CCS: CCS emulator issue

Tool/software: Code Composer Studio

Code Composer 3.1 Software used to check CRC's after programing fails to connect to desired DSP, this has been an on going issue and the problem keeps on persisting. Attached is an error message that pops up and there is no way to by-pass the error and connect.

Does anyone know what this error is referring to and how to fix this? The machine is running Windows XP SP3.

Thanks

  • David,

    The error message SC_ERR_CMD_HANDLE <-121> is an older error code that originates from the connection between the host PC and the JTAG pod - in other words, it can stem from problems in the USB port, the cable or the USB interface on the pod itself.

    Also, I would re-check the Windows Control Panel to see if there are any device driver issues.

    Apart from this, I would try to use selective replacement to try to pinpoint the problem - if you have a secondary port or host, that would be extremely helpful to try to isolate the problem.

    As a last resort, I would try to reinstall CCS to cover the highly unlikely scenario where the software itself (more specifically the emulation stack and drivers) have become defective.

    As you probably know, unfortunately these components (CCS, the JTAG Debug Probe) are not supported anymore and thus our ability to try to reproduce the issue are quite limited. A search around on the internet for the error message does not yield many troubleshooting tips as well.

    Hope this helps,
    Rafael
