DESIGN GUIDE

Live Firmware Update Reference Design with C2000 Real-Time MCUs

Description

This reference design illustrates Live Firmware Update (LFU) without device reset on two C2000™ real-time MCUs, one with hardware features supporting LFU. LFU is illustrated on both the C28x CPU and the Control Law Accelerator (CLA). The software available with this design helps accelerate your time to market. LFU without device reset is an important consideration for high availability systems similar to Server power supply units (PSU), where downtime needs to be minimized. This reference design also has an example that illustrates Firmware Over-the-Air (FOTA) functionality.
