CCS/TMS320C6711D: Error connecting to target with CCS despite test connection passing

Michael Wells

Part Number: TMS320C6711D

Tool/software: Code Composer Studio

I'm using CCS 10.1.1.00004 and a Blackhawk XDS560v2 emulator. To debug this I've created the 'Hello world' example application. If I run Test Connection in the target configuration window I consistently get all the tests passing with no skips or failures. I have currently set TCLK to 5MHz though have also tried lower values. When I run debug I get 'Error connecting to the target: (Error -1060 @ 0x0)'. Interestingly if I enable the Debug Server Log in CCS support the hello world will then often start the debug session. However if I try this with my main application, even though the debug perspective may open, the debug commands (e.g. view memory) are unresponsive. Do you have any ideas or advice on what may be going wrong? I assume, as Test Connection consistently passes, I have a reliable JTAG connection but then why should this misbehave?

Any help much appreciated.

    Based on the fact the the 'Test Connection' passes and the type of error yo get when running only your main application, the issue appears to be application specific (caused by the target application). Please see the link below for more details on the error message and fore suggestions on how to resolve it:
