在选择Texas Instruments XDS110 USB Debug probe/C674X_0, 进行 Connect Target，就报错
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.5.0.00143)说我无法访问设备寄存器
我点测试连接时，
[Start: Texas Instruments XDS110 USB Debug Probe_0]
Execute the command:
%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioxds110.dll'.
The library build date was 'Oct 8 2021'.
The library build time was '13:26:36'.
The library package version is '9.5.0.00143'.
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.

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.
不是很懂问题出在哪
? ?：
这我板子图
,
Nancy Wang：
请问有参考过 Using CCS Debug for Development 吗？建议将详细的操作步骤描述一下。
dev.ti.com/…/node
,
? ?：
我就是按照这个参考一步一步来的，建立完新目标配置文件后，我点了Test CTest Connection 然后就跳出问题，然后我忽视这个问题选择C674X_0, 点击Connect Target就报错，说无法访问寄存器
,
Nancy Wang：
ccs debug firmware烧写了？sop是function mode吗？
,
? ?：
debug完连接仿真器出错，sop是101
,
Nancy Wang：
SOP模式不对。

? ?：
您好，我按照上面说明修改了还是一样问题
,
Nancy Wang：
你用的是iwr6843isk+mmwaveicboost吧，按照以下链接：
mmwave_industrial_toolbox_4_7_0__win/mmwave_industrial_toolbox_4_7_0/labs/common/docs/hardware_setup/hw_setup_mmwaveicboost_mode_functional.html

? ?：
问题依旧Error connecting to the target:(Error -2131 @ 0x0)Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).(Emulation package 9.5.0.00143)
,
Nancy Wang：
是第一次连接吗？稍后我试一下。
,
Nancy Wang：
我试了一下没有复现出问题，请详细说一下步骤，我可以帮助检查一下。
另外电源使用的是5V，>2A的吗？
,
? ?：
我用的是台式机机箱端口供电，不知道有没有5v3a
,
Nancy Wang：
mmwaveicboost的供电是要达到这个标准的。
,
? ?：
我用5v3a电源，问题依旧存在，我是按照操作说明一步步走的
,
? ?：
我在论坛上搜索https://e2echina.ti.com/support/archived-forums/f/other-analog-forum/197624/iwr6843isk-load-image-using-uniflash-not-able-to-connect-to-serial-port/614383发现这个帖子问题和我完全一样，是不是我也要换一个板子，我MMWAVEICBOOST版本也是b板
我是不是需要换一个板子，换a板吗
,
Nancy Wang：
我手上的也是B版本。
是否是先将ccs firmware单独烧写到ISK，然后再接上MMWAVEICBOOST debug。
,
? ?：
单独烧写没有找到合适端口啊，另外我用UNiflash可以在isk上单独烧写程序，如果加上BOOST后就是报错
问题汇总.docx这是我所有问题汇总，真的很急项目因为这个耽误太久了，一直没进展
,
Nancy Wang：
我看了一下你的 配合MMWAVEICBOOST烧写 部分，没有看出来有问题，因为你之前成功烧写过，建议重新换一块板子再测试排查一下。
,
? ?：
我需要换一块boost板子吗
,
Nancy Wang：
可以换一块再测试看一下。
