bypass板载XDS110,通过外部的XDS110仿真器连接AWR1642BOOST时出错的问题

你好,我在用AWR1642BOOST进行开发,想尝试bypass板载XDS110,通过外部的XDS110仿真器进行在线调试,

具体操作如下:

去掉了电阻R176,以断开板载XDS110的供电,从60pin HD connector 附近飞了5根线(TDI、TDO、TCK、TMS、GND),连到XDS110的CTI-20的对应引脚上,

并将SOP[2:0]设置为001。

然后,在CCS端,进行Target Configurations,选择“Texas Instruments XDS110 USB Debug Probe”,以及“AWR1642”。

生成ccxml文件,进行Test connection,出现如下错误:

An error occurred while hard opening the controller.

—–[An error has occurred and this utility has aborted]——————–

This error is generated by TI's USCIF driver or utilities.

The value is '-267' (0xfffffef5).
The title is 'SC_ERR_XDS110_TARGET_SUPPLY'.

The explanation is:
The controller could not detect valid target supply. Check target
JTAG connection and/or connection setting specifying voltage level.

[End: Texas Instruments XDS110 USB Debug Probe_0]

请问:
(1)上述情况是怎么回事?我哪里设置的不对吗?
(2)JTAG相关的5根线长度有限制吗,是否不能太长?
(3)JTAG相关的飞线是这5根吗?还需要电源?TRST吗?

你好,我按上述连接后,仍然有问题,如下:
—–[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.

[End: Texas Instruments XDS110 USB Debug Probe_0]

请问,接下来我还需要怎么做?

回复 Wesley He:

另外,我是讲上述信号从AWR1642BOOST的开发板飞线连到了XDS110仿真器的CTI-20的接口上。

回复 Wesley He:

你好,问题已经解决了。多谢。

回复 user5832592:

你好,请问这是什么原因?是不是后来的推荐的原理 图13、14 管脚没有上拉?

回复 user5832592:

你好!我现在遇到同样的问题,采用外部XDS110无法下载,报错,无法下载;请问你是怎么解决的?
