One suggestion from the page I have linked is to include the .retain line, but I am not sure where that line should go.

Hi Arafat,

In EABI, unreferenced variables will be removed in the linking stage. To retain such variables you can add #pragma RETAIN(symbol). This would make sure the variable is present i the .out file even though it is not explicitly used in the application code.

Can you give some details on the issue you are facing. Are you able see the variables in the expressions window? Are you not able to modify these variables from the code?

Regards,

Veena
