RTA not working with DSP/BIOS 5.42 and eZdsp C5505 USB Stick

Other Parts Discussed in Thread: TMS320C5505

I'm using CCS v5.5 + DSP/BIOS v5.42 and I have it hooked up to

a TMS320C5505 eZdsp USB Stick.

The Show Build settings and Target Configurations both are set to

C5500 family, USBSTK5505, and the connection is

Texas Instruments XDS100v2 USB Emulator. I also had enabled the following in the *.tcf file:

bios.enableRealTimeAnalysis(prog);

bios.enableRtdx(prog);

bios.enableTskManager(prog);

When I connect to device and load a program to run, the debugger says running.

But then when I try to enable the RTA, I see the both the RTOS Analyzer Configuration and RTA options are greyed out.

Does anyone know how to access the RTA (Legacy) option with the DSP/BIOS feature on that USB Emulator?

    Chris,

    Is the RTA enabled in the *.tcf file?

    Open the *.tcf file in configuration tool. Expand System, right click and select Properties.In the dialog box opened, make sure the Enable Real Time Anaylsis is selected (See highlighted text in image below).

    After enabling the RTA. Save *.tcf file. Rebuild project and debug. Now the RTA option should be available.

    In case you need to compare the settings, a good example to compare is the stairstep example.

    Vikram,

    I cut and paste the relevant portions of my *.tcf.

    utils.loadPlatform("ti.platforms.ezdsp5505");

    /* The following DSP/BIOS Features are enabled. */

    bios.enableRealTimeAnalysis(prog);

    bios.enableRtdx(prog);

    bios.enableTskManager(prog);

    So yes, I believe it's enabled.

    I might add that when I enable TI simulator, it works and I get appropriate screens,

    but when I use that TMS320C5505 ezdsp USB stick, it doesn't work, despite the

    configuration settings mentioned in my previous post.

    Chris,

    I am unable to reproduce your problem with my setup. 

    Along with the *.tcf config you shared:

    utils.loadPlatform("ti.platforms.ezdsp5505");

/* The following DSP/BIOS Features are enabled. */

bios.enableRealTimeAnalysis(prog);

bios.enableRtdx(prog);

bios.enableTskManager(prog);

    I see that Enable Real Time Anaylsis has to be set to true (please see my previous post on how to set this option). Setting it to true will add the following line to the *.tcf file:

    bios.GBL.ENABLEINST = 1;

    With these settings, I am able to use the appropriate RTA menu options.

    Another option that you could try is to build the stairstep example for the board and check if the RTA is working. RTA is pre-enabled in stairstep example. This example could help in debugging the missing settings in your *.tcf file.
