CCS/AM4376: CCS Cannot open output file to build

I am debugging using the built in debug tools, with XDS-200 ISO via USB. My output file is around 7MB.

Hi Arun,

This issue has been reported in the past. The most common causes of this issue is one of the below:

-aggressive antivirus software. Can you try disabling it temporarily and see if that resolves the issue?

-if the above does not help or does not apply, it may be an issue of a corrupt CCS installation. Please try uninstalling CCS and the reinstall it (make sure the directory is completely empty before reinstalling).

Thanks

I've disabled AV as per the other thread, and I've seen this in CCS9.3 and 10. I upgraded to CCS10 maybe 2-3 weeks ago, this started happening a few days back. I can re-install but I dont think its a problem with the install per se. I say that as I can do everything as normal till I have a debug session and then this issue happens

I see this when I close CCS10, image attached

Can you try cleaning your workspace folder?

Tried cleaning Workspace folder, still happens.. 

For some strange reason, the debugger seems to keep a handle on the out file despite shutting down the debug session. I've seen this issue reported in the past multiple times but the root cause was never really determined.

Can you try clearing the cache as described in:

Also, what happens when you try to rebuild the project while the debug session is active? This should be allowed.

Can you also try some basic project that uses the TI compiler (can be any simple basic project)?

Thanks
