TI Friends & Family,

We need to ask for some guidance on the MSPM0L1306 our customer is using. They are nearing production release and am trying to finish up some aspects of the FW. They are currently trying to figure out the best way of Read protecting the Flash but still allow reprogramming to occur through the SWD even if a full chip erase is required first. They developed the project in Keil and installed the latest SysConfig version but are still not real clear on the right way to implement the security. They are using SDK 1_00_00_04 with Keil 5.38.

TY,
CY

Hi CY

SWD password in CCS is the feature you need. but this feature is not supported on Keil so far. it is supported by CCS.

Please refer to this document:

4113.How to use SWD password in CCS.pdf

Thanks

Hi Xiaodong,

Thanks for the help with this. Is there a way the customer can generate the configuration file/password file in CCS, and use that in Keil? They're apprehensive to move their project from Keil to CCS.

Thanks,
Darren

Hi Xiaodong,

Is there any workaround here that would allow them to continue development in Keil?

Thanks,
Darren

Hi Darren Jenkins

SWD password is based on CCS script. So far, it is only supported on CCS.

Thanks

Hi Xiaodong,

I had another internal discussion where it was advised that we could copy the sysconfig generated file into Keil. See documentation here:

Thanks,

Darren

Hi Darren Jenkins

This discussion is on the sysconfig. it is different with CCS script.

May I know if you can follow this discussion to realize the SWD password on Keil through copy the file?

Thanks
