CCS/TMS320C6748: Can't Connect to 674x DSP on TMS320C6748 board

Part Number: TMS320C6748

Tool/software: Code Composer Studio

I'm having trouble connecting my spectrum digital XDS100v1 USB emulator to the 674x DSP. I've setup a CCS4 target configuration based on the TMS320C6748 board.
 
I'm get the following error message when I debug or try to connect to the target:
 

Error connecting to the target:
Error 0x80000240/-1180
Fatal Error during: Initialization, OCS,
The target is being held in reset. The applied reset must be released before progressing.

 
 
Any advice to help me bring this board up will be much appreciated.
Thanks,
Biswajit
  • Biswajit,

    Can you double-check if your target configuration file is correct? The reason is that this error message sometimes happened if you configured the connection to XDS100v2 and not XDS100v1.

    Also, the message indicates the device is being held in reset. Can you double-check all the hardware (clock pins, proper power, etc.) to see if the device itself is running correctly?

    One good reference to evaluate if the core itself is in a bad status is section 3 of the following page:
    processors.wiki.ti.com/.../GSG:Connecting_to_slave_cores_in_SoC_devices_v5

    Also, is there a particular reason as to why you are using a CCSv4 release? Keep in mind this was not tested in more modern operating systems such as Windows 8 or 10 and therefore the ability to connect may be impacted.

    Hope this helps,
    Rafael
