Hi Janardhan,
I understand that you are facing an error when trying to build a model just to blink onboard leds with digitalGPIO and a pulse.
This "Values of NULL type cannot be expanded:" error can appear when the toolchain selected for the build process is 'Texas Instruments Code Composer Studio v3.3 (C2000)', the model uses a block from the c2000 support package, and the 'Target Hardware' option under 'Target Selection' is not set.
One possible workaround to resolve the issue is to select a specific board for 'Target Hardware'.
