目前使用280049C LaunchPad kit

連接線是包裝內的 USB micro-B plug to USB-A plug cable

電腦環境為macOS

IDE環境為CCS Version: 8.3.1.00004

Target Configuration test connection:

The JTAG DR Integrity scan-test has succeeded.

進入DEBUG則出現以下錯誤訊息：

Error connecting to the target:

(Error -151 @ 0x0)

One of the FTDI driver functions used during the connect

returned bad status or an error. The cause may be one or

more of: no XDS100 is plugged in, invalid XDS100 serial number,

blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable.

Use the xds100serial command-line utility in the 'common/uscif'

folder to verify the XDS100 can be located.

(Emulation package 8.1.0.00012)

连接之前是否有按照用户手册上的说明对开发板进行设置？如果设置都没问题的话可以参考以下链接的解决方案：
software-dl.ti.com/.../ccsv7_debugging_jtag_connectivity_issues.html
另外，最好使用Windows操作系统和最新版CCS进行实验。

出错原因就是上述的链接介绍的几种都有可能，但根据错误信息的话不能判断具体是哪种。

請問你說的用戶手冊是SPRUII7A這一份文件嗎？

是的，里面有介绍几个跳帽的连接等等问题。

另外也可以试一下Bypass CLA选项

如上述說Target Configuration test connection是可以成功連接的，但是DEBUG無法過。

已測試如你所說bypass CLA 仍然無法進入debug

Whycan'tIconnecttotheLaunchPadinCodeComposerStudio?
a. AreshuntspresentonJ101forTCKandTMS?
b. IstheXDS110andtheF280049CMCUpowered?IsLED1illuminated?

If JP1, JP2, and JP3 are disconnected, the power provided through the USB is isolated from the rest of the board. Ensure that 3.3 V is supplied to any of the available connectors on the target side of the isolation.

c. Is the micro-USB connected to the PCB and is the USB region receiving power? Is LED0 illuminated?

The USB region must be powered with the 5 V from the USB cable. LED0 will illuminate when the 5V is stepped down to 3.3 V for the USB isolation chip to operate and pass the signals across the isolation barrier.

d. EnsurethatthetargetconfigurationissetuptousecJTAGin2-pinadvancedmode.

Open the Target Configuration file (.ccxml) in Code Composer Studio. Click on the Advanced tab and select cJTAG (1149.7) 2-pin advanced modes from the drop-down labeled JTAG/SWD/cJTAG Mode. Leave the Target Scan Format as OSCAN2 format.

Alternately, a working Target configuration file is included in the launcxl_ex1_f280049c_demo project "TMS320F280049C_LaunchPad.ccxml". You can use this without modifications.

您好，我目前遇到和你类似情况。
Target Configuration test connection是可以成功，但Debug就是出错，Error-2131@0x0，不知道什么原因呢

您可以先試試launchPad example 連接看看能不能過。

如果有任何歡迎與我聯繫！

您好，我就是用的LauncdPad的example，已经改成cJTAG 2-pin，Target Configuration test connection成功，然后在Project下删除了原有的Targetconfigs，自己重新新建就可以了
