J-Link Errors

Hello all.  I am running IAR embedded workbench software debugger
through a J-Link connector to a TI TMS470.  I am getting an error,
"Failed to read current instruction" in a J-Link pop-up window when I
try stepping through the code.  After this, it will not let me
continue through the rest of the code.  I tried debugging in Simulator
mode and I do not get this error.  Has anybody ever encountered an
error like this?  As a note, the code did download completely to the
TMS470.

Thanks,
Rudy

Usually these kind of errors are related to hardware configuration  
changes, like:
* IO-pins needed by J-Link got hijacked
* the CPU clock rate changed

Try jumping over the offending code.

Thank you for your help.  I found that the problem had to do with some
initialization file that I did not include.  This was a low level
initialization file from TI.  This cleared up my error.  Thanks!
