Android

A10S Android NAND image with HDMI

• Android_version - 4.0.3
• Baseband version - 1.2
• Kernel version 3.0.8+

A10S-OLinuXino-MICRO Android SD-CARD image with HDMI

You have to unrar the file and write the image on 4GB sd card. We recommend you to use a class 10 card. You can use dd (under linux) or Win32DiskImager.exe (under Windows) for the image writing.

• Android_version - 4.0.3
• Baseband version - 1.2
• Kernel version 3.0.8+

Changing screen resolution in the SD card image:

The default screen resolution of A10s android SD card image is HDMI. If you want to change to LCD 10''(1024x600) or LCD7''(800x480) you have to replace the default script.bin file in the main SD card card partition. For this purpose put the SD card in a card reader on Linux machine (it might not work under Windows due to the Android file system format), mount the SD card, find script.bin file(usually it is located in the ../Volume partition) and replace it with the script.bin file from the corresponding directory. The scripts might be also downloaded from here: A10s Android SD scripts

The available directories are:

script_a10s_android_LCD_800x480_TS_GPIO - contains script for A13-LCD7-TS script_a10s_android_LCD_1024x600_TS_GPIO - contains script for A13-LCD10TS script_a10s_android_HDMI_GPIO - contains script for the default HDMI resolution

Note that you have to calibrate the touch screen with running Calibration application on Android Desktop. You would need a USB mouse to run the Calibration because the touch screen would still carry the old calibration settings.

The LCD output will be active only if the board boots without HDMI cable connected.

This method of changing the default display setting will NOT work with the NAND Android!

Python

pyA10S is Python library for access to A10S-OLinuXino-MICRO GPIOs, I2C, SPI

Use:

   #!/usr/bin/env python
   
   import A10S_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. the full list of A10S GPIOs is:

   root@A20:~# ls /sys/class/gpio/
   export       gpio14_pc17  gpio19_pe5  gpio23_pe9   gpio4_pb11  gpio9_pb3
   gpio10_pb4   gpio15_pe1   gpio1_pb14  gpio24_pe10  gpio5_pb5   gpiochip1
   gpio11_pc3   gpio16_pe2   gpio20_pe6  gpio25_pe11  gpio6_pb6   unexport
   gpio12_pc7   gpio17_pe3   gpio21_pe7  gpio2_pb13   gpio7_pb7
   gpio13_pc16  gpio18_pe4   gpio22_pe8  gpio3_pb12   gpio8_pb8

Example how to toggle onboard LED. The LED is connected to PE3.

make PE3(LED) output

   root@A10s:/sys/class/gpio/gpio17_pe3# echo out > direction

turn on onboard LED(connected to PE3)

   root@A10s:/sys/class/gpio/gpio17_pe3# echo 1 > value

turn off onboard LED(connected to PE3)

   root@A10s:/sys/class/gpio/gpio17_pe3# echo 0 > value

How to generate SD Debian Linux image with Kernel 3.4

How to Build SD card Debian Linux image with Linux Kernel 3.4

How do I write the Linux image to a micro SD card to use with my A10S 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_4g.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_4g.img of=/dev/sdX

or

• # cp debian_4g.img /dev/sdX

where X is the uSD card.

How to change HDMI and LCD resolutions in the latest Debian image?

The default SD card setup is made with settings for HDMI 720p/60Hz. If you want to change to some other LCD or HDMI resolution then you have to start change_display.sh script file in /root directory.

Type:

   # ./change_display.sh

and choose the resolution and the interface(LCD, HDMI or VGA). 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)

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

Note that you have to calibrate touch screen after changing LCD resolution in the script.bin type:

   root@A10s:~# ts_calibrate

and calibrate the LCD touch screen you can test the calibration using ts_test.

   root@A10s:~# ts_test

and finaly you hsve to reboot the board in order to use the touch screen in X environment.

How to flash new Android image to the NAND memory of my A10s board?

To repair the image on the NAND re-upload it following these steps:

1. Download, install and start LiveSuit (download location might be found above the article)

2. Hold down “BOOT/REC” button on the board

3. Connect the board to the computer via the mini connector of the USB-OTG

5. Release “BOOT/REC” button

6. You will be asked for drivers for the bootloader. Navigate to the folder where you extracted the LiveSuit and install the drivers from the respective executables (or manually point the installer to the drivers folder in the LiveSuit installation path).

7. Choose the image you have prepared or downloaded

8. Update and don't disconnect the board until the LiveSuit program confirms the update is complete
