Profiling RAM usage of threads

Hello,

Sorry for the long response time. I was on my vacation last week.

Which Nordic board/chip are you trying with? Can you please try this sample from our SDK with Thread Analyzer module and see the output? You can find the same sample under ncs\v2.x.x\zephyr\samples\synchronization.

Please attach the screenshot after flashing.

Kind Regards,

Abhijith

Hello,

[quote userid="115767" url="~/f/nordic-q-a/93314/profiling-ram-usage-of-threads/401930"] The number says like the CPU is using 3258946%[/quote]

This is what I said

[quote userid="108934" url="~/f/nordic-q-a/93314/profiling-ram-usage-of-threads/393617"]Because I get junk data in thread analyzer that makes no sense.[/quote]

And wanted your help to solve this

Hello,

I said so because your number(%) look quite strange. The number says like the CPU is using 3258946% which doesn't make any sense as a single CPU cannot execute instruction more than 100% of the time.

Hello,

[quote userid="115767" url="~/f/nordic-q-a/93314/profiling-ram-usage-of-threads/395041"]From the screenshot you shared, the number doesn't make any sense(Like, thread using 100% of CPU). Seems that your CPU usage is OFF.[/quote]

Can you suggest how you mean Seems that your CPU usage is OFF..?
And how I can enable it..?

Hello,

From the screenshot you shared, the number doesn't make any sense(Like, thread using 100% of CPU). Seems that your CPU usage is OFF. I can also see some broken characters, like "::L" line breaks here and there. Are you trying with different modules for same UART?

Kind Regards,

Hello,

[quote userid="115767" url="~/f/nordic-q-a/93314/profiling-ram-usage-of-threads/393505"]I am not sure of why you are not using the Thread analyzer module.[/quote]

Because I get junk data in thread analyzer that makes no sense.
Like:

Can you suggest as to how I can rectify this 10 digit CPU utilization being shown..?

Thanks,

Hello,

I am not sure of why you are not using the Thread analyzer module.

May be you can use Tracealyzer for zephyr RTOS and Segger System viewer for getting this.

Hi,

Any other alternatives to RAM usage profiling other than thread analyzer..?

Thanks,

Hello,

You can make use of the Thread Analyzer Module from Zephyr.This Module enables the option to track thread stack size usage
