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 peripherals with this image:

• GPIO - they are located in /sys/class/gpio directory. Note that first you have to export GPIOs. For example:
  
  

 # for i in `seq 1 1 230`; do echo $i > /sys/class/gpio/export; done
 will export all available GPIOs
 # echo out > /sys/class/gpio/gpioXX_pxx/direction
 will make the port output
 # echo 1 > /sys/class/gpio/gpioXX_pXX/value
 will make the port output in logical 1

• LCD - 4.3"(480x272), 7"(800x480), 10"(1024x600), 15"(1366x768)
• SATA - with power on/off control
• HDMI - the default HDMI resolution is 720p60(720x1280 - 60 Hz)
• Touch_screen - you need calibrate LCD before using touch screen. Note that if you want to use touch screen in X environment then you have to calibrate it like olimex user,

not like root user because X environment is started like olimex uder. For example type:

 # su olimex
 # sudo ts_calibrate 
 calibrate the touch screen and reboot the board

 there is a simple test for SPI2 in /opt/spidev directory. 
 # ls /opt/spidev
 max6675/
 MOD-SMB380/
 in folder max6675/ there is example related with MOD-TC (link to product)- temperature 
sensor that you have to connect to UEXT1 connector
 # cd max6675
 # ./MAX6675

the last command will read temperature from MOD-TC thermocouple in folder MOD-SMB380 there is example related to MOD-SMB380 (https://www.olimex.com/Products/Modules/Sensors/MOD-SMB380/)3-AXIS ACCELEROMETER BOARD that you have to connect to UEXT1 connector

 # cd MOD-SMB380
 # ./a.out 
 the last command will read temperature and 3-asix accelerometer values

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.

Power supply and consumption

A10-OLinuXino-LIME requires 5V regulated power supply external source. regulated means that the power supply adapter should provide exactly 5V no matter loaded or unloaded (some cheap wallwart adapters are not regulated and under no load their power supply may be higher than 5V although marked as 5V power supply, please measure with voltmeter if your power supply provide 5V as if you connect more than 5V to LIME it will be damaged!!!)

The power jack is standard OLIMEX Power jack.

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:

• 1400mAh
• 3000mAh
• 4400mAh
• 6600mAh

Board dimensions

A10-OLinuXino-LIME basic dimensions in mils: 3305.5 x 2347.0

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

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 download new Android image to the NAND memory of my A10 board?

The 4GB version of the A10-OLinuXino-LIME board comes programmed with Android, which is stored in the NAND flash memory.

The image in the NAND flash can be updated or repaired using the tools found at the following links:

LiveSuit for Windows

LiveSuit for Linux

to the NAND flash; to activate A10 bootloader do as follows: run Livesuit, disconnect the power supply and USB cable of the LIME board, then press and hold down the RECOVERY button, apply power supply, attach USB cable and release the button, install the drivers for the new device discovered by your PC. After the driver installation Livesuit will detect the bootloader and will ask which file to program to the NAND flash.

If there seems to be a problem at some point of the installation, start over.

Note that it is not recommended to have your mini USB connected to an external USB hub. This might cause delays and might distort the signal levels. Always test with the USB connected straight to the USB ports of your computer.

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.
