MSPM0L1306: Is there any tool different from CCS/Sysconfig that can set the SWD password in a production environment?

Hi Xavier,
Here is a quick guide on SWD Password. Here's one for Uniflash.

Hi Diego,

Unless I'm misunderstanding the links you provided, they don't answer the question whether there's an alternate method other than CCS/Sysconfig to set the SWD password in a production environment which is not supposed to use these tools. I'm assuming, then, that CCS/Sysconfig are the only alternative. Perhaps there's a way to build a custom script.

Hi Xavier,
Apologize about the confusion. Let me consult in my team if we have any information for setting SWD Passwords with scripts.

Hi Diego,

Xavier and I are also communicating offline (via email) and I do happen to believe there may also be a method for using (custom) gel scripts vs. the SW tools previously mentioned:

1. MSPM0L1306: Debug CCXML with SWD Password - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

Is it possible to check with the Apps Team to get further clarity?

TY,

Chris

Hi guys,
I'm still waiting for feedback from my team on this method. I'll let you know as soon as I get more information on it.

Hi guys,
It seems that the method we recommend is as follows:
1. Put the non-main configuration into the mass production firmware, and then program the M0
2. After programming, if there is no triggering of a reset that RUN BCR, SWD will still be unlocked (a programmer can verify the firmware)
3. Once a POR runs, the SWD should be password-protected.

Thanks Diego!  We appreciate the follow up here.  I've also notified the customer via email about your update.  Let's give it a day or two for a reply, thanks again !

Hi Diego,

Latest return feedback from customer:

Thank you for the investigation on this. I'm still not clear and would appreciate further clarification. See my comments below:

1. Put the non-main configuration into the mass production firmware, and then program the M0

• Is this done with Uniflash or another custom programming software/script on our end?

2. After programming, if there is no triggering of a reset that RUN BCR, SWD will still be unlocked (a programmer can verify the firmware)

• Is here where I should enter the password?

3. Once a POR runs, the SWD should be password-protected.

• What was the password used? I missed the step where I enter the password. 

I apologize if I'm overlooking some obvious steps. 

Thanks,

Chris
