no tasks or data on execution graph

Other Parts Discussed in Thread: TM4C129XNCZAD

Tiva TM4C129xnczad, TI compiler v5.1.10, TI-RTOS for TivaC 2.10.1.38, CCCS  Version: 6.0.1.00040

I've been able to run the demo's but cant get any execution graph from my own firmware.  When I pause and display the Execution graph there are no tasks/event shown - just a blank graph running to 100mSec.

In the "live session" and printf logs, I see several messages like the following:

1500672775,CORTEX_M4_0,"GPIO: port 0x40064000, pin 0x20 interrupt flag cleared",printf,Main Logger,,

1500681708,CORTEX_M4_0,UART:(@4000f000) Wrote character 0x13,printf,Main Logger,,

Is there a header file I could be missing?  A conflicting configuration?  

I read about possible Rta conflicts but Rta is not "added" to my system (checkbox).  However, if I click the tab belw from rta-module-settings to XDCtools, I see abort Fxn, puchFxn, readyFxn, flushFxn, exitFxn...

Finally, when this works, is there a way to stop/start the task switch capture dynamically?  I know the events that start the section of processes I want to follow and would like to start the capture of task/semaphore capture at that point and then stop when my process is done.

Thanks for all assistance!

    Hi Jack,

    which example are you running? I used the UART Echo example and I was able to see the execution graph. In this example, I saw context transitions as I typed characters into the serial terminal.

    Typically, TI-RTOS examples use the UIA Logging configuration by adding this to the .cfg file:

    /* ================ Logging configuration ================ */
var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');
LoggingSetup.loadLoggerSize = 256;
LoggingSetup.mainLoggerSize = 512;
LoggingSetup.sysbiosLoggerSize = 1024;

    When you open the .cfg file, you can find a graphical configuration page (Logging) that allows you to control several options. This wiki page (http://processors.wiki.ti.com/index.php/UIA_2.0_LoggingSetup#RuntimeControl) describes its runtime options.

    I can also get it running on the demo/examples.  However, now that I have my app put together, I cant see anything in the execution graph.

    I havent edited the .cfg file directly - it opens with the GUI.

    re-reading your post, I see your note on the runtime control. I have this configured to "always on". Apologies for not reading more closely the first time.
