5.1 Overview

The following sections describe the bootloader commands and responses, as well as the ordered steps during image programming.

Because content and timing are important during the procedure, all steps were captured for reference. Saleae is the logic used. This utility is free for use and can be downloaded from https://www.saleae.com/downloads.

The image must first be created using UniFlash. Detailed instructions on how to create an image are listed in the UniFlash CC3120 and CC3220 SimpleLink™ Wi-Fi® and IoC Solution ImageCreator and Programming Tool User's Guide under Image Creation and Programming Using UniFlash.
