Hardware setup

This section describes how to quick start the SBCX 
The system is programmed to automatically boot Linux at power up, 
loading the bootloaded, the kernel image and the root file system from 
the internal flash memory.
To start the system:

●

connect the 12Vcc power supply to JP2 on the DACU board

●

(optional) connect the DB9 adapter bracket to the J22 connector on the 
SBCX and connect the DB9 connector to the PC COM port through a 
NULL-modem cable (not provided)

●

connect the ethernet cable from your LAN hub/switch to the J16 RJ45 
connector

●

connect to the SBCX through SSH, using the following parameters:

◾

ip address: 192.168.1.1

◾

username: root

◾

empty password

6.3

First boot

Once power has been applied, U-Boot bootloader will be executed and 
the debug messages will be printed on the serial console. U-Boot 
automatically runs the 

autoboot

 macro, that loads the kernel and 

launches it with the options for mounting the root file system from the 
flash memory. At the end of the boot process, a demo application is 
launched and you can interact with the system using the touchscreen.
Moreover, the Linux shell is available on the serial console. Lastly, both 
telnet and ssh services are available to connect to the system through 
the network.
Please refer to Appendix 9.3 for an example of the boot messages.

6.3.1

Accessing the serial console

1.

connect the DB9 adapter bracket to the J22 connector on the 
SBCX board

2.

connect a serial cable between DB9 connector and PC COM 
port through a NULL-modem cable (not provided)
