MSPM0G1507: About "TGTSUPPLYOUT" of XDS110

Hi Sal,

Thank you for your reply.

Q4: When using "Probe supplied power", is it okay to just connect "TGTSUPPLYOUT" and "GND"? Are there any other pins to connect?

Q5: Is it okay to connect "TGTSUPPLYOUT" and an external power supply to 3.3V at the same time?

Q6: Is there any information that this doesn't work if the XDS110 itself is old hardware?

In my environment, I connected "TGTSUPPLYOUT" and "GND" to V3.3 and GND of LP-MSPM0G3507, but "Error-267" occurs.
However, it can be connected if an external power supply is supplied to 3.3V.
I think that power supply conflicts may cause the current problem.

Best regards,

That is what I do, it works.

I don't think so.

I have no additional information on the old hardware.

While you can check the voltage output of "TGTSUPPLYOUT", maybe you choose a wrong pin of the TGTSUPPLYOUT.

Hi Sal,

I apologize. I was using the "Breakout Board" completely wrong.

I understood. Thank you for your support.

Hi Sal,

Sorry, I have an additional question.

Q7: Is it possible to stop the power supply from the XDS110 after "Program Load" in Uniflash?

In my environment, with CCSv20, the power is cut off as soon as Debug mode ends.
With Uniflash v9.2, the flashed program starts after "Program Load" and power continues to be supplied.

If you could confirm this, it would be helpful.

Best regards,

Hi OH,

The configuration in UNIFLASH doesn't take effect, see beleow generated ccxml files, it does not include power isolation configurations:

Below is CCS generated files:

So, I suggest you open the ccxml files with UNIFLASH: it works in my side

Hi Sal,

I have confirmed the operation with CCS v12.x and v20.x, and used a .ccxml file created with CCS, but the operation is unstable.
- Start a new session with Uniflash and flash as is. Power continues to be supplied after flashing.
- After flashing, physically disconnect the USB cable. If I reconnect it as is, power supply will stop after flashing.
- Start a new session with Uniflash, start and finish a Debug session from CCS. If I return to Uniflash and flash, power supply will stop after flashing.
- If power supply is stopped after flashing and another session is started with Uniflash, the problem returns.

I have tried restarting the PC, replacing the XDS110, and replacing the USB cable, but no change has been made.
The objective is to safely stop the power. If physically disconnecting the USB cable does not change anything, that's fine.

Best regards,

Looks like the first UNIFLASH operation of XDS110 will always keep power the device after loading firmware.

That something I didn't have a good idea, maybe UNIFLASH should take some operation to refresh its configurations.

I suggest you can check with "Tools" forum whether it is under expectation if you can stablely reproduce it in UNIFLASH.
