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 • 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 (optional) WIFI RTL8188CU 802.11n 150Mbit module on board • 1 USB OTG which can power the board • SD-card connector for booting the Linux image • (optional) 4GB NAND flash • VGA video output – 800 x 600 resolution • LCD signals available on connector so you still can use LCD if you diasble 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 addtional 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 • (Optional low cost 7" LCD with touchscreen) Page 5 of 37 OLIMEX© 2012 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 There are two major board variants. According to the names: A13-OLinuXino and A13-OLinuXinoMICRO. The base model has also 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 information on A13-OLinuXino-Micro will be added at a later time but so far the board is most likely to differ 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. 1.4 Organization Each section in this document covers a separate topic, organized as follow: – – Chapter 1 is an overview of the board usage and features Chapter 2 provides a guide for quickly setting up the board and software notes – – Chapter 3 contains the general board diagram and layout Chapter 4 describes the component that is the heart of the board: the A13 – Allwinner processor – – Chapter 5 is an explanation of the control circuitry associated with the microcontroller to reset.

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: - 6V to 16V, 6W required (6V @ 1A or 16V @ 0.4A) – for optimal power - LCD (preferably with touchscreen panel) display for the LCD_CON OR TV monitor with RGB port - A USB mouse – if you use touchscreen LCD you might skip the mouse 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 firmware update ot power A13-OLinuXino - 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 7 of 37 OLIMEX© 2012 A13-OLinuXino user's manual A 7'' LCD display with optional touch screen panel is available for purchase also: https://www.olimex.com/Products/OLinuXino/A13/A13-LCD7/ https://www.olimex.com/Products/OLinuXino/A13/A13-LCD7-TS/ Note that if you wish to use one of the LCD displays mentioned above you need to upload different Android image – configured for 480x800 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. 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. Page 8 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 2.4 Prebuilt software The A13-OLinuXino-WIFI board comes with Android 4.0 ready to use. The default settings of the software are followed. Note that the A13-OLinuXino (standard version without WIFI) lacks NAND memory and there isn't OS uploaded on the shipped boards (no Android). How we have installed the software? We have configured an Android image with settings suitable for A13-OLinuXino. Then using LiveSuit 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 9 of 37 OLIMEX© 2012 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 10 of 37 OLIMEX© 2012 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 (check the screenshot) Page 11 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 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 and finally we mount the NAND: mount -t vfat /dev/block/nanda /sdcard/nanda Page 12 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 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 800x600 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 2.7 Configuration of hardware in the Debian image 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 Page 13 of 37 OLIMEX© 2012 A13-OLinuXino user's manual CHAPTER 3: A13-OLINUXINO BOARD DESCRIPTION 3. Introduction to the chapter Here you get acquainted with the main parts of the board. Note the names used on the board might differ from the names used below to describe them. For the actual names check the A13-OLinuXino board itself. 3.1 Layout (top view) The picture above shows the initial revision of A13-OLinuXino. Note that the version of the board pictured does not have additional NAND memory nor WIFI module. Page 14 of 37 OLIMEX© 2012 A13-OLinuXino user's manual CHAPTER 4: THE ALLWINNER A13 MICROCONTROLLER 4. Introduction to the chapter In this chapter is located the information about the heart of OLinuXino – its microcontroller. The information is a modified version of the datasheet provided by its manufacturers. 4.1 The microcontroller CPU/GPU ARM Cortex-A8 Core 32KB D-Cache/ 32KB I-Cache 256KB L2 Cache Mali-400 3-D Engine VPU HD Video Decoding 1920*1080@30fps Support H.264, H.263, VC1, Mpeg1/2/4 Divx 3/4/5/6, Xvid, VP6/8, AVS etc HD Video Encoding Support encoding in H.264 format Up to 1920*1080 at 30fps DPU LCD Interfaces: CPU, RGB Memory DDR2/DDR3: Up to 533MHz 16 bits Data Bus Memory capacity up to 512MB MLC/TLC/SLC/EF-NAND 2 flash chips, ECC 64-bit Support NAND of 5xnm, 4xnm, 3xnm, 2xnm Support NADN of Samsung, Toshiba, Hynix Peripherals USB2.0 OTG, USB2.0 HOST (OHCI/EHCI) Page 15 of 37 OLIMEX© 2012 A13-OLinuXino user's manual SD Card V.3.0, eMMC V.4.2 SPI, TWI and UART integrated Audio Codec CSI R-TP Controller 4-wire resistive TP interface 2 points and gesture detection Boot Devices NAND Flash SPI Nor Flash SD Card USB Powerful Acceleration Graphic (3D, Mali400 MP) VPU (1080P) APU E-Reader Ultra-low System Power Consumption 15~20% lower than competitors Smart Backlight: auto adjust backlight acc. to the image display Package eLQFP176 More information can be found on Allwinner's web site at the following web-address: http://www.allwinnertech.com/product/A13.html Page 16 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 4.2 Block diagram The block diagram is taken from Allwinner's datasheet. Page 17 of 37 OLIMEX© 2012 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 18 of 37 OLIMEX© 2012 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. Page 19 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 6.1.2 UART1 interface The UART interface might be used for COM communication. 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 having A13-OLinuXino with 1xUART0 and the table with the signals can be found 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. Page 20 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 6.2 SD/MMC slot The microSD card slot is a standard 8pin connector. The SD card can be used for booting the operating system for A13-OLinuXino. 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). Page 21 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 6.3 UEXT module A13-OLinuXino has an UEXT connector and can connect with Olimex's UEXT modules.

