LP-MSPM0L1306: About Forced Reset

Part Number: LP-MSPM0L1306

Hi team,

When using LP-MSPM0L1306 and introducing the sample program timx_timer_mode_one_shot_standby.c, I get the following error and cannot write.
Even if I try the forced reset shown in CCS, the same error repeats and I cannot write, etc.
Is there any way to reset it?

Texas Instruments XDS110 USB Debug Probe/CORTEX_M0P Error connecting to the target: Device Connection Error. This could be caused by the device having gone to low power mode. Try forcing an external reset pressing the 'Force Reset' button. If the error persists, try: 1) Invoking BSL, 2) Calling a DSSM Mass erase, or, 3) Calling a DSSM Factory Reset. Check device FAQs for more information. undefined

    Hello,

    The easiest way to reset the device is:

    While the board is connected to the computer, hold down the NRST button (on the top of the board)

    Start a debug session (or flash the board)

    An "Error connecting to target" pop-up will appear in CCS with "Retry" and "Cancel" buttons

    Hold down the BSL button (on the left of the board)

    Immediately release the NRST button, immediately followed by the BSL button

    Select "Retry" on the error pop-up in CCS

    The Reset is timing dependent, and must be done fairly quickly. Please complete this process as fast as possible.

    The reset can also be done after the error window you are receiving pops up. This is done by following the above steps, but replacing "Start a debug session" task with "Click 'Forced Reset' option in CCS."

    Additional Information on why this is happening and the current solutions is available in the "Debugss_02" Section of the MSPM0_EarlySamplesFunctionalDifferencesV1p2 document available in your My Secure Resources > MSP-MSPM0_SDK folder.

    Thank you,

    Susan

    Hello Susan,

    Thanks for the reply.
    I tried the steps you gave me and it works.
    But why does this happen when I run "timx_timer_mode_one_shot_standby.c"?
    I also had the same problem when I executed "timx_timer_mode_pwm_center_stop.c".
    Is there any way to avoid this?

    Sincerely.
    Ryu

    Hello,

    Unfortunately, this an issue with the early samples. However, the issue has been fixed for the final silicon.

    Thank you,

    Hello Susan,

    Thanks for the reply.
    Does that mean it is impossible to improve with the evaluation board I have?

    Sincerely.

    Hello,

    If you asking if it is possible to stop the issue in the early samples, unfortunately there isn't a way to do so. We have a confirmed fix for the final silicon, so this issue won't happen with those.

    Thank you,

    Susan
