Introduction to the chapter Thank you for choosing the OLinuXino single board computer from Olimex! This document provides a user’s guide for the Olimex OLinuXino board. As an overview, this chapter gives the scope of this document and lists the board’s features. The document’s organization is then detailed. The OLinuXino development board enables code development of applications running on the microcontroller A13, manufactured by Allwinner Technology from China. OLinuXino is an open-source, open-hardware project and all documentation is available to the customer. 1.1 Features The board has the following set of features: • • • • • • • • • • • • • • • A13 Cortex A8 processor at 1GHz, 3D Mali400 GPU 512 MB RAM 6-16VDC input power supply, noise immune design 3 + 1 USB Host, 3 available for users 1 for (only in A13-OLinuXino-WIFI) WIFI RTL8188CU 802.11n 150Mbit module on board 1 USB OTG which can power the board SD-card connector for booting the Linux image (only in A13-OLinuXino-WIFI) 8GB NAND flash (older revisions had 4GB NAND flash) VGA video output – 800×600 resolution LCD signals available on connector so you still can use LCD if you disable VGA/HDMI Audio Output Microphone input RTC PCF8536 on board for real time clock and alarms 5 Keys on board for android navigation UEXT connector for connecting additional UEXT modules like Zigbee, Bluetooth, Relays, etc GPIO connector with 68/74 pins and these signals: 17 for adding NAND flash; 22 for connecting LCDs; 20+4 including 8 GPIOs which can be input, output, interrupt sources; 3x I2C; 2x UARTs; SDIO2 for connectinf SDcards and modules; 5 system pins: +5V, +3.3V, GND, RESET, NMI Page 5 of 39 OLIMEX© 2017 A13-OLinuXino user's manual 1.2 Target market and purpose of the board The boards from the OLinuXino family are easy to setup and powerful. They are suitable for embedded programming enthusiasts, Linux and Android gadget fans and also professionals (since its low cost makes it very good solution for application orientated embedded systems). The main usage of the board is software embedded development without the urge of understanding perfectly the hardware. The strong points of the boards are the processor speed, the mobility of the board and the low ratio price to productivity. Customers have full access to the technical documentation of the board. The software is released under General Purpose License and the board is considered open-hardware. 1.3 Board variants Olimex manufactures three types of boards with the same A13 processor – A13-OLinuXino, A13OLinuXino-MICRO, and A13-SOM. Each of these designs has a different goal and each design might have several different variants (typically each of these designs has a variant with NAND memory). The base model has two flavors: A13-OLinuXino and A13-OLinuXino-WIFI. The first one is the base model that goes without any operating system image on board, while the second has two additional components – a WIFI module on the board and NAND memory with stored Android image. The A13-OLinuXino-Micro differs from the base A13-OLinuXino by having only 1 USB host, 1 USB OTG, no power connector, no NAND memory, no WIFI, no audio out connector, less buttons. If you are looking for an A13 board with tiny dimensions and suitable for implementing in own designs then refer to A13-SOM board – it has tiny dimensions. There are more powerful A10 and A20 designs that Olimex manufactures nowadays. Boards like A20-OLinuXino-LIME; A20-OLinuXino-MICRO and A20-OLinuXino-LIME2 are generally faster and capable of much better video output.

