MSPM0L1305-Q1: M0L1305QRHBRQ1 PIN PA18(A7) function is changed

Hi Larry,

Does your code change the Nonmain, it seems that you have disable SWD port.

Regards,

Zoey

yes, the non-main code is changed. why do you think the SWD port is changed? we don't think so.

if the Nonmain has been changed in code, that’s make sense why you have seen that the Nonmain is modified. So what’s your concern here?

And for the SWD issue I said, I see this address seems to be the SWD function configuration address. I might count wrongly. Please ignore this.

Hello Zoey, now due to the BSL function is from disable to enable, our product is lose the LIN communication. So, please give us some proposal which scenarios can lead the non-main sector data changed? at the same time, please call me or you can tell your phone number, i think we can discuss together with phone, that is high efficient than E2E forum. Thanks.

You can do factory reset if you want to change the Nonmain back to default. 
have you changed Nonmain in your own code????please let me know. 

please call me directly. Thanks.

As my question, we define the PA18 as ADC port, so we have disable the BSL function in our software code. After receive customer's complaint parts and read out nonmain data found it is changed.

To disable BSL, you need to change the Nonmain. So that’ why I said this make sense. 

HI ,Please see my first question: i have mention all ok prats we have changed the Nonmain data. now we want to know why the complaint parts nonmain data is changed by itself? which case can lead it change?

I see 0x000A address is also changed 

If this happens not as expected, then the reason would from:

• During flashing, there is some disturb to affect the transmission. But seen from the image comparison, the NG image seems to be regular not random. Seems like it is configured by software.
• based on #1, that’s reason that I always let you check that have you flashed the another version or wrong code.

I am OOO with no laptop, you can check the TRM by yourself to see the meaning of modified register. 

we  also double check with our programming tool supplier, and check with them the programing station can verify during programming. our supplier don't think the programing station can have some influence for nonmain data changed. 

when you are return to office, we will discuss together on line as your colleague also mention.

Few days ago, i have try to wrote simple software for another similar product which disable and enable the BSL invoke. we can see it is  the same with the complaint issue(see below picture). And the same time, we also check the empty parts which haven't programming, the nonmain data is same with the enable BSL invoke. That means maybe the complaint parts restore to factory mode we guess.

Hello Zoey, as you said, you hope we can double check the nonmain data after re-power when the programing is finished. How long do you think should be waiting between programed finished to re-power double check nonmain?

I don't think there's a time limit.

Also, I'm starting to suspect that is there any possibility that the flash vendor might have forgotten to perform the verify process in this batch?

We have checked current program tool can recognize the non-main sector data is wrong when we connect the NG part via click “verify” button this afternoon.
