Abstract

Embedded processors often need to be programmed in situations where JTAG cannot be used to program the target device. In these cases, the engineer needs to rely on serial programming solutions. C2000™ devices aid in this endeavor through the inclusion of several program loading utilities in ROM. These utilities are useful, but only solve half of the programming problem because they only allow loading application code into RAM. This application report builds on these ROM loaders by using a flash kernel. A flash kernel is loaded to RAM using a ROM loader - it is then executed and used to program the target device's on-chip Flash memory with the end application. This document details one possible implementation for C2000 devices and provides PC utilities to evaluate the solution with.
