MSPM0L1306: Could not connect to target

Daniele Nardi

Part Number: MSPM0L1306
Other Parts Discussed in Thread: SEGGER

I can't connect to device for programming anymore.

Using the Segger j-link-Ozone suite, I downloaded a firmware just once, i stepped-over the initialization function, then device stopped communicating with debugger and new connections became impossible.

Debugger console output is:

Addendum: from the reset PIN the following signal is coming out:

Hi Daniele,

Have you checked RTSET pin connection? this pin is connect to debugger? or floating?

Thanks!

Hello Johnson,

if you mean the NRESET pin, yes, it is connected to debugger and to a 47k pullup resistor

0 Johnson He over 2 years ago in reply to Daniele Nardi

TI__Mastermind 29716 points

Hi Daniele,

I guess this reset signal should from debugger, thus MCU can not run normally.

Maybe you can try to disconnect reset pin to see if MCU can run.

But I am not clear why debugger generate this waveform for RESET pin.

Thanks!

It isn't from debugger, it's there also when debugger is disconnected

Hi Daniele,

You means that the reset pin will be toggle when power even don't connect this debugger?

Have you download some code into this MCU? Like WDT code maybe?

And only one device? Or all device keep same phenonmenon?

What I'm more confused about is why the MCU RST pin keeps toggle. If you don't connect any debugger, this phenomenon is very strange.

For the waveform, this is captrue in Debuggwe download time?

Thanks!

Best Regards

Johnson

Hi Johnson,

yes, the pin toggles even when debugger is fully disconnected.

I downloaded some code, just the initialization procedure made by syscfg, pins read and pwm activation/deactivation.

The capture is in debugger download time, yes

TI__Mastermind 29716 points

Hi Daniele,

Do you have another MSPM0 to see if the reset pin is normal?

I think maybe the code issue cause MCU reset, for this device, you can try to keep PA18 High when MCU power on. This action will push MCU enter BSL mode rathan than run app code. This can avoid the app code issue maybe. Then try to download new code.

Does this issue occur in our paunchpad? or the borad design your side?

Thanks!

Hi,

the issue occurs on a board design on our side, I didn't try on a launchpad.

Thank you for the suggestion, I'll provide feedback as soon as possible.

Regards,

Daniele

Hi Daniele,

Please let me know if any test result from your side.

Thanks!

Hello Johnson,

sorry for delayed responde, but I've been on sick leave.

Unfortunately, the affected board is no longer available. I created a new configuration with a new one, this one is working properly. Checking the differences between the old the new configuration, the only difference I spot is the "configure unused pins" flag, which I did'nt assert on the new configuration: could it have been that? The reset pin left availablke on the Syscfg tool, then configued as output pin?

Hi Daniele,

After you try Johnson's suggestion, I also suggest trying the MSPM0_Factory_Reset_Tool (ti.com) if you have not tried it already.

Best regards,

Daniel

Hello,

the solution to power up with PA18 high is not working.

MSPM0 factory reset tool is not usable at this moment, because I'm not using XDS, I'm using J-LINK debugger

TI__Mastermind 29716 points

Hi Danriele,

Do you have any MSPM0 Launchpad in your side? There will include a XDS110-ET can run Factory Reset Command.

Thanks!

Hi!

I made it using the the XDS110-RT into my Launchpad and through CCS.
