器件型号： XDS110ISO-EVM
您好、
我购买了一个 XDS110ISO-EVM 探针、因为非隔离式探针在调试期间由于共模噪声而不断断开连接。 但是、我无法让它正常工作。
我将在定制电路板上使用 F280033 目标。 使用常规非隔离式 XDS110 探针可以很好地对目标进行编程。
但是,当使用 XDS110ISO-EVM 探头（完全相同的工程,完全相同的 ccxml 文件）时,我会收到以下错误消息:
这是奇怪的,因为探头是正确地被 Windows 检测:
当我进入高级模式并尝试测试连接时,我会得到以下结果:

-----[Print the reset-command software log-file]-----------------------------
This utility has selected a 100/110/510 class product.
This utility will load the adapter 'jioxds110.dll'.
The library build date was 'Nov 20 2025'.
The library build time was '14:44:07'.
The library package version is '20.4.0.3756'.
The library component version is '35.35.0.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '5' (0x00000005).
The controller has an insertion length of '0' (0x00000000).
This utility will attempt to reset the controller.
This utility has successfully reset the controller.
-----[Print the reset-command hardware log-file]-----------------------------
The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the XDS110 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for XDS110 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 has occurred and this utility has aborted]--------------------
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.同样、常规 XDS110 探针没有问题。
请帮助我使其正常运行。
提前感谢、
Adrien
