LP-XDS110: Pin 1 - Does it supply power?

Part Number: LP-XDS110
Other Parts Discussed in Thread: TMDSEMU110-U, MSPM0L1306, , CC2340R5

I recently purchased an XDS110 Debug Probe (TMDSEMU110-U) to program/debug our custom board, which features an MSPM0L1306 MCU. It is equipped with a standard ARM-Cortex Debug Connector (10-pin), as shown in the image below:

To interface with this, I used the CM10 Pin Adaptor that came with the debug probe to program the MCU on our board. However, it didn't work, and upon investigation, I discovered that pin 1 of the adaptor is NOT actually supplying power to the board. (I also found that the pin is named 'VTREF' instead of 'VCC'.)

Is the MCU expected to be powered up separately before programming/debugging it with the XDS110 Debug Probe?

Is there any way I can make the XDS Debug Probe supply power to the board so it can program/debug the MCU without an external power source?

Hi Nicholas,

Is the MSPM0L1306 MCU your targeted MCU which you are trying to program/debug? This is not a product supported by the LP-XDS110: https://www.ti.com/tool/LP-XDS110#supported-products

Still, it should be a valid XDS110 debug probe which I've just confirmed is able to program a CC2340R5 using only the 10-pin ARM connector. Note that the "TGT VDD" jumper must be placed across "XDS". https://dev.ti.com/tirex/explore/node?node=A__AA61vEN07olzwPR-lEYIaA__cc13xx_devtools__FUz-xrs__LATEST

Hello, Sorry I realized now that LP-XDS110 might not be correct. this is the standalone xds110 probe. And they are programming their own board.

In the following image is the board inside the "stand alone XDS110 debug probe" and I don't see the "TGT VDD" jumper anywhere on it. I think what you have sent me is a type of "embedded XDS110 debug probe" not the "stand alone XDS110 debug probe"
