Official Images from OLIMEX
The file for download xxxx.7z is an archive of xxx.img file. So in order to write the image on SD card you have to unzip xxx.7z file and:
- For Windows:
Use 7zip and then use Win32DiskImager.exe (http://sourceforge.net/projects/win32diskimager/) for image writing
- For Linux
Use p7zip package. If you have no installed 7zip then type
#apt-get install p7zip
Copy a10_Lime_debian_second_release.7z file in your directory and unzip it with
#7za e a10_Lime_debian_second_release.7z
The output should be a new 4GB file named a10_Lime_debian_second_release.img Put 4GB SD card in your card reader and type
# ls /dev/sd
Then press two times <TAB> you will see a list of your sd devices like sda sdb sdc note that some of these devices may be your hard disk so make sure you know which one is your sd card before you proceed as you can damage your HDD if you choose the wrong sd-device. You can do this by unplugging your sd card reader and identify which "sd" devices remove from the list. Once you know which device is your sdcard like sda use this text instead of the sdX name in the references below:
#dd if=a10_Lime_debian_second_release.img of=/dev/sdX

Tested board peripherials with this image:
- GPIO - located at /sys/class/gpio
- LCD - supported are A13-LCD4.3TS, A13-LCD7TS, A13-LCD10TS
Touch_screen - you need calibrate LCD touch screen usi it. Note that by default the X environment does not start like root user. In our case the X starts with user named olimex Therefore if you want to use the touch screen in X environment then you have to run calibrate procedure like olimex user. For example type:
#su olimex
enter the olimex password:olimex
#sudo ts_calibrate
calibrate the touch screen and reboot the board
#sudo reboot
- SATA - works including power on/off control
- HDMI - the default HDMI resolution is 720p60(1280x720-60 Hz)

- USB_HOST_down - works as Low/Full/High USB host
- mico_SD_card - allow Linux boot
- secondary SD-MMC card - with card present detector
ETHERNET - 100Mb. Note that by default the board is set with DHCP. You can change it in /etc/network/interfaces file*I2C2(100KHz) - /dev/i2c-2
- I2C1(100KHz) - /dev/i2c-1
- UART4 - /dev/ttyS1
Note: the A10-Debian card which we have in our web store contains the same image on 4GB Class10 fast micro SDcard, if you want to use this image please use card of Class10 speed or the performance of Linux will be very slow.
Note: in the previous Debian releases the Ethernet was auto-detected and initialized during boot BUT this was causing big delays in the start-up of the board if you didn't want to use Ethernet or if there wasn't Ethernet cable connected.
You can enable it by following these two steps:
1. To check under what name the LAN is associated write "ifconfig –a"
2. If, for example, it is under eth0 name, then write: "dhclient eth0"
This should enable the Ethernet and then SSH would also be available.
Android
Android 4.1.1 NAND image will be available soon

