ADSP-SC584 ARM core hangs

Category: Software

I am having some strange behaviour withthe ARM core on the ADSP-SC584. I have the issue that the core hangs at random moments. When this happens the debugger can no longer get any usefull information out of the core. If i read out the registers i get garbage data and same for the memory.

See screenshots.

However, the SHARC cores are still working as expecteced an i can still read out the the memory with the debugger through these cores. I have verified that there is no stack or heap corruption for the arm core by reading out the memory that way. I have also verified that the DDR ram is working properly by running a stress test for the ram without any issues.

I would expect that if there is a any exception which would cause the core to hang, the prorcessor would trigger the exception handlers. But this is not the case in this situation. I have tried to manually reproduce this behaviour by writing any buggy code i could think of, but this always triggers the exception handlers as expected, and never ends up in a state where the core just hangs.

Any idea what could be the possible reason for this behaviour?

I am using CCES 2.10.1 with the ADSP-SC584 on a custom board.

  • Hi,

    Could you please let us know whether you facing this issue in this specific project? If so, please let us know which application/example that you are trying to run from Sigmastudio for SHARC.

    Which version of Sigmastudio for SHARC that you are using?

    Did you tried in any other machine? If not, please try and let us know whether you are facing issue there.

    Is it possible for you to use latest version of CCES 2.11.1 and try running the example?

    Awaiting for your reply.


  • We are running an application which was built starting from the DemoUc example included in sigmastudio. Currently we are using Sigmastudio for SHARC 4.7.

    I have not tried it on another machine as i believe the license that i am using is node locked.

    Can i update to 2.11.1 without license or compatibility problems with SS for sharc 4.7?

  • Hi Robrecht,

    From our records, we seen that you have active subscription for your license, so you can install and use CCES 2.11.1 without any issue. The previous license file will apply automatically for this version of CCES.

    You can download and install CCES 2.11.1 from the below link.

    If possible, please try change the workspace in CCES 2.10.1 and import your project and run.

    Please try these at your end and let us know the result.
