Lost ability to connect a SD XDS100V2 emulator to C6745 in CCS 4.2.4

I have a C6745 on a board designed at my company and am using a SD XDS100V2 emulator.  I brought the system up and was able to connect, but had a problem getting the code loaded due to a mapping problem.  Through making changes to map the code properly, I lost the ability to connect to the target and can not figure out where I broke the device driver.  Reinstalled CCS 4.2.4 and created a new target and still get

Error connecting to the target:
(Error -1265 @ 0x0)
Device ID is not recognized or is not supported by driver. Confirm device and emulator configuration is correct, or update device driver.
(Release 5.0.429.0)

Thanks, Jerry

    Jerry,

    This is a question for the Code Composer Forum and not this device forum. This thread will be moved there after my reply. Did you search the forum for -1265 or 1265?

    Open your Target Configuration file and make sure it is the right one for your emulator and your DSP. Then click the Test Connection button to see what information is provided there.

    Personally, I never use the bug icon to start a debug session because it does three different steps automatically, and if something gets mis-configured then things quit working. Instead, I always launch the Target Configuration from the View Target Configurations window so I know I am launching the right one. In my case, I have quite a few of them, for different emulators and CCS versions and devices and boards.

    When you Launch, CCS should switch to the Debug Perspective where you can see the emulator's scan chain tree. You can then right-click on the C6745 device line and select Connect Target. Then click on the Load icon below the menu line and select your program to debug. If you edit and re-compile that program, CCS will ask if you want to re-load it. I always check the Remember box and then Yes; it makes it very easy to make changes and see how they work.