Introduction to the chapter This section helps you set up the OLinuXino development board for the first time. Please consider first the electrostatic warning to avoid damaging the board, then discover the hardware and software required to operate the board. The procedure to power up the board is given, and a description of the default board behavior is detailed. 2.1 Electrostatic warning OLinuXino is shipped in a protective anti-static package. The board must not be exposed to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling the board. Avoid touching the component pins or any other metallic element. 2.2 Requirements In order to set up the OLinuXino optimally, the following items are required: - Power supply unit which is capable of providing voltage in the (6V-16V) DC range, minimum 6W are required to ensure smooth operation (6V @ 1A or 16V @ 0.4A) - Output medium – USB-to-serial cable (to connect to a personal computer with serial terminal software), or LCD (preferably with touchscreen panel) display for the LCD_CON, or TV monitor with RGB port Additional items include: - USB keyboard – for convenience with text input - USB-SERIAL-CABLE-F – for serial communication with UART1 connector - USB-MINI-CABLE – for connecting with the USB OTG and being able to update the Android (if your board has NAND memory) - Wireless internet connectivity or USB modem – for browser access and access to the Android market Some of the suggested items can be purchased by Olimex, for instance: SY0612E – power supply adapter 12V/0.5A for A13-OLinuXino USB-SERIAL-CABLE-F – USB serial console cable female USB-MINI-CABLE – standard USB type A to USB type mini cable Page 8 of 39 OLIMEX© 2017 A13-OLinuXino user's manual The recommended LCD display for the board is 7 inch with an optional touch screen panels suitable for the board: Display name LCD-OLinuXino-7 Size of display in inches 7 Native resolution in pixels 800×480 Official Debian image support Yes Official Link to product Android image page support Yes Product page LCD-OLinuXino-7TS 7 800×480 Yes Yes Product page Note that if you wish to use one of the LCD displays mentioned above you need to upload different Android image – configured for 480×800 screen resolution. 2.3 Powering the board There are three possible ways of powering A13-OLinuXino – via external supply using the power jack, via a battery using the battery connector or via the USB OTG connector. Depending on your preferred way of powering A13-OLinuXino you might need additional hardware. The preferred way of powering board is via the PWR jack with 6Vdc to 16Vdc with a power of 6W (e.g. 6Vx1A to 16Vx0.4A). This will make the board fully powered and able to power all the peripherals connected to it. When powered by the typical 3.7V Lithium-polymer battery the board will be fully functional and you will be able to operate with most of the peripherals. However when using all three USB-A connectors and an LCD connected to the LCD_con it might cause flickering and not sufficient power. If you suspect the power is not enough for the peripherals you have connected use the PWR jack. The board can be also powered by the USB OTG connector (mini USB standard) but the voltage provided is not enough to power a possible LCD connected to the LCD_con. However, this power option is capable of driving the board when using external display connected to the VGA connector. If you have a standard LCD display connected to LCD_con, Android and WIFI running the typical consumption is between 150mA and 350mA depending on the current load. While the board is in stand-by mode it consumes a minimum of 60mA. All the three approximate values above were taken when I applied 12V to the board. Important! Avoid disconnecting the power supply while Android or Linux is running, since that might corrupt the operating system and you will need to install the OS again (for Android install instructions check chapter 2.6. Use the PWR_BUT before disconnecting the supply. If the board has entered power-down state you can bring it back without restart using the PWR_BUT. Page 9 of 39 OLIMEX© 2017 A13-OLinuXino user's manual For the European customers we sell a power supply adapter 12V/0.5A – SY0612E. We also sell USB OTG to USB type A cables if you lack such. 2.4 Prebuilt software Note that the A13-OLinuXino-WIFI board no longer comes with Android loaded in the NAND memory! Please follow the advice in this chapter to upload it to the NAND. How we have installed the software? We have configured an Android image with settings suitable for A13-OLinuXino. Then using LiveSuit or PhoenixSuit tools we uploaded the image to the board. To activate A13 bootloader do as follows: run Livesuit, disconnect the power supply and USB cable, then press HOME button, apply power supply, attach USB cable and release the button, Livesuit will detect the bootloader and will ask which file to program to the NAND flash. The image will be available for users to try and tweak the settings. You can find and image with the view of the progress window in LiveSuit: Download links to all available images (and tools needed) can be found at the A13-OLinuXino wiki page: https://www.olimex.com/wiki/A13-OLinuXino. Helpful information about the Android and Linux images can be found at the OLIMEX forums. Page 10 of 39 OLIMEX© 2017 A13-OLinuXino user's manual 2.5 Button functions in Android The following buttons represent functions in the Android: PWR_BUT – used to wake the board from stand-by HOME – shows the home screen; note that HOME is also used to enter bootloader mode for firmware update ENTER – to select a choice MENU – brings up the main menu VOL+ – increases the volume VOL- – lowers the volume For more information on the button functions check the Android documentation. Note that RESET button will perform a hardware reset of the board, not controlled by the OS. 2.6 How we configured the Android image This is a detailed explanation of how we got to tweak the Android image configuration files. It is worth mentioning that we used Ubuntu with Linux Kernel 3.2 for the steps below. 