CCS unable to connect to C6678L core

Prodigy 100 points

I have a TMDSEVM6678LE board that has been working with the CCS tools.

Starting about a week ago, CCS tools can no longer connect to the core.

In the debug view window, the message is:

"Blackhawk XDS560v2-USB Messzanine Emulator_0 (disconnected:Unknown)
... the above repeated for all 8 cores.
There were other error message appeared on the Console window as well.
Details about my system:
EVM = TMDSEVM6678LE rev. 3A
CCS  Version = 5.2.0.00069 
GEL file version = 2.003

Thanks for helping.

    Hi Wing,

    Could you run the XDS560v2 diagnostics and post the results? Blackhawk should provide one that comes with CCS. I'd like for you to test your JTAG integrity outside CCS.

    Thanks

    Hi Ki,

    I have used "BH560V2 Config Utility" to test my EVM multiple times. They always pass. I have checked all test options: Reset, Scan Path, Run All, Integrity. All of them passed.

    I have attached the test log file.

    Thanks for your help.

    Regards,

    Wing

    Hi Wing,

    Thanks for the attachment. Looks like your JTAG connection is indeed fine.

    One thing to try is update your CCS version to 5.3.0. Hopefully this will help. If it does not, please reproduce the issue and send a debug server log. You need to turn this logging on. You can do it from the CCS Support GUI:

    http://processors.wiki.ti.com/index.php/Troubleshooting_CCSv5#CCS_Diagnostic_Logs

    Thanks

    Hi Ki,

    I have used CCSv5.3.0.00090, turned on the debug server log as suggested , and re-run my project.

    The log file "debugServerLog010313" has been attached.

    I have observed the following that might be helpful:

    * The result of each run is not necessarily consistent. The failure pattern varies ( with the same CCS settings).

    * I was even able to run the project successfully once or twice, but on repeat, it typically failed.

    * I swapped EVMs among my coworkers with various CCS versions. The runs typically failed, with occasional successes.

    Thanks for your help.

    Wing

    Hi wing,

    Thank you for the attachment. However, I only see the Eclipse Logs and Installation Logs. I do not see the debug server logs. You need to explicitly enable the generation of them as mentioned in the wiki article. Could you generate that log and send that to me?

    Thank you

    Hi Ki,

    I did turn on the "debug Sever Log", don't know why it is not included. I have tried again today. File is attached.

    I used the "Archive Logs..." button trying to save as a zip file, wasn't able to locate the .zip file. I have used winzip to generate the compress file instead.

    Hope it works. Thanks.

    Thanks. The log was analyzed and there definitely is some emulation failure. The debugger itself seems to be fine.

    Could you try one more thing? Could you clear all target cache files, launch files and also use a new workspace. I just want to see if that will help.

    How to do all this is mentioned below

    http://processors.wiki.ti.com/index.php/Troubleshooting_CCSv5#Debugger

    Thanks

    Hi Ki,

    I have followed the steps in the link, with a new workspace directory and cleared target cache files.

    The target configuration has been launched a few times, the reaction with the launch was not the same each time.

    Hope this run will provide the information needed to identify the problem.

    Thanks for your help.
