GEL Function

I am using Windows 7 (Service Pack 1) , Code Compressor Studio 5.5.0 and Board TMS320C6713 DSK.
Currently, I am testing the example code from the book 'Digital Signal Processing and Applications with the C6713 and C6416 DSK' by Rulph Chassaing and I would like to test the GEL function. 

GEL Files is loaded.

Yet, the changes would not be applied even though the slider is moved while the processor is running. 

It keeps showing it cannot be evaluated and could not write the address. 

Am I missing something in order to apply the GEL file ?

    Hello,
    The issue is that for targets that do not support real-time memory accesses, GEL is intrusive and requires the target halted to access memory. Since the target is running and your target does not support real-time memory accesses, GEL is unable to access memory. Hence "Execution state prevented access". The example you are following is likely written for a very old version of CCS since that book has been around for a long time. Likely CCSv3 or earlier. In those old versions, CCS would automatically halt the target before any memory access and then resume execution after the access. But in your version, CCS does not do this by default. If you want to change the default behavior, go to 'Tools -> Debugger Options -> Auto Run Launch Options' and enable the first checkbox 'Halt the target before any debugger access' and press the "Remember My Settings" button (to preserve the setting for future debug launches).

    Thanks
