dsp56725 jtag scan error

Hi all,

I'm fighting with a DSP56725 and the associated Symphony Studio configuration for on-chip debugging via openOCD.

I've tried every configuration found in Symphony, but with no success; I receive an error message like:

 

Error:   jtag.c:1156 jtag_validate_chain(): Error validating JTAG scan chain, IR mismatch, scan returned 0x03ff

 

I connected the oscilloscope and I see that DSP react to the requests of Jtag, so this is not an Hardware problem.

Perhaps it could be a software problem linked to ID identifier for DSP56725; so, have anyone of you  tried working with DSP56725?

 

Have you got any problem with the openOCD with Symphony Studio?
