=== DivaEVB-Lite ===
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:

== Build system ==
</pre>
Next time the system boots, U-Boot will wait for three seconds (to stop the wait just press any key in the console) before executing the commands stored in the bootcmd variable. This time can be changed by setting the bootdelay variable. Generally speaking the whole boot process can be further and heavily customized. For more details please refer to the doc/README.autoboot file in the U-Boot sources.
