Abstract

Embedded processors often need to be programmed in situations where a JTAG debug probe cannot be used to program the target device. In these cases, the engineer needs to rely on programming solutions leveraging peripherals such as Controller Area Network (CAN) or Controller Area Network Flexible Data-Rate (CAN-FD), also known as Modular Controller Area Network (MCAN). C2000™ devices aid in this endeavor through the inclusion of several program loading utilities in Boot-ROM. These utilities are useful, but only solve half of the programming problem because they only facilitate loading application code into RAM. This application note 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 possible implementations for C2000 devices and provides PC utilities to evaluate the solution with.
