用CCS连接XDS100V3调试目标板的一例故障解决 [复制链接]

最近用CCS连接XDS100V3调试CC1310时，发现无法连接目标板。

在Verify时报错如下：

[Start]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

[Result]

-----[Print the board config pathname(s)]------------------------------------

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

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioserdesusbv3.dll'.
The library build date was 'Nov  6 2017'.
The library build time was '10:36:36'.
The library package version is '7.0.100.0'.
The library component version is '35.35.0.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '4' (0x00000004).
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 FTDI FT2232 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for FTDI FT2232 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 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 '-275' (0xfffffeed).
The title is 'SC_ERR_SCAN_POLL_BUSY'.

The explanation is:
The attempt to poll a target device exceeded its timeout limit.
The utility or debugger has requested that a target device be
repeatedly accessed for a specific data or status value.
This has failed because the built-in limit for the maximum number
of attempts when polling the JTAG scan-path has been exceeded.

[End]
 

经检查是由于电池供电的CC1310电压低（小于1.5V）造成。更换后恢复正常电压，能够正常调试
