I have defined the _LAUNCHXL_F28379D in the setting now its working , but still i need example with printf().

if i tried to use he stdio.h to use printf i get some error.

    Vikas,

    The linker is giving this error because it does not have enough memory defined for the program space to hold the code.  I would recommend allocating some/most of the code to flash memory vs RAM as there is much more space available.  The penalty for executing from Flash vs RAM is not so great on our devices due to some prefetch buffers, etc.

    Once you do this, you can also view the .map file to see how much memory is being used, we could then look to put some partition back in RAM if that is needed.

    You should see an example in C2000Ware where the code is loaded to flash, CCS can parse the addresses and will program the flash for you on program load.

    Best,

    Matthew

    Vikas,

    You just changed the build config to CPU1_FLASH, correct?  

    Since this is a different build you will need to re-add _LAUNCHXL_F28379D to the predefine list in the project properties.  Likely this is the issue, if this is not predefined the assumed input clock frequency is different(assumes control CARD settings).

    Best,

    Matthew