Page 26 of 37 OLIMEX© 2012 A13-OLinuXino user's manual 6.9 Battery connector When using the battery connector keep in mind that it is an energy solution that wouldn't be able to power the board and all the peripherals. The voltage of a 3.7V LIPO battery would be enough to power the processor and the memory but won't be enough to power external touchscreen LCD. Pin # Signal Name 1 VBAT 2 GND The pins are also print at the bottom of the board under the connector. 6.7 VGA video connector The female DB15 connector is used for video output on a monitor. At the moment the maximum achieved resolution is 800x600 due to limited maximum frequency and the lack of integrated video controller in the chip.

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. 6.9 Additional hardware components The components below are mounted on OLinuXino but are not discussed above.

Introduction to the chapter In this chapter are located the schematics describing logically and physically A13-OLinuXino. 7.1 Eagle schematic OLinuXino schematic is visible only for reference here. You can also find it on the OLinuXino's GitHub repository: https://github.com/OLIMEX/OLINUXINO. They are located in HARDWARE section. You are allowed to view and edit the schematics as long you keep them free and you mention the source address (e.g. www.olimex.com). The EAGLE schematic is situated on the next page for quicker reference. Note that A13-OLinuXino-WIFI has all the components shown in the schematics. The stripped down version (A13-OLinuXino, without the -WIFI part) lacks two components: the NAND memory and the embedded WIFI module RTL8188CU. To reduce this document's size only one of the schematics is listed.

Note that we are primarily a hardware company and our software support is limited. Please consider reading the paragraph below about the warranty of Olimex products. Warranty and returns: Our boards have lifetime warranty against manufacturing defects and components. During development work it is not unlikely that you can burn your programmer or development board. This is normal, we also do development work and we have damaged A LOT of programmers and boards during our daily job so we know how it works. If our board/programmer has worked fine then stopped, please check if you didn't apply over voltage by mistake, or shorted something in your target board where the programmer was connected etc. Sometimes boards might get damaged by ESD shock voltage or if you spill coffee on them during your work when they are powered. Please note that warrany do not cover problems caused by unproper use, shorts, over-voltages, ESD shock etc. If the board has warranty label it should be not broken. Broken labels void the warranty, same applies for boards modified by the customer, for instance soldering additional components or removing components - such boards will be not be a subject of our warranty. If you are positive that the problem is due to manufacturing defect or component you can return the board back to us for inspection. When we receive the board we will check and if the problem is caused due to our fault and we will repair/replace the faulty hardware free of charge, otherwise we can quote price of the repair. Note that all shippings back and forth have to be covered by the customer. Before you ship anything back you need to ask for RMA. When you ship back please attach to it your shipping address, phone, e-mail, RMA# and brief description of the problem. All boards should be sent back in antistatic package and well packed to prevent damages during the transport. Page 37 of 37
