==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 Performance Line product class].
 
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 interfacesUse cases===Please refer to [[CAN interfaces (Uses cases with Lizard)|this pageEmbedded Linux Kit]] for more details.===Power consumption===Please refer to [[Power consumption (Lizard)|this page]] for more details.
==Boot sequenceMisc==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= TI Online Workshop ===[[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 supportedLinks to Texas Instruments training material related to the AM3517. Though not Lizard-based, they provide useful information.===Linux===[[Filehttp:Tux//processors.wiki.ti.png|50px|left]] [[Lizard Embedded Linux Kit (LELK)]] is the complete development tool to allow user to start evaluating [[:Category:Lizard|Lizard]] SOMcom/index.=== Android =======Use cases====Please refer to [[Uses cases with Lizard Embedded Linux Kit]php/AM3517_On-line_Workshop TI AM3517 Workshop material].
