CCS/LAUNCHXL-F28377S: TMS320F28377S

Part Number: LAUNCHXL-F28377S

Tool/software: Code Composer Studio

Hello,

I am using CCS 7 or CCS 6.2 and the LAUNCHXL-F28377S to test funcionality. I follow the 4 steps suggested in TI Resource explorer to import and debug the DEMO project example, but when i reach the 4 step (Debug the imported project) it doesn't work.

On the Debug window appear the follow message: ""Example_28377SLaunchPad [Code Composer Studio - Device Debugging]

Texas Instruments XDS100v2 USB Debug Probe/C28xx_CPU1 (Disconnected : Unknown)
Texas Instruments XDS100v2 USB Debug Probe/CPU1_CLA1 (Disconnected : Unknown)""

And, on the console window appear the follow mesage: "" Texas Instruments XDS100v2 USB Debug Probe/C28xx_CPU1 : Target must be connected before loading program.""

The launchpad is correctly set up and powered from the micro-usb connector. Also the XDS100V2 incorporated on the launchpad, is selected in project options.

I have verified connection with the correct processor and hit "Test Connection". All tests succeeded with the follow message:   ""All of the values were scanned correctly.

The JTAG DR Integrity scan-test has succeeded.

[End]""

I tried with both CCS versioon (7 and 6.2) and nothing. 

Please, help me to solve de problem. I can't test power of the launchpad to incorporate it to my project.

    Hi,

    The messages you mentioned are indicative of a disconnected core. When you launch the target, you can highlight the connection "Texas Instruments XDS100v2 USB Debug Probe/C28xx_CPU1", right click on it and select "Connect". This should allow you to load the code by going to menu Run --> Load --> Load Program

    I can't precisely tell why the core is not being automatically connected, but that should help you move further.

    Hope this helps,
    Rafael

    If you look at the CCS project properties under Debug -> Auto Run and Launch Options -> Launch Options is the "Connect to the target on debugger startup" option checked?

    If "Connect to the target on debugger startup" is not checked I think you will get the error "Target must be connected before loading program" when starting a debug session.

    Thanks for the suggestion. I did it that way and it works.

    Thanks, that solves the problem. So i don't have to connect every time I restart the project.
