MSPM0G1507: Debugger issue

Part Number: MSPM0G1507
Other Parts Discussed in Thread: MSPM0G3507, , LP-MSPM0G3507

Tool/software:

Hi

We facing issue related to debugger mode. Main controller is MSPM0G1507 and XDS110 USB debug probe from LP- MSPM0G3507.

Connections as follows:

VCC(3.3V),GND, NRST, SWDIO and SWCLK pins from MSPM0G3507 to MSPM0G1507. The debugger suddenly disconnected and showing error message : "CORTEX_M0P: Error: (Error -1001 @ 0x0) Requested operation is not supported on this device. (Emulation package 20.0.0.3178) ".

Any issue with connections or any SW patch missing ?

Thanks in advance

Regards,

Yogesh.

    Hi,

    It seems that you are using the XDS110-ET on the LP-MSPM0G3507 to program your custom board with MSPM0G1507. 

    The issue you seen could related to the current consumption is high and exceed the ability of XDS110-ET. In this case, you may need external power supply to power up your board. And do not power from XDS110-ET then check the SWD interface again.

    Thanks Cash Hao,

    I am still facing some issues even if I give 3.3V from external power supply. 

    What should be connection for NRST . currently connected to 3.3V.

    Error code : "CORTEX_M0P: JTAG Communication Error: (Error -1001 @ 0x0) Requested operation is not supported on this device. (Emulation package 20.0.0.3178)"

    Error1: "CORTEX_M0P: Error connecting to the target: (Error -615 @ 0x0) The target failed to see a correctly formatted SWD header. The connection to the target may be unreliable. Try lowering the TCLK setting before trying again. (Emulation package 20.0.0.3178)"

    Hi,

    Try connect NRST pin to GND before powering up the MCU. Then power up the MCU. You can now try to program the MCU again.

    Thanks Cash Hao,

    I Tried to connect NRST of MSPM0G1507 and NRST of XDS debugger to GND  -- No change.

    if I connect NRST of both to 3.3V. I am able to load the program but debugging mode is still same issue (even  in this case also same error message but code is loaded at least).

    Thanks in advance.

    Regards,

    Hi,

    No need to connect the debugger's NRST pin to GND. Only connect the MCU's NRST pin to GND. For programming, you do not need to connect the NRST pin between the debugger and MCU. 

    You can program the chip but not able to debug? It is weird, which IDE you are using?
