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

Linux

The official Debian images are suitable only for microSD card. Information on booting Debian from the NAND might be found at the forum.

 # ./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:

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 do I write the Linux image to a micro SD card to use with my A10 board?

To write a Linux image to an SD card under Windows we use Win32 Disk Imager):

Download Win32 Disk Imager Win32 Disk Imager
Insert card
Start program
Select file
Click "write"

To write a Linux image to an SD card under Linux:

For instance you have an image with the file name of "debian_2g.img". It would be downloaded to the SD card connected to a Linux machine using one of the following commands:

# dd bs=4M oflag=sync if=debian_2g.img of=/dev/sdX

or

# cp debian_2g.img /dev/sdX

where X is the uSD card.

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

Note that we no longer load Android to the NAND memory of the 4GB version of the LIME boards. You can upload Android following the advice below.

The image in the NAND flash can be updated or repaired using a software tool called 'LiveSuit'. Tested version of LiveSuit might be found at the following links:

LiveSuit for Windows

LiveSuit for Linux

There might be newer versions available.

LiveSuit is used to send the official Android images to the NAND flash memory of the board. To activate the A10 bootloader do as follows: run LiveSuit; disconnect the power supply and USB cable from the LIME board; then press and hold down the RECOVERY button; apply power supply; attach USB cable; release the RECOVERY button; install the drivers for the new device discovered by your PC - manually point to the folder where LiveSuit got installed. 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 do I write the official Android image to a micro SD card for my A10 board?

There might be different Android images available for an SD card. They can be downloaded above A10-OLinuXino-LIME#Android. Note that Android display configuration settings are edited in the script.bin file (it has to be converter to fex and edited according to the fex guide at linux sunxi's article; then converted back to script.bin and written in the image). To write the images on the SD card you will need PhoenixSuit and to follow these steps:

• Install and run PhoenixSuit (can be found here: download from google drive)

• Go to the firmware tab of the program and point to a valid Android image (note that the images are compressed and you have to extract them to .img files to be able write them with PhoenixSuit)

• Disconnect the power supply and USB cable from the A10 board. Put an SD card in micro SD holder. We recommend 4GB class 10 card.

• Press and hold RECOVERY button, apply power supply (6-16)V, release RECOVERY button.

• Connect USB cable to the mini USB connector.

• You will be asked for drivers for the boot-loader. Navigate to the folder where you extracted the PhoenixSuit and install the drivers from the respective executable (or manually point the installer to the drivers folder in the PhoenixSuit installation path).

• PhoenixSuit will detect the board and would ask for the method of writing the image. Choose method of writing the image and confirm your wish to write the image.

• Wait till upgrade succeeds

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.

Important: When Android runs for very first time it takes several minutes to initialize all files and buffers please do not cut the power supply during this process! Also when fresh image is installed fast boot may be disabled, which means that when you apply power supply after few seconds Android will go in sleep mode and you have to press POWER button to start it, you can change to fast boot when you power off there is dialog box asking you if you want next boot to be fast boot, you have to check this box before you power off. Also note that you must do touch screen calibration when you run Android for very first time which might require a mouse.

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.
