CCS/TMS320F280049C: Is there a way to see function and interrupt calls over time

Peter Kozlowski1

Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

On the MSP430 I can see the call of functions and modules in energy Trace+. I would like to get something similar for the C2000 to see how my functions and interrupts get called so I can better see where to squeeze some additional stuff into. I could do it on paper and calculate everything but I would prefer to be able to see the system behavior on the real system.

I don't need to get it in real time. I would not mind running an analysis over a second and then get an output that says "Interrupt1 was called at 1.54 microseconds and ran 3 microseconds"...something like that.

I am currently not running the TI RTOS so the RTOS analysis functions don't work for me.

Thanks

Peter

    Hi Peter,

    In C2000ware DriverLib example, there are some examples on profiling. One of them is "Profiling Interrupt". Please take a look.

    Thank you but this is not really what I was looking for.

    The ERAD module as used in those examples requires preconfiguration of HW break points and counters. I have 10 interrupts and 4 states with different durations and different interrupt calls. If I wanted to analyze them this way in all system states I would need forever.

    Just to determine the position and duration of each interrupt would require to run the program with a different ERAD configuration in each state for each interrupt. And even then I would not see if two interrupts switch places due to the change in a variable or external input. I have actually already done this using a pwm counter (reset counter at state machine start, get counter value at interrupt start, reset the counter at the beginning of each interrupt, get counter value at the end). But I had hoped there was an easier way.

    I was looking for something like this:

    Just with functions instead of peripherals.

    Peter,

    You will need TI RTOS to get the execution graph.  I do not think there is  have any other tools which will allow something like above.
