This section describes how to quick start a DivaEVB-Lite system, provided that it is programmed according to DIVELK configuration.
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:

=== DivaEVB-Lite plugged on Dacu ===
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 and the following messages will be printed on serial console (please note that messages may vary for different U-Boot releases)
