尊敬的先生：

请找到随附的错误副本。

连接到目标时出错：
(错误-2131 @ 0x0)
无法访问器件寄存器。重置设备、然后重试此操作。如果错误仍然存在、请确认配置、对电路板进行下电上电、并/或尝试更可靠的 JTAG 设置(例如、降低 TCLK)。
(仿真包9.13.0.00201)

This utility has selected a 100/110/510 class product.
This utility will load the adapter 'jioxds110.dll'.
The library build date was 'Sep  6 2023'.
The library build time was '09:57:39'.
The library package version is '9.13.0.00201'.
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.
