Hi, I'm using an old revision of XDS100v3; this one doesn't have the "JUMPER ARM_JTAG_E".
So I'm trying to use the "TI's 20 pin JTAG connection" with my perf board that uses TM4C123GH6PMI.
I have created a JTAG connection like the above schematic.
However, while using the CCS 7, I have received an error.
Is the above connection invalid; do I have to add a pull-up resistor to pin 4?
Hello,
AartiG said:connection properties to be set in the CCS target configuration file?
you mean this?
I cannot find that "connection properties" on CCS 7.

</platform>
</connection>
</configuration>
</configurations>
This is my current configuration.
You mean I haven't followed the instruction fully, right?
Then how can I configure "nTRST boot-mod" or more with CCS 7?

Highlight the "Texas Instruments XDS100v3 USB Debug Probe" node in the left pane to see those properties.
Hi, thanks for your help, I have changed the configuration file like the picture below.
To be more specific, I use XDS100-v3 revision B.
However, the error 183 (SC_ERR_CTL_CBL_BREAK_FAR) was shown when I tried to debug or test the connection.
Start: Texas Instruments XDS100v3 USB Debug Probe_0]
Execute the command:
%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

The controller does not use a programmable FPGA.
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 '-183' (0xffffff49).
The title is 'SC_ERR_CTL_CBL_BREAK_FAR'.
The explanation is:
The controller has detected a cable break far-from itself.
The user must connect the cable/pod to the target.
[End: Texas Instruments XDS100v3 USB Debug Probe_0]
As you remember, my perf board connection is like this.
The VDDC pins (25 & 56) show 1.397 V on the multimeter.
Then is this related to wiring problems or is the MCU malfunctioning?
Just in case, I have ordered extra TM4C MCUs to test this.
