About this manual

This manual focuses on software usage on SPEAr development boards and is organized as

a sequence of chapters going from a description of the first step and then covering more

complex subjects.

Step-by-step approach to using the manual

This guide applies to all currently available SPEAr evaluation boards.

However, each different evaluation board is based on a specific member of SPEAr

embedded MPU family and provides, in general, a different selection and combination of

hardware devices on the board (and companion boards, wherever applicable). For a

detailed description of hardware features for each evaluation board, please refer to the

corresponding evaluation board user manual.
