==Introduction==
[http://www.dave.eu/dave-cpu-module-am3517-lizard.html Lizard] is a system-on-module that belongs to [http://www.dave.eu/files/roadmap.pdf DAVE's ''Esatta'' Line product class].
 
 
[[File:Lizard-lelk.jpg|400px|frameless|border]]
 
It is based on Texas Instruments AM3505/AM3517 ''Sitara'' processor. [[Hardware Manual (Lizard) | Lizard Hardware Manual]] provides detailed information about hardware interfaces and characteristics. This document will provide a functional overview of the module and will focus on system-related issues.
 
==Module overview==
The following picture shows a simplified block diagram of Lizard module.

==Hardware==
===Power-up sequence===
Most of complexity of Lizard power supply unit is implemented on Lizard itself. However please read carefully [[Power-up sequence (Lizard)]] that provides some suggestions about carrier board design.
 
===Reset scheme===
Lizard provides several different resets signals. Please refer to [[Reset scheme (Lizard)|Reset scheme]] for more details.
===Memory organization===
Lizard memory organizaton is detailed [[Memory organization (Lizard)|here]].
===I2C busses and peripherals===
Please refer to [[I2C busses and peripherals (Lizard)|this page]] for more details.
 
===CAN interfaces===
Please refer to [[CAN interfaces (Lizard)|this page]] for more details.
===Power consumption===
Please refer to [[Power consumption (Lizard)|this page]] for more details.
 
==Boot sequence==
By default, Lizard tries to load boot code (boot sequence) from the NOR flash.
 
For more informaton about boot sequence options please refer to [[Boot sequence (Lizard)| Boot sequence]].
==Integration guide==
[[Integration guide (Lizard)|Integration guide]] document provides useful information and resources that allow the system designer to integrate Lizard module in his/her application very quickly.
 
== Software ==
The following operating systems are supported.
===Linux===
[[File:Tux.png|50px|left]] <br> [[Lizard Embedded Linux Kit (LELK)]] is the complete development tool to allow user to start evaluating [[:Category:Lizard|Lizard]] SOM.
 
 
=== Android ===
[[File:Android-logo-full.jpg|50px|left]] <br> <br>Please refer to [[:Category:Android|Android ]].
 
 
===Use cases===
