MSP432E401Y: TIMER IS STOPPING AFTER CERTAIN TIME

Hi,

 Is it only the timer task not executing?

I suppose you have several more tasks set up in the beginning? Are the rest of the tasks running?

Is the processor trapping in any error?

Can you use ROV to find out the status of each task? 

Hello Charles,

Thank you for the response.

I am not able to connect to the ROV and getting the error as shown below.

what is that missing extension?.

Thank you.

Regards

Kalyan.

Hi,

  I will forward your question to our CCS expert for comments. 

Hi Kalyan,

What RTOS are you using with your application?

Thanks

Hello Ki,

I'm using TI-RTOS in my application and Timer ID: 0.

Thanks

Just a random thought - something that has caught me out before, with similar symptoms.
If you have configured DHCP, but not connected a server, the DHCP task will time out after about 2 minutes.

The default implementation then goes into an infinite loop, blocking out all lower priority tasks.

Also, anything that generates an exception goes to some default handler code - if you halt the debug, and it is at a line of assembler with a comment "spin here forever", something has had an exception. It is really handy to get the ROV working as it will tell you if any task has exceeded its stack (a common cause), and, which task was active when the exception occurred. The call stack  for that task will often reveal the problem function.

I have noticed that the ROV can be a bit tricky. Sometimes, it just needs a few attempts to start, or close and restart.

Can you get ROV to work with other TI-RTOS examples such as ones from the MSP432E SDK?

Hello Ki,

I'm getting the same error with the "adcsinglechannel" example from SDK as well.

Thanks.

What exact CCS version are you using? And what version of the SDK?

CCS Version: 12.4.0

SDK Version: 4_20_00_12

I used the same example with those versions and ROV worked fine.

The error message you are getting looks like ROV is having issues communicating with our cloud agent service that comes with CCS. Can you try opening Resource Explorer and see if that works ok? Resource Explorer also communicates with the same service.
