TMS320F28027F: Probe supplied Power Mode but unable to debug and program using XDS110 debug probe

Part Number: TMS320F28027F

Hello 

I am using XDS110 debug probe with TMS320F28027F controller. In Target Configuration tab, I configured the Power selection to "Probe supplied Power " voltage to 3.3V. 

But following is the error occurred...

[Start: Texas Instruments XDS110 USB Debug Probe_0]

Execute the command:

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

[Result]

ccs1031\0\0\BrdDat\testBoard.dat

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

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioxds110.dll'.
The library build date was 'Apr 29 2021'.
The library build time was '17:49:40'.
The library package version is '9.3.0.00058'.
The library component version is '35.35.0.0'.
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 '-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]

 

I have connected TMS, TDI, 3V3, TDO, TCK, TRSTn and GND pins 

Connector used -  CTI20(IN)-TI14(OUT) JTAG ADAPTER

Following is Screenshot of Target Configuration - 

After saving and configuring the debug probe, 0V is measured across 3V3 and GND pins

    Have you looked at the debug tips in http://www.ti.com/lit/spracf0? Also, please provide some details on your H/W. If possible, provide the schematics that shows all the connections between the JTAG connector and the MCU.

    https://www.ti.com/lit/SPRUI94 says “the XDS110 JTAG header is connected to the target for debug, and the XDS110 AUX cable is used to supply the power. The TGTSUPPLYOUT and GND pins on the AUX connector (refer to the Figure 3) are connected to the supply pins of the target.” What do you measure between TGTSUPPLYOUT and GND?

    I am able to measure Voltage across TGTSUPPLYOUT and GND = 3.3V. But same following is error message -

    Execute the command:

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

    There is barely any information in the schematics you provided. You could send more details privately to me, if you don’t want to post it on e2e. In this case, please send me a friendship request first. I don’t know what else is on your board but there is a limit of 400 mA that you can draw from the debug probe. 

    Have you measured the voltage directly at the device pins? It appears your board has the provision to inject an external voltage. Have you tried that option?

    - Yes, it is 3.3V

    I have replied. Let us continue the conversation only in the private chat. No need to follow-up here. We can always post the resolution here, if need be.
