3. Setup
3.1 Connecting the Debug Port to PC
During development, it is a good idea to connect using the debug port.
There are different port location between SBC2000/NSD2105 and other 2100 series.
SBC2000/NSD2105
Find the debug port on SBC2000/NSD2105
C220 debug board and the cable on it:

Connect the cable on C220 debug board to the debug port of SBC2000/NSD2105
Connect a RS232 IDC cable to C220 debug board

Other 2100 series (including SBC2100, NSD2107/10/15/22, EC2107/10)
Find the debug port on SBC2100 series board
Connect a RS232 IDC cable to the debug port

Connect to PC
Turn on the PC, run the terminal program, and open the COM port. We use TeraTerm.
You can find this tool and the user guide on our wiki page online.
Console / Debug Port Connection Diagram
UART1 is dedicated as the debug port. UART1 default settings are Baud Rate
115200, 8 data bits, no parity, 1 stop bit and no flow control.
A DB9 null modem cable (or adapter) is required when you want to connect UART1
to a PC with terminal emulation software such as TeraTerm.
DB9 null modem cable
For SBC2100
For SBC2000/NSD2105 only

Pin Assignment: RS232 IDC Cable and Null Modem Adapter
We prefer to use this kind of adapter if your DB9 cable is straight through cable. (Not
cross-connected)

3.2 Start Running
After connecting to the debug port, please power on the device to start.
1. Before logging into the system, you can enter into the U-Boot environment to
check some variables. After powering on, quickly hit the Enter key within 3
seconds when you see the message below.
Hit any key to stop autoboot: 3
2. Type ‘?’or ‘help’ to get all U-Boot commands and more details.
3. Type printev on the U-Boot shell to see the current environmental variables
> printenv
4. Use the command below to modify an environment variable.
> setenv variable 'string value'
If you need to change your output display, do the following command to set the
variable “panel”; otherwise, we do not recommend you doing this step.
Android
//HDMI (1920 x 1080)
> setenv panel 'video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 video=mxcfb1:off
cea'
//7” LCD-PT (800 x 480) with RTP
> setenv panel 'video=mxcfb0:dev=lcd,LCD-WVGA,if=RGB24,bpp=32 video=mxcfb1:off'
//7” LCD-AWT (800 x 480) with RTP
> setenv panel 'video=mxcfb0:dev=lcd,AWT-WVGA,if=RGB24,bpp=32 video=mxcfb1:off'
Ubuntu
//HDMI (1920 x 1080)
> setenv panel 'video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:off'

//7” LCD-AWT (800 x 480) with RTP
> setenv panel 'video=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB24 video=mxcfb1:off'
For other LCD / LVDS panels we support, please contact to our sales in order to
get right string value.
5. Use the command saveenv to save the environment variables that you have
modified. If not saved, then any changes to the variables will not persist after a
restart.

3.3 Connecting to the PC (for Android 4.2)
For Android systems, connect to a Windows PC by following the steps below:


Install Android SDK


Connect to PC with USB OTG cable


Install USB driver
3.3.1 Installing the Android SDK
This chapter is intended for developers to quickly setup an EC/NSD/SBC and know
how to launch EC/NSD/SBC demo applications from a host PC via a USB interface.
The host PC requires a Windows system (for example Windows XP or 7) and at least
a few gigabytes free disk space. The first time you launch a demo app from the host
PC, you will have to install a driver into the host PC.
Follow the steps below to install the driver and make the hardware connection:
1. Insert the software DVD into the host PC and find theAndroid SDK folder. Copy to
the host PC in a folder named <SDK>
2. Add the <SDK> folders to the path environment variable of the host PC:
;<SDK>\tools;<SDK>\platform-tools
3. The following figures illustrate the steps to add a path on a Windows 7 PC:
Computer > Properties > Advanced system settings > Environment
Variables… > Path > Edit…

3.3.2 Connecting to the PC with a USB OTG cable
Connect the power adapter to an EC21/NSD21/SBC21 power jack and plug the
power adapter to an AC outlet.
Wait for the EC21/NSD21/SBC21 to boot up and show a standard desktop on the
LCD screen. Astandard Android desktop is similar to the following figure.
Connect a USB cable to EC21/NSD21/SBC21 mini-USB connector.

3.3.3 Installing the USB Driver (Android ADB Interface)
When first connected, the host PC will prompt you about detecting an unknown USB
device and ask you to install a driver. Choose to install software from a specific
location.
Find the USB driver in the software DVD and copy it to the host PC. Add the path of
Android USB driver as the search path for the wizard:
;D:\android-sdk-windows\extras\google\usb_driver
After the driver is successfully installed, you will find an “Android Phone”with the
Android ADB interface in Device Manager.
