CCS/TMS320F28069M: Pointer variables in the debugger are truncated to lower half of register

Craig Mautner

Tool/software: Code Composer Studio

The debugger is interpreting pointers as just being in the lower half of the register. Notice in the screenshot attached that the Location for pEntry is "Register XAR3L"containing 0x0000ea64 rather than the full XAR3 which contains the actual pointer 0x3eea64. Similarly pObjEntry and pVarPtr are only shown as the lower halves of registers XAR1L and XAR4L respectively.

Even the listing file indicates that pEntry is contained in XAR3:

2635 ;* AR3 assigned to _pEntry

The code generated is correct it's just the debugger display that is incorrect. Is this something that can be corrected by a setting that I've overlooked?

Hi Craig,
There was a similarly reported issue (CCDSK-3134) that was never addressed due to a lack of reproducible test case. Can you provide one (project + source + generated *.out file)? Something very simple is ideal.

Thanks

My colleague pointed out there is another related issue that is being investigated: DBGTRC-4713. This one is still open but there is a reproducible test case so we don't need another one.

How can I subscribe to DBGTRC-4713 so that I can follow the progress? I tried searching TI for that number and came up empty.