2.6.1. Getting the Android SDK tools Download the Android SDK tools for Linux from: http://developer.android.com/sdk/index.html Note that you have to click “Other platforms” and get the one for Linux. Then you extract it: tar zxfv android-sdk_r20.0.3-linux.tgz Note that the above line would vary depending on the version you have downloaded (by the time of writing 20.0.3 was the latest one). 2.6.2. Adding information for the board in the Linux Create the following file: .../etc/udev/rules.d/70-android.rules and add the following line inside: SUBSYSTEM=="usb_device", SYSFS{idVendor}=="18d1", MODE="0666" then we save the file and change its properties with chmod +x 70-android.rules and reboot the computer. Page 11 of 39 OLIMEX© 2017 A13-OLinuXino user's manual 2.6.3. Installing the SDK tools Navigate to the folder where we extracted the tools (folder tools) in point 1 and start it: ./android From the check boxes select to install Android SDK Tools, Android SDK Platform Tools and Android 4.0 API 2.6.4. Connecting the A13-OLinuXino Power the A13-OLINUXINO. Now connect the miniUSB to the board and wait a bit for the USB to enumerate. After the tools are installed we navigate to “platform-tools” folder located in the directory of the tools (where we extracted in point 1), then we enter: ./adb devices which will show us the list of the available devices. The output should would like: List of devices attached 20080411 device However if we get “bash: ./adb: No such file or directory“- we have to check if the ia32-libs are installed if not, we install them with: apt-get install ia32-libs If again the device is not listed we try to stop and run the server again with the following (we have to be logged as root!): cd /home/android-sdk/platform-tools/ ./adb kill-server ./adb start-server Exit the root and enter the shell of the device ./adb shell We then create mounting point for the NAND memory: mkdir /sdcard/nanda Page 12 of 39 OLIMEX© 2017 A13-OLinuXino user's manual and finally we mount the NAND: mount -t vfat /dev/block/nanda /sdcard/nanda Note: NAND mounting should be performed every time the device is restarted! 2.6.5. Downloading the default config file and script tool Get the default 800×600 config file from: https://docs.google.com/open?id=0B7WHuNCASY8caVRlV29GdUVPX3M Open a new console (which will be used to edit the config file) - - then we download the following script: https://docs.google.com/file/d/0B_DiNI-XElrMjQ4MmJhZGEtNmU1NS00MzllLWIzOWMtMzExODc5NTRkMGQ3/edit We save both of the above files (both should be in the same folder) Then we execute from the console: chmod +x script 2.6.6. Applying the script and uploading the confing After we have edited the file as we win we do: ./script A13_config_600x800.fex_ok and then we push it on the device path_to_android_sdk/android-sdk-linux/platform-tools/adb push A13_config_600x800.fexbin /sdcard/nanda/script.bin 2.6.7. Restarting the A13-OLinuXino We go to the shell of the A13-OLinuXino board and reboot Page 13 of 39 OLIMEX© 2017 A13-OLinuXino user's manual 2.7 GPIO under Debian You can read data from a given GPIO port. The logical ranges are usually as follows: 0V-1V for LOW (or 0) 2.4V-3.3V for HIGH (or 1) All voltages are measured against ground (GND). If the input signal is to high, you will at least destroy the port! The algorithms for writing a value to a GPIO port and reading such a value are pretty similar. The usage of GPIO ports follows the algorithm (we would use GPIO #49 for demonstration purposes): 1. Export GPIO 49: echo 49 > /sys/class/gpio/export Note that you can export GPIOs in range with: for i in `seq 1 1 230`; do echo $i > /sys/class/gpio/export; done 2. Set input/output GPIO 49 2.1 Set input: echo "in" > /sys/class/gpio/gpio49_ph9/direction 2.2 Set output: echo "out" > /sys/class/gpio/gpio49_ph9/direction 3. Set value or read value GPIO 49 3.1 Set value: echo 0 > /sys/class/gpio/gpio49_ph9/value echo 1 > /sys/class/gpio/gpio49_ph9/value 3.2 Read input: cat /sys/class/gpio/gpio49_ph9/value Page 14 of 39 OLIMEX© 2017 A13-OLinuXino user's manual 4. Unexport GPIO 49 when finished echo 49 > /sys/class/gpio/unexport A very good document on GPIO usage might be found here: http://www.py6zgp.com/download/A20-GPIO.pdf – the document was created by Dr. Guido Pelz. Instructions on how to edit board configurations might be found here: https://www.olimex.com/wiki/How_to_edit_board_configurations_and_definitions_in_the_official_ Debian_Linux Information on how to use the WIFI, Ethernet or GPIOs is available at the following web address: https://www.olimex.com/wiki/Configuration_of_hardware_in_the_debian_image 2.8 I2C and SPI under Debian I2C and SPI are both supported in the latest Debian releases. There is respective kernel support