LP-MSPM0L1306: 2.5V programming using XDS110 Debug probe

Please have the actual physical connection with pin number

Hello Selvam, 

Thank you for contacting us. For clarification here, pin 2 of the Target Board indicates MCU 2V5 which I presume refers to 2.5V. Furthermore, on the table you provided, VTREF stands for Voltage Reference which is configured as 2.5 or 1.4 on the MSPM0L1306. Kindly let me know if that provides clarification

Regards, Jojo

Hi Jojo,

Thanks for the response.

You are correct, MCU 2V5 is refers to 2.5V.

Based on input regarding VTREF, updated the connection as below, please validate and correct if any mismatch.

Also guide us about how to set "Target Voltage-2.5 or 1.4" in Code composer studio while connecting with XDS110 Debug Probe.

Thanks

Hello Selvam, 

Thank you for your feedback. However, want I wanted in this scenario was just a clarification. Regarding your setup, you have a Target Board and you are using your TI14 pin adapter since the XDS110 probe uses CTI20. 

Based on the initial pin layout of your target board above, this makes sense. However, if you want to supply power from the XDS110 to the target board's MCU 2V5, you will need to use the aux port of the XDS110 for this. This is referenced in section 3.1.2 Probe Supplied Power of the XDS110 user guide linked below:

The Probe can supply the target with power from ranges of 1.8V to 3.6V so 2.5V is within range. Kindly let me know if you have further questions or concerns.

Hi Jojo,

Thanks for the details.

So, We need to use two ports (Debug port for signal lines and Aux port for power supply)

Below is updated connection diagram from understanding, please correct me, if any mismatch.

Section 3.1.2 of XDS110 user guide shows the options of target voltage setting, not clear about from where we can reach this option,

like from which menu we can reach this option of "setup power source control", May I have that details?

Thanks

Selvam

Hello Selvam, 

Yes, your diagram looks right. Also, just to be clear, the section you should be referencing is 3.1.2.2 since the probe will be used to supply power to the target device. Moreover, you will need to create a target configuration file File -> New File -> "name".ccxml. With this file created in your project, you can configure the device as such. I recommend watching the video below as "probe supplied power" is also configured in this scenario.

Kindly let me know if you have further questions or concerns.

Hello Selvam, 

Good day. Just checking in on whether there are any updates on this. If so, kindly let me know.
