CCS/CC2642R: Updated TI Emulators to v8.1.0.00005 - CCS Crashes Every Second Debug Session

Part Number: CC2642R


Tool/software: Code Composer Studio

Recently had a colleague update his setup from bottom up (CCS v9, etc. etc.) and wanted to "catch up" to make sure compilers, emulator tools, etc. were on par between the two of us.

Upon working on some code today, I started a debug session. Things worked as expected, and I needed to make edits then re-debug the code again. I ended the debug session and began a new one just as before. This time the debugger gets to the point of programming and accessing the device at the reset vector, but then the entire program shuts down without a trace. Any changes to the workspace are also lost since the last successful close.

This is VERY repeatable and happens every second debug attempt I make after opening the project.

If I manually reset my PCBs, it shows that the new code has been downloaded to the device, but it remains that the debug session itself is failing. I have attached dump files and log files for the last two such issues.

I am currently running with:

  • CCS v8.2.0.00007
  • ARM Compiler Tools v18.12.1
  • CC26xx Device Support v3.10.10.02
  • TI Emulators v8.1.0.00005

I found in the properties for this emulator package that it was only tested with CCS v8.3 and above. Is there any reason that this package shouldn't work properly with CCS v8.2?

Is there a way to downgrade emulator packages back to what worked? I'd MUCH rather do that than re-download CCS v9 and start from the bottom up installation again.

  • Hello,
    This is a known issue that has been fixed in CCSv9.0.1:
    e2e.ti.com/.../2921244

    The issue occurs when you update your CCS installation to TI Emulators v8.1.0.0000x. It exposed a bug in the debugger that causes the crash. The debugger has been patched in CCSv9.0.1. We also plan to have an update for CCSv8.x with the patch if you do not wish to move to CCSv9.x. The patch will be CCSv8.3.1.

    And yes, downgrading the EMU pack in CCSv8.x will work also:

    Thanks