A template that might be used to create custom shields or own adapters might be downloaded for Eagle or KiCad at the GitHub here: shield template
Power supply and consumption
A10-OLinuXino-LIME can be powered from three sources:
- +5VDC voltage applied PWR jack
- +3.7V from LiPo re-chargable battery connected to LiPo board connector
- +5V applied to USB-OTG connector
Power consumption is as follows:
- LiPo 3.7V power battery: 1.2W
- +5VDC input power: 1.3W
Comparison table of power consumption might be found at the following link.
LiPo battery allow backup power supply when main power is interrupted. A10-OLinuXino-LIME have power managment IC which charge the battery when main power is present, when power is interrupted the LiPo battery automatically provide backup power supply. Step-up converter prvide 5V for the USB peripherials too. For LiPo batteries we recommend these:
Board dimensions
A10-OLinuXino-LIME basic dimensions in mils: 3305.5 x 2347.0
Some additional measures might be seen in the image here: link
CAD files
A10-OLinuXino-LIME is Open Source Hardware, CAD files are available at GitHub
The CAD product used to design OLinuXino is Eagle and you can download evaluation free version from their web.
Board Layout
Software
Python
[pyA10 is Python library for access to A10-OLinuXino-LIME GPIOs, I2C, SPI]
Use:
#!/usr/bin/env python import A10_GPIO as GPIO #init module GPIO.init() #configure module GPIO.setcfg(GPIO.PIN#, GPIO.OUTPUT) GPIO.setcfg(GPIO.PIN#, GPIO.INPUT) #read the current GPIO configuration config = GPIO.getcfg(GPIO.PIN#) #set GPIO high GPIO.output(GPIO.PIN#, GPIO.HIGH) #set GPIO low GPIO.output(GPIO.PIN#, GPIO.LOW) #read input state = GPIO.input(GPIO.PIN#) #cleanup GPIO.cleanup()
GPIO under Linux
GPIOs are located in /sys/class/gpio directory. Note that first you have to export GPIOs. For example:
add gpioPH2
root@A10:~# echo 20 > /sys/class/gpio/export
make PH2 output
root@A10:~# echo out > //sys/class/gpio/gpio20_ph2/direction
turn on onboard LED(connected to PH2)
root@A10:~# echo 1 > /sys/class/gpio/gpio20_ph2/value
turn off onboard LED(connected to PH2)
root@A10:~# echo 0 > /sys/class/gpio/gpio20_ph2/value
Full list with supported GPIOs is:

How To?
How to generate boot-able SD-card Debian Linux image for A10-OLinuXino-LIME?
Follow our blog post with step by step instructions
Note that Linux-Sunxi Kernel is a work-in-progress, this means you can try the current stage/sunxi-3.4 branch but if something is broken and doesn't work just revert to the git tags we give in the blog and they should work for sure
Sunxi u-boot loader The linux-sunxi git page contains a lot of sources for all Olimex Allwinner boards.
How to change HDMI, VGA and LCD resolutions?
The default SD card setup is made with settings for HDMI 720p/60Hz. If you want to change to some other LCD, VGA or HDMI resolution then you have to start change_display.sh script file in /root directory.
Type:
./change_display*
or
./change_display_a10_lime.sh
and press "Enter".
Then choose the resolution and the interface(LCD, HDMI). Note that the selection of a specific resolution is done by navigating with the arrow keys and pressing "space" button. Make sure the asterisk marks your selection properly.
The supported resolutions are:
For LCD:
- 1. 4.3" (480x272)
- 2. 7" (800x480)
- 3. 10" (1024x600)
- 4. 15.6" (1366x768)
Important: initially the boards are calibrated for a specific display. If you re-write the image (no matter whether the SD card or the NAND memory) you would need to use a mouse to calibrate the display initially. It might be impossible to calibrate it via touching the display.
For HDMI:
- 0. 480i
- 1. 576i
- 2. 480p
- 3. 576p
- 4. 720p50
- 5. 720p60
- 6. 1080i50
- 7. 1080i60
- 8. 1080p24
- 9. 1080p50
- 10. 1080p60
For VGA: (note that the VGA signals are routed to custom 6 pin connector and you need from adapter to standard VGA connector)
- 0. 1680x1050
- 1. 1440x900
- 2. 1360x768
- 3. 1280x1024
- 4. 1024x768
- 5. 800x600
- 6. 640x480
- 7. 1920x1080
- 8. 1280x720
How to detect and enable the Ethernet controller (if it is disabled by default)?
Note: in the previous Debian releases the Ethernet was auto-detected and initialized during boot BUT this was causing big delays in the start-up of the board if you didn't want to use Ethernet or if there wasn't Ethernet cable connected.
You can enable it by following these two steps:
1. To check under what name the LAN is associated write "ifconfig –a"
2. If, for example, it is under eth0 name, then write: "dhclient eth0"
This should enable the Ethernet and then SSH would also be available.
