CCS/TMS320F28335: Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator_0/C28xx : Target must be connected before loading program.

Part Number: TMS320F28335

Tool/software: Code Composer Studio

Hello,

I am using the EZDSP with the TMS320F28335 device and am having trouble uploading my program to the dsp. I am confident that my drivers are up to date and my ccxml is correct. I have uploaded numerous projects to the same dsp (recently, within a week ago) with the same setup but there seems to be a problem with the current project I am working on that I just cannot figure out.

It seems like I have tried most of the steps here: http://software-dl.ti.com/ccs/esd/documents/ccsv7_debugging_jtag_connectivity_issues.html with no success. The project builds fine but gives me this error after I press the debug button "Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator_0/C28xx : Target must be connected before loading program."

Can someone please explain what is going on here?

    Hi,

    The error message is consistent with a misconfiguration of your project and/or a specific procedure.

    For example, the top right of your first screenshot shows the F28x core disconnected. Highlight it, right click and select "Connect". 

    The project itself may be misconfigured. Can you check its debug options and see if you have a Connection selected at its General Properties and the option Connect to the target on debugger startup is enabled? 

    Check the sections 6.1.3.1.1 and 7.2.5 of the CCS User's Guide (available at the CCS Help --> Contents) or at the link below.

    Hope this helps,

    Rafael

    Rafael,

    A much easier fix than I thought it would be. Thank you for your help! All I had to do was select the "Manage the project's target-configuration automatically" option in the Properties -> CCS General -> Device Section. A before and after image are below. Thanks again.