for both. There is a python module called pyA13 might be found here: https://pypi.python.org/pypi/pyA13 At the same web address you would also find a set of examples on how module is used. 2.9 Software support We maintain Linux and Android images for SD card which might be downloaded for free and modified as the user wishes. The latest images and updates are featured at the wiki article of the device: https://www.olimex.com/wiki/A13-OLinuXino. We usually try to provide details on how to build the Linux and the Android images at our wordpress page: http://olimex.wordpress.com/. Another useful place is the Olimex forums where a lot of people share their experience and advice: https://www.olimex.com/forum/ Additional Android and Linux support and features are added overtime. The Linux support is a work-in-progress and you should not expect full Linux support after the initial volume of such boards have become available on the market. If you are in a hurry consider the older OLinuXino designs (which have almost everything supported, have examples available and so on). You are more than welcome to send or share your suggestions and ideas at our e-mail, the public forums or irc channel. We would attempt to help in almost every case. We listen to the feedback and if the majority of users suggest a software change or update we try to implement such. Customer feedback is very important for the overall state of the software support. However, do not expect full Linux or Android software support. We can share our experience. We can give you full details for things we have tried. We can point you to a resource or a guide. We can give you general directions to solving a specific problem or Page 15 of 39 OLIMEX© 2017 A13-OLinuXino user's manual places to look for more information. However, we won’t install a piece of software for you or write custom program for you. We won't provide a specific software solution to a specific software problem.

Page 20 of 39 OLIMEX© 2017 A13-OLinuXino user's manual CHAPTER 5: CONTROL CIRCUITY 5. Introduction to the chapter Here you can find information about reset circuit and quartz crystals locations, the power supply circuit is discussed. 5.1 Reset The reset line is handled by the AXP209 (which is an enhanced single cell Li-battery and power system management IC that goes together with the Allwinner processor) and goes to processor pin 159 via R4(47k). The reset circuit is connected to button RESET, which means pressing RESET would perform a hardware reset on the board. 5.2 Clocks 24 MHz quartz crystal Q1 is connected to pins 91 and 92 of the A13 processor. 12 MHz quartz crystal Q2 is found at pins 6 and 7 of the GL850G (the USB controller). 32 768 kHz (RTC clock) quartz crystal Q3 is found connected to pins 1 and 2 of the RTC_MODULE (PCF8563T) 5.3 Power supply circuit The power supply is handled mainly by AXP209 power management system, an Allwinner chip that goes together with the A13 processor. The power supply circuit of A13-OLinuXino allows flexible input supply from 6V to 16V. The minimum amperage suggested is 1A, and this threshold would rise if using all the three USB-HOSTs, a lot of GPIOs and LCD_con. The board can also be powered by 3.7V Li-Po battery retaining its functionality or by USB (limiting the use of peripherals. Important! Avoid disconnecting the power supply while Android or Linux is running, since that might corrupt the NAN memory (and the operating system files) and you will need to install the OS again (for Android install instructions check chapter 2.6. Hold the PWR_BUT and then navigate to shut down before disconnecting the supply. Page 21 of 39 OLIMEX© 2017 A13-OLinuXino user's manual CHAPTER 6: CONNECTORS AND PINOUT 6. Introduction to the chapter In this chapter are presented the connectors that can be found on the board all together with their pinout and notes about them. Jumpers functions are described. Notes and info on specific peripherals are presented. Notes regarding the interfaces are given. 6.1 Communication with the A13 The chip has a built-in bootloader so everything you need for debugging is an USB cable. However there is a second option which is the male UART1 connector capable of delivering some information on the COM port of your computer. You can use USB-SERIAL-CABLE-F with the UART1 interface allowing you to connect to an USB port. 6.1.1 USB communication The main way of communicating with the firmware of A13-OLinuXino is via the USB-OTG connector. You will also need a software tool “LiveSuit” and a newer firmware image if you wish to upgrade the firmware. The “LiveSuit” tool may be downloaded from the A13 wiki page. The simple steps for upgrading the firmware via the bootloader are: 1. Start LiveSuit 2. Disconnect power supply cable and USB cable from A13-OLinuXino 3. Hold “Home” button 4. Connect the board to the power supply and the computer via the USB-OTG 5. Release “Home” button 6. You will be asked for drivers, point the installer to the LiveSuit folder which contains drivers for the bootloader 7. Choose the image in the LiveSuit 8. Update and don't disconnect the board The three USB type A hosts are wired to a USB-controller GL850G which is an advanced version hub solution fully complying with Universal Serial Bus Specification Revision 2.0. GL850G has proven compatibility, lower power consumption figure and better cost structure above all USB2.0 hub solutions worldwide.

