Crash dump facility on 6747

We’re diagnosing a failure with a 6747 design that takes days to occur. Are there any internal “crash dump” facilities available we can rely on?

    John,

    Tough situation.

    Are you running SYS/BIOS? DSP/BIOS? CCS with an emulator? Please tell us the version of these that you are using.

    Do you have a way in the software to detect the failure, or does it just crash and you have to turn it off?

    Regards,
    RandyP

    Thanks for responding.  We're using:

    CCS 3.3 SR12

    DSP BIOS 5.41.10.36

    CodeGen 6.1.20

    The occur on production build.  We have not had a failure with a unit on an emulator.

    John,

    I removed the Answered flag you put on my post above, because that would limit new advice coming in. People would see the thread as being answered and would not look at it to see if it needed an answer. I am not wording this well, but I hope it makes a little sense.

    And I will get this thread moved to the BIOS Forum instead of this C67x Single Core DSP Forum. The BIOS experts will know if there is anything to help you in DSP/BIOS 5.41.

    I fear that anything helpful from BIOS would be through CCS, though. I am just not sure. If you are not using an emulator, what controllability and observability methods do you have on your production systems in the event that we say there is a way to get a crash dump?

    It will help to give us some more detail on what "failure" means and what type of information you are looking for.

    Regards,
    RandyP
