Part Number: MSPM0L1305
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

 

Hi Team,

After flashing the code into the controller, it is not waking up. I removed and connected my debugger, and only then did the controller start running.

The TI team suggested that NRST should have a pull-up resistor of 47K. I have already added a 47K resistor, but despite this, I am still unable to wake up the microcontroller. This is urgent. Could anyone please help me with this ASAP.

    Hi santhosh,

    I checked your previous thread, I suppose the ervironment is remained unchanged. Please let me aware if there anything changed.

    It seems you enter a new problem, which is different with the previous thread.

    Currently it requires your manually reset to start the code, I suppose there should be some debugger behavior, sometimes it will halt the code running when it download firmware to device. There always could set the debugger to send a hardware reset to device to let mcu run the code.

    B.R.

    Hi Sal,

    Thank you so much, Any solution for this 

    We are expecting when the power-up code should run without a hardware reset 

    Can you please help me with this

    Hi Santhosh,

    How you download the code to the device?

    Using CCS with LOAD botton? Or, using UNIFLASH?

    Could you share me more details? I used to play with CCS and Uniflash, it could set some debugger behavior and do not need user's manually reset the device.

    By the way, could you share you VCC/VCORE/VSS/NRST partial schematic to me? I want to double check it.

    B.R.
