4.1. Memory - C2000™ C28x Optimization Guide

Executing code from RAM is faster than executing it from flash. However, C2000 MCUs support code-prefetch and data caching while executing from flash to minimize overhead. For details on these features, refer to the "Flash and OTP Memory" section in the device Technical Reference Manual (TRM).

How do I load data/code to flash and run from RAM on a TI C2000 device?

The TI compiler provides an easy mechanism to do this automatically using the "ramfuncs" attribute. Follow the steps below: The shipping *.cmd (Linker command file) file of a specific processor already has allocation of sections of flash to store RAM data.
