MSPM0G3519: Factory reset using command line.

Mehul Dabholkar
Intellectual 595 points

Part Number: MSPM0G3519
Other Parts Discussed in Thread: UNIFLASH,

Hi guys, 

I am utilizing standalone command line functionality of uniflash to generate pkg of executables. I have seen that if i use/configure nonmain region in code and program that code. next time without doing factory reset i am not able to program a device. 

Why do i need to do factory reset in this case?

Second thing if it is mendatory to do factory reset then what command sequence is use to do that? Is there any other way todo factory reset other that UNIFLASH?

    Hi Mehul,

    A factory reset should only be required to override static write protections set in place if the application is attempting to overwrite the protected main and/or nonmain sectors. What configuration changes are you making to Non-Main?

    Also, what erase method are you choosing? In my testing, I successfully reconfigured non-main without a factory reset when using the following option:

    You can send DSSM commands over SWD to factory reset the device. Section 4 of the Hardware Programming and Debugger Guide for MSPM0 goes over DSSM commands.

    Best Regards,
    Brian

    Ok but I am writing a script and, in that script, I want to do factory reset first before flashing new code. How can I do that?

    I have done some BCR config changes in nonmain like SWP, disable bsl invoke pin etc.

    Same erase method I am using as you shown in picture.

    Hi Mehul,

    The following script can be run from within the same directory as the dslite script and performs a factory reset on the connected MSPM0G3519:
