    Which version of Code Composer Studio are you using? As you said this should work, but for stability I would suggest CCS 3.3 or later. Please let me know and we can continue to debug from there.

    Deepak,
    I think we need to look inside the default actions that CCS has enabled, to make sure there are no conflicts. If you right click on the .ccxml target config file, and click properties can you note what options are selected in both the "Program/Memory Load Options" as well as the "Auto Run and Launch Options"?

    Finally, if you disable the automatic real time; and just enable the real time manually after you are connected and loaded it is OK?

    Best,

    Mathew ,

    Please find attached build configuration screen shots for both the "Program/Memory Load Options" as well as the "Auto Run and Launch Options".

    with above settings I am getting below mentioned error while debugging.

    "Error connecting to the target:

    Error 0x80000204/-1137

    Fatal Error during: Register, OCS,

    It appears that the target is being held in reset.  This may be

    due to Wait-In-Reset (WIR) configuration set by the EMU 0/1 pin

    settings.  If this is the case, press Cancel and disconnect all

    connected devices to attempt to clear the WIR configuration."

    One more item to check; if you open the CCXML(double click) and go to the advanced tab, can you find this info as well:

    Deepak,
    If you dis-able the "auto" real time mode; and activate it manually in the CCS does it work/issue go away?

    I think there is still some conflict in when the IDE trying to set this mode and the state of the device with the other "auto-run" type options.

    Matt,

    As suggested I removed auto real time mode and tried activating it manually.I also suspended auto run and flashed the codes.after that i initiated real time with continuous refresh .On running it updates once and then running is getting suspended.

    Hi Deepak,

    Can you try launching a project-less debug session (see option #3 under "Launching a Debug Session") and manually connect to the target and then try enabling real-time mode? Let me know if it is successful or not.

    Thanks
