MSPM0G3107-Q1: How can MSPM0 read out the Flash content after controlling the SWD port with PSW

xia-sanming

Part Number: MSPM0G3107-Q1
Other Parts Discussed in Thread: UNIFLASH, MSP-GANG

This requirement is mainly to deal with post-mass anomalies, you can read the code or save the parameters through the SWD port.

TI-GANG was tried, which could not read even though Unlocking psw was set.

The UniFlash does not see this action.

I wonder if there are any other tools or operation methods and processes that can be introduced?

Hello Sanming,

So you want to read out the Flash through MSP-GANG or UniFlash or any other tool after you have set password to SWD?

Best Regards,

hello Janz,

yes.I setup SWD password via nonmain memory options, and Program with the MSP-GANG successfully.

then ,I can't "Read" or "Program" through MSP-GANG unless "clear Locked device".

but if "clear Locked device",whole MAIN&NOMAIN memory was be erased.

so I can't get the code with normal operations(GANG or Uniflash).

Thanks

Hello Sanming,

UniFlash and GANG doesn't support SWD password function, but I will tell our software engineer and third party companies to add this function to GANG. And I will give you a script bout this function on UniFlash later.

Best Regards,

I resolved the issue for now by referring to your response in the following thread:
