Hi,
Thank you for your interest in TI products! In order to solve your problem more effectively, I need some more time to look at this chip, which will be answered for you later.
Hi,
In fact, both CCS and UniFlash can read out the trace ID. please check whether the chip you bought is the release version.
my c-code is:
volatile uint32_t sMCU_TraceID = 0;
sMCU_TraceID = *(uint32_t *)0x41C40000;
Hi,
1). Where and When customer bought the chip;
2). Can you take a photo of the silkscreen of the chip;
3). If you read out the data at 0x41C40004, what will you get;
Best Regards,
the read out data of 0x41C40004 is '0x0BBA102F'.
Hi,
When did you purchase these chips from?Did this chip come from an earlier time when someone from TI helped apply?
Are you mixing release versions with previous versions?
from 'Taobao.com' this year, a Evaluation Boards of LP-MSPM0C1104, it says only for college competitions.
this is my first time using MSPM0 chip, so i brought this Evaluation Board to learn.
Is the chip on this board an original or a test version? Not the official release version.
Hi,
If it is a release version, it should be REV B, we cannot guarantee products purchased from other sources, and it is recommended that you consult your purchase channel to deal with follow-up questions.
got it. thank you very much!
If it's a release, my C code can read a valid TraceID.
