AM62A7: why cannot use XDS200 connect to AM62A7?

Part Number: AM62A7

Hi,

I use this debug setup , and click "Test Connection", but failed. The log is as follows:

[Start: Texas Instruments XDS2xx USB Debug Probe_0]

 

Execute the command:

 

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

 

[Result]

-----[Print the reset-command software log-file]-----------------------------

 

This utility has selected a 560/2xx-class product.
This utility will load the program 'xds2xxu.out'.
The library build date was 'Jun  2 2023'.
The library build time was '17:37:16'.
The library package version is '9.12.0.00150'.
The library component version is '35.35.0.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '13' (0x0000000d).
The controller has an insertion length of '0' (0x00000000).
This utility will attempt to reset the controller.
This utility has successfully reset the controller.

This emulator does not create a reset log-file.

 

-----[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.

Do you know the problem? By the way, how to slow down the speed of XDS200?

  • [Start: Texas Instruments XDS2xx USB Debug Probe_0]

    Execute the command:

    %ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

    [Result]

    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 '-180' (0xffffff4c).
    The title is 'SC_ERR_CTL_NO_TRG_POWER'.

    The explanation is:
    The controller has detected a target power loss.
    The user must turn-on or connect the power supply for the target.

  • 请问是TI的EVM板还是自己的板子?

  • 自己项目的。

  • 请问是自己的板子是参考EVM板吗?请按照下面的文档检查一下JTAG电路。
