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

==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.

|-
!S3 switch
!SYSBOOT pin
|-
| S3.5 || SYSBOOT3
|-
| S3.6 || SYSBOOT2
|-
| S3.7 || SYSBOOT1
|-
| S3.8 || SYSBOOT0
|}
<b>N.B.</b> bit set to 0 means DIP SWITCH has to be set to ON position.
==== Boot from NOR example ====
* SYSBOOT[3:0] = 0111 set S3[5:8] switches to ON-OFF-OFF-OFF

Same example can be found in the following table:

!Notes
|-
| 0111|| MMC0/SPI0/UART0 ||'''Default''' boot from NOR SPI
|-
| 0011|| NAND/NANDI2C/MMC0||boot from NAND
|-
| 1001|| SPI0/MMC0/EMAC1||boot from EMAC if DIVA has no NOR and no NAND on board
