Safety Precautions
Before getting started, read the following important cautions.
1. Be sure to ground yourself to prevent static charge when installing the internal
components. Use a grounding wrist strap and place all electronic components in any
static-shielded devices. Most electronic components are sensitive to static electrical
charge.
2. Disconnect the power cords from the NA150 before making any installation. Be sure both
the system and the external devices are turned OFF. Sudden surge of power could ruin
sensitive components. Make sure the NA150 is properly grounded.
3. Do not open the system’s top cover. If opening the cover for maintenance is a must, only
a trained technician is allowed to do so. Integrated circuits on computer boards are
sensitive to static electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:
Before handling a board or integrated circuit, touch an unpainted portion of the
system unit chassis for a few seconds. This will help to discharge any static
electricity on your body.
When handling boards and components, wear a wrist-grounding strap, available
from most electronic component stores.

Power LED：
This 2-pin connector (Pin 1, 2) connects an LED indicator to the system power switch on the
case. Pin 2 is assigned as +, and Pin 1 as -. The Power LED lights up when the system is
powered ON.
GPI Pin-header：
This 2-pin connector (Pin 3, 4) connects the GPI signal to the SoC with pin 4, which allows
users to control GPI to be low level.
System Reset Switch：
This 2-pin connector (Pin 5, 6) can be connected to the case-mounted reset switch that
reboots your computer instead of turning OFF the power switch. This method is a better way
to reboot your system for longer life of the system’s power supply.
HDD Activity LED：
This connection is linked to the hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. The 2-pin connector (Pin 7, 8) connects the hard disk drive to
the front panel HDD LED, Pin 7 assigned as -, and Pin 8 is assigned as +.

3.2 Install development environment
Install Ubuntu 12.04 LTS
Install packages for compile kernel and root file system
#sudo apt-get update
#sudo apt-get install libncurses5-dev g++ bison gettext flex texinfo patch git
Download and Untar the Linux BSP “NA150-BSP-1.0.0.tar.gz”
Create a folder and untar the BSP
# mkdir ~/Project/NA150 –p
# tar –zxf NA150-BSP-1.0.0.tar.gz –C ~/Project/NA150
After untar the BSP, you will see following folders
Install cross compiler for NA150
# cd ~/Project/NA150/cross_compiler
# sudo tar –jxf armv7-marvell-linux-gnueabi-hard_i686_64K_Dev_20131002.tar.bz2 –C /opt

3.3 Compile the Linux kernel
Change to kernel source folder
# cd linux-3.2.58
Set the environment variable (To configure the developing environment automatically)
# source setenv.sh
You can modify the setenv.sh by yourself, if you change the path of cross compiler.
Generate .config file
# make na150_defconfig
Modify and compile the Kernel
# make menuconfig
You can modify the kernel by youself as seen below:
After modifying the kernel, use ‘make’ to compile the kernel
# make uImage
The kernel image “uImage” will appear in arch/arm/boot

3.4 Compile root file system
Change to buildroot folder
# cd ~/Project/NA150/buildroot
Set the environment variable (To configure the developing environment automatically)
# source setenv.sh
Generate .config file
# make na150_defconfig
Modify and compile the root file system
# make menuconfig
You can choose packages you want to add in the root file system:
After configuration root file system, use ‘make’ to build root file system
# make
The root file system “rootfs.tar” will in /output/image/

#include<stdio.h>
int main()
{
printf(“hello world\n”);
return 0;
}
Compile the sample program
# arm-marvell-linux-gnueabi-gcc hello.c –o hello
After compiling, enter command “ls” and you can see the ‘hello’ execution file.
How to Put and Run a Sample Program Via USB Flash Drive
From the host, copy ‘hello’ program to USB flash drive.
Attach USB flash drive to NA150.
# mkdir /mnt/usb –p
# mount /dev/sda1 /mnt/usb
# cp /mnt/usb/hello /root
# cd /root
# chmod +x hello
# ./hello
Via TFTP
The Host Development System Installation already has a TFTP server installed.
In the host:
# cp hello /tftpboot
In the target:
# tftp –g –r hello 192.168.0.3 (tftp server IP)
# chmod +x hello
# Run the ‘hello’ program.
#./hello

Connect AP use wpa_supplicant
Configure wpa_supplicant
$ vi example.conf
ctrl_interface=/var/run/wpa_supplicant(you must add this this in the first line)
configure Encryption as disable and no authentication type
network={
ssid="AP_SSID"
key_mgmt=NONE
}
configure Encryption as WEP Open type
network={
ssid=" AP_SSID "
key_mgmt=NONE
auth_alg=OPEN
wep_key0=0123456789
wep_tx_keyidx=0
}
configure Encryption as WEP and shared key as authentication type
network={
ssid=" AP_SSID "
key_mgmt=NONE
auth_alg=SHARED
wep_key0=0123456789
wep_tx_keyidx=0
}
configure Encryption as TKIP and WPA-PSK as authentication type
network={

ssid=" AP_SSID "
pairwise=TKIP
group=TKIP

}
configure Encryption as CCMP and WPA-PSK as authentication type
network={
ssid=" AP_SSID "
pairwise=CCMP
group=CCMP
proto=WPA
key_mgmt=WPA-PSK
psk="12345678"
}
configure encryption as CCMP and WPA2-PSK as authentication type
network={
ssid=" AP_SSID "
pairwise=CCMP
group=CCMP
proto=RSN
key_mgmt=WPA-PSK
psk="12345678"
}
Excute wpa_supplicant to connect to AP
$ wpa_supplicant -BDwext -i wlan0 -c example.conf
If connect success, type command iwconfig, you will see below image
$ iwconfig

$ wpa_cli -i wlan0 terminate
3.8 How to use GPIO to control status LED and push
buttons
NA150 has 2 push buttons and 1 status led can be controlled via GPIO pins
Led control
# echo 64 > /sys/class/gpio/export enable gpio pin
# echo out > /sys/class/gpio/gpio64/direction change direction to out
# echo 0 > / sys/class/gpio/gpio64/value trun on the led
# echo 1 > / sys/class/gpio/gpio64/value trun off the led
Get push button status(SW1 is gpio pin 32, SW2 is gpio pin 38)
# echo 32 > /sys/class/gpio/export enable gpio pin
# cat /sys/class/gpio/gpio32/value
If button is held, the value is 1
If button is released, the value is 0