You can use our USB-SERIALCABLE-F for debugging via the UART1 or UART0. Note that in both cases the connectors are named at the bottom of the board. Depending on the revision of the board it is possible to have 1xUART1 or 1xUART0 + 1xUART1. If having a board with 1xUART1 (board revision B, A13-OlinuXino-WIFI-DEV) the table with the signals can be found below: UART1 Pin # Signal Name Processor Pin # 1 3.3V - 2 SDC0_SCK 110 3 SDC0_DATA3 112 4 GND - Consider the above table when connecting the USB-SERIAL-CABLE-F according to the wire color code. If you have A13-OLinuXino with 1xUART0 and 1 xUART1 you may find the table with the signals below: UART0 Pin # Signal Name UART1 Processor Pin # Pin # Signal Name Processor Pin # 1 3.3V - 1 3.3V - 2 SDC0_SCK 110 2 UART1_TX 152 3 SDC0_DATA3 112 3 UART1_RX 151 4 GND - 4 GND - Consider the above table when connecting the USB-SERIAL-CABLE-F. Notice that UART0 data lines are multiplexed with the SD-CARD. Notice that UART1 data lines are multiplexed with the UART pins in the UEXT connector.

It is suggested to have an SD card with a proper Linux/Android image especially if you have ordered a version of the board without NAND memory. We have tested a number of microSD cards on the OLinuXino boards and all of them worked fine regardless manufacturer or capacity. However, keep in mind that some of the lower quality microSD cards might draw too much current from the slot which might cause power-state problems. If you suspect the microSD card is causing problems please try using another one of better quality for better results. microSD card connector Pin # Signal Name Processor Pin # 1 DAT2/RES 113 2 SDC0_DATA3 112 3 SDC0_CMD 111 4 VDD - 5 SDC0_SCK 110 6 VSS - 7 SDC0_DATA0 108 8 SDC0_DATA1 107 When removing the card, please make sure that you release it from the connector by pushing and NOT by pulling the card directly (this can damage both the connector and the microSD card).

If you feel insecure of your soldering/cutting technique it is better not to try to adjust the jumpers. The only really important jumper on the board is CE_NAND_E, which needs to be closed if you have board variant with NAND flash memory but you wish to boot OS from SD card. 6.8.1 CE_NAND_E When cut this board disconnects the NAND flash. Note that it is not a requirement to boot from the SD card since the processor has a routine of detecting such. The default position is closed. 6.8.2 3.3V_OPTION, 1.5V_E Both jumpers provide a test pad during production and debugging checking the supply voltages. It is not recommended to change their default positions. The default positions are closed. 6.8.3 5V_E The jumper provide a test pad during production and debugging checking the supply voltages. It is not recommended to change its default position. It is also useful if you remove the whole battery part of the board. The default position is open. 6.8.4 HOST_EN, 5V_E_WIFI, WIFI-3.3V/5V_USB These jumper provide options to setup the WIFI module to work on 3.3V, and/or the USB host to work on 3.3V. It is strongly not recommended to change the default positions, since then they will be directly powered from source which might cause faults of USB devices when disconnecting them from the hub. Default positions are: HOST_EN – open; 5V_E_WIFI – open; WIFI-3.3V/5V_USB in 5V_USB position.
