题，DSP上电后，检测checkout时钟是否正确，正确的话，内核应该工作正常，JTAG口烧坏
更换新的DSP，jtag做保护，连接正常

请教一下，用的板子是C6678，但是和pc了解是总是没反应，应该是驱动没有安装成功。请问驱动是否可以单独安装？
user6065283：
请问这个问题怎么解决呀
