=== DIVAEVB-Lite plugged on Dacu ===
=== DIVAEVB-Lite standalone ===
This section describes how to quick start a DIVAEVB-Lite system, provided that it is programmed according to DIVELK configuration.
# connect the serial cable, provided with the board, to J6
# connect this cable to PC COM port through a NULL-modem cable (not provided)
# start your favourite terminal software on PC; communication parameters are:
#* baud rate: 115200 Bps
#* data bits: 8
#* stop bits: 1
#* parity: none
# (optional) to connect the system to Ethernet LAN, please plug cable on connector J7
# connect a 12Vcc power supply to J8
Once power has been applied, U-Boot bootloader will be executed and the following messages will be printed on serial console (please note that messages may vary for different U-Boot releases)

These messages are printed by U-Boot, which has a serial console that allows basic interaction with the system.
At the end of its boot sequence, U-Boot prints <code style="board-terminal">DIVA#</code> prompt and waits for user commands.
The default u-boot environment can be printed using the <code style="board-terminal">print</code> command:

== Quick start ==
This section describes how to quick start a DIVA system composed of a DIVA SOM plugged into the DIVAEVB-Lite and then mounted on the Dacu carrier board, provided that it is programmed according to DIVELK configuration. The SD provided with the DIVELK can be used to boot the system, since it contains a bootable partition (mmcblk0p1) and a root file system partition (mmcblk0p2).
