Hi Nityanand,

While running out of flash, the ramfuncs section needs to be copied from Flash to RAM at startup. This is what we do in the "Initialize functions" section of the target preferences block while you pick a "boot from Flash" board. The ADC init routine needs it. Your code runs fine if I add this to the TP block. Attached is the modified model. Tips:

Use single instead of double as double is not natively supported on the c28x processor.
You can try printf in your MATLAB code, this will be cleaner instead of using direct ASCII characters.

I hope it helps,

Cheers,

Antonin.
