==Booting options==
 
Diva module is built upon AM335x processor. This component supports several booting options that are summarized [[Hardware_Manual_(Diva)#Boot_Options|here]]. Reading of that section is recommended for understanding this document.
 
 
In general, AM335x ROM code creates a booting device list that are scanned for searching an available booting image.
 
 
===Available options===
 
Boot modes can be selected by S3 switches which acts directly on SYSBOOT configuration pins.
 
 
S3 switches are mapped to SYBOOT[3:0] pins allowing different boot modes.

Introduction[edit | edit source]

DivaEVB-Lite is a carrier board designed to host Diva system-on-module. It can also act as an adaptation board used in combination with Dacu carrier board. Therefore two different versions exist that are a little bit different.

The following picture shows Diva-EVB-Lite's block diagram when configured as standalone carrier board:

When used in combination with Dacu:

  • the following parts are not installed because their respective functionality is already implemented on DACU board
    • USBOTG port
    • RS232 UART port
    • PSU.
  • some wired connections are necessary; these are detailed in the Schematics section.
  • on J18 connector, a jumper must be placed on positions 1-2 and 3-4

Please note that Orcad CIS is required to get all the information about BOM variants included in .dsn files.

PDF files show the view of the default BOM variant used to manufacture the board. Components that are not populated are denoted as "Do Not Stuff".
