We are using a XDS510 USB debugger with a TMS320C6713B processor on a custom circuit board. The DSP is working fine on our prototypes except for one aspect. When we try to connect the debugger to the target, it fails to connect about 80% of the time. When it fails to connect, we get the following error message:
Error connecting to the target:
Error 0x80000200/-1060
Fatal Error during OCS,
An unknown error prevented the emulator from accessing the processor in a timely fashion. It is recommended to RESET EMULATOR. This will disconnect each target from the emulator. The targets should then be power cycled or hard reset follwed by an emureset and reconnect to each target.
I/O Port = 510
Board Name: C6713 DSK via XDS510 USB Emulator
Cpu Name: DSP_C671x
Abort: Close Code Composer Studio.
Retry: Try to connect to the target again.
Cancel: Remain disconnected from the target.
Diagnostic: Run diagnostic utility.
The JTAG chain always scans correctly and passes all of the tests in the SDConfig utility. I tried a slower JTAG clock speed, but that had no impact on the problem. This problem is occuring on several copies of the prototype.
What are the possible causes of the "Error 0x80000200/-1060" error message?
