DC/DC LED Lighting Kit

Hello:

I have followed the guide "HowttoFlash - dcdcLighting" to allow the GUI to work properly but I am having difficulty with my connection to the Target(F28035). All the jumpers and switches are configured correctly.

"Rebuild the Project" goes fine but when I try to do the "debug the active project" I get the error "An error was encountered when attempting to load the program".  In the console I get the following:

C28xx: Flash Programmer: Missing Flash Programming Settings

C28xx: Flash Programmer:  Error erasing Flash memory.

C28xx: Flash Programmer: Missing Flash operation option. Operation cancelled.

C28xx: Trouble Writing Memory Block 0x3f6f82 on Page 0 of Length 0x53

Cannot write to target.

I have CCS Version4.2.1.00004 and I have verified that I have the lastest Control Suite V1.9 software for the DC/DC LED Lighting Kit.  I have also verified that the drivers for the xds100v1 USB Emulator are the most current.  My computer is allocating COM port 18 for the Emulator.

Any help with this matter is greatly appreciated in advance.

Thank you

    jdp,

    I've not come across this error before, but hopefully I can help you get to a resolution...

    Firstly, I would try the below.  You've likely done some of it, but there's a good chance that doing all will fix your issue:

    1. Close CCS
    2. Restart your computer
    3. Restart Code Composer, but use a new workspace name (for example "DCDCLightingFlashforGUI").  Sometimes workspaces can get corrupted, so this may solve your issue.

    If that doesn't solve your issue, then unfortunately you may need to reinstall Code Composer.  This package can be downloaded from the link below.  Either the Full or Code Size Limited version should work with this kit.

    I'm sorry for the issues you are having.  Hopefully, you'll have a working kit soon.


    Thank you,

    Hi jdp,

    I've come across this error before with other projects and found that following the steps here will often resolve the problem: http://processors.wiki.ti.com/index.php/Troubleshooting_CCS Particularly look at the sections "General IDE" and "Debugger." I think Brett's suggestion of using a new workspace is essentially the same idea - something's gotten corrupted - but if that still doesn't work I'd try deleting the target database cache file (explained in the "Debugger" section) before going all the way to reinstalling CCS.

    Hope this helps!

    Regards,

    Katie

    Hello Katie/Brent:

    I followed through on all your suggestions and was not able to resolve my issues. 

    I finally resorted to a new CCS V4 install on a Windows XP platform.  The flashing issue went away.  The GUI then worked flawlessly for the kit.

    I was using a Windows 7 based computer when I encountered my problems.  I have had to do a complete clean Windows 7 installation on that particular computer.

    I thank you for your support and timely suggestions.  I only have these questions regarding the ease of the CCS application being corrupted.  Is this a significant problem and is it related more to Windows 7 than Windows XP based computers?

    Again, Thank you for your patience and time.

    jdp,

    I don't believe the issue is Windows 7 related.  We've had many customers use CCS4 with 7. 

    I have seen rare cases where CCS doesn't install correctly, but if installed again everything works.  If you need to run the board on the Windows 7 machine (w/ CCS4), you may want to try again.


    Thank you,
    Brett
