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?
