Streamline - Bare Metal - Function/Call Paths view not showing function names

Hey! I am working on Streamline Performance Analyzer for Bare Metal Support. 

Generated Barman files (Linear RAM Buffer) for cortex - R7 with 7 PMU counters, compiled them separately with armcc to create a library file. 

My project code is also compiling with armcc and to enable the frame pointer, I have used --use_frame_pointer instead of --fno-fomit-frame-pointer as it is used for armclang.

The readings for PMU counters are visible in the timeline view, but the function view, call path view and code view are not showing function names rather only one function row with unknown_code_in_unresolved giving the complete 100% to its execution.

I am using ultimate version for DS-5.v5.28.1 for streamline. 

Compiling my code on a different platform. Executing the .axf generated (after compiling) on my target and storing the buffer generated into a .raw file.

Does anyone know what is it that I am doing wrong?

Attached are the function and call path views   image.

  • Hi Anudhi,

    Thank you for getting in touch. Would it be possible to know the steps that you went through when you generated the barman.c and the barman.h files? As well as where you are putting your instrumentation in your code. The more information we know about your system the better.

    At the moment the worrying things are that you are only collecting 1 sample for the whole system. Is this expected or another system of your issue?

    A few more questions that will help us diagnose your issue:

    How are you sampling are you calling barman_sample_counters or barman_sample_counters_with_program_counter?
    What arguments do you pass your sampling function?
    Does you .axf file have symbols?

    When setting up barman.c and barman.h what did you set your max mmap layout records to?

    There is an introduction video on how to use the Streamline Bare-metal feature that may help located here: developer.arm.com/.../streamline-bare-metal

    One final thing: If you are using DS-5 Ultimate with a licence you are entitled support and you may get a quicker resolution using those support channels.

    Hope this helps,
    Stephen
