    ODROID-C1 are Ubuntu, Android, Fedora, ARCHLinux, Debian, and OpenELEC, with thousands of free open-source software packages available. The ODROID-C1 is an ARM device, which is the most wide- ly used architecture for mobile devices and embedded 32-bit comput- ing. The ARM processor’s small size, reduced complexity and low power consumption makes it very suitable for miniaturized devices such as wearables and embedded controllers.

    C1 also includes a 40-pin GPIO port, an external RTC battery connector, a USB-UART serial console port, an eMMC module connector, and a dedicated slot for a microSD card. For more details, refer to the ODROID-C1 introductory video at http:// youtu.be/DvJSCzIGr1E. ODROID C1 USER MANUAL...

  • Page 16: Heatsink

    Some owners prefer that the temperatures do not reach such high temperatures and install a heatsink, which is available from the Hardkernel store. Heat transfer from components to the surrounding air is related to the surface area available to transfer heat to the sur- rounding air.
  • Page 17 Chapter 1 to dissipate heat (approximately 1cm x 1cm). The heatsink is much larger and is therefore able to dissipate more heat into the surrounding air than the processor itself. Heatsink Installation Check that you have both parts of the heatsink. You should have a silver heatsink and a rectangular grey, gummy piece (the ther- mal pad).
  • Page 18 Chapter 1 Heatsink thermal pad applied Removing heatsink adhesive protection Heatsink applied to ODROID-C1 The heatsink’s purpose is to transfer heat from the processor and memory modules. Therefore it is normal for the heatsink to feel warm when the C1 is operating. A warm heatsink is actually a sign that the installation was done correctly and heat is being transferred from the modules to the heatsink.

    It is assumed that your unit has been through the initial setup procedure and is running the Ubuntu image from Hardkernel. • Open two terminal windows, where one window will be used to run the application used to test the processor.
  • Page 20 You may boot from either microSD card or eMMC module. Can I buy OS pre-loaded SD card or eMMC? Yes, they are available from Hardkernel as well as other distributors. Can I add extra RAM memory? No. The RAM is not removable or swappable.
  • Page 21 Use a 10/100/1000 LAN Ethernet connection, or purchase the WiFi module kit for a wireless connection. What display can I use? There is an HDMI Type-D output port on the ODROID-C1, and an HDMI Type-A on the C1+. Below is a list of resolutions that are cur- rently supported:...
  • Page 22 Is there an I2S port to connect a HiFi DAC? No, but an ODROID Hi-Fi Shield may be used with the ODROID-C1+. What is an eMMC module? The eMMC module is a NAND flash-based storage IC which is mount- ed on a custom PCB for easier upgrade/replacement, and is much fast- er than SD card.
  • Page 23 Chapter 1 Which power adapter should I use? The ODROID-C1 consumes less than 0.5A in most cases, but it can climb to 2A if many passive USB peripherals are attached directly to the main board. It is recommended to use the Hardkernel 5V/2A PSU or USB-to-DC Plug cable with a 5V/2A charger.

  • Page 24: Chapter 2 • Getting Started

    Getting Started iven the introduction to the C1 Single Board Computer (SBC) development board and the fact that you have all of the necessary peripherals, you must be excited to get started with your C1 now. To be able to use the com- puter on the Internet, we first need an idea of how the C1 will fit into a home computing network.

  • Page 25: Preparing The Work Area

    Chapter 2 Typical home computing network After preparing the boot media, it is theoretically possible to use a C1 in a network disconnected from the Internet. However, many use cases require an always-ON functioning secure connection to the Internet. In either case, it is presumed you have a fully functioning in- tranet (i.e., the internal network within the home).

  • Page 26: Flashing An Image

    If you refer to the annotated board image, you can see that the C1 supports two boot media types - microSD card or an eMMC mod- ule. They can be obtained from Hardkernel directly, either with Linux or Android, pre-installed. If you purchased one such device and if it has a factory-installed image, you can skip the flashing steps in this section and proceed to the next section.
  • Page 27 Chapter 2 Development boards such as the C1, by definition, will at some point either require an OS upgrade or a simple reflash to revert to a known good base state. The following section describes flashing the media. USB microSD card adapter No matter which boot media you select for your C1, you will need an additional device to perform the flashing process, which is called a USB SD card reader / writer.
  • Page 28 However, you can still use any brand or speed of memory card as storage. Sandisk Class 10 or UHS-1 cards are working well with ODROID-C1, and below is a list of the memory cards that have been tested: Fully compatible microSD cards •...

  • Page 29: Windows 7

    • PNY Turbo Performance Class 10 Class 2/4/6 microSD cards have not been tested with the ODROID-C1, therefore it is likely that the ODROID-C1 will not boot properly with them. We strongly recommend to use Class 10/UHS-I microSD cards, and a SanDisk microSD for fully compatibility.
  • Page 30 After the uncompress process, it will result in the image file that can be flashed. In this example, it will be ubuntu-14.04.1lts-lubun- tu-odroid-c1-20150204.img. Another essential utility is one that will be used to flash the un- compressed image file, such as the Win32DiskImager utility. Hard- kernel has an updated version of it that adds a useful step to the flash process, which clears the boot media prior to writing the image.
  • Page 31 Chapter 2 Uncompress the compressed image file using the 7-zip appli- cation, which generates the directory win32diskimager2-binary that includes the Win32DiskImager2.exe application. Move the entire di- rectory to C:\Program Files (x86): C:\Program Files (x86)\win32diskimager2-binary\ You will need to be logged in to Windows OS as an administrator to move this directory.

    Booting Up Ubuntu can be ordered as a pre-installation on the eMMC or mi- croSD card that comes with the ODROID-C1. Please refer to Chapter 2 for instructions on downloading and flashing Ubuntu onto your C1’s boot media. Once the C1 has been powered on, it will boot to a desk- top similar to the one shown in the following image.

    Chapter 3 Linux Basics Ubuntu and Debian, along with most Linux distributions, have a home folder structure where documents, files and media may be stored for each user of the system. For example, downloaded files from the Internet are automatically saved to the Downloads folder, and the other folders may be used to organize various public and private files such as pictures, video, and word processing documents.

    Chapter 3 which are video resolutions commonly supported on LCD TV’s and on many LCD computer monitors. 720p is sometimes referred to as HD, and 1080p as Full HD. The following comparison table lists the native display resolutions along with some sources that use these resolu- tions.

  • Page 43: Video Upconversion

    Chapter 3 For example, if you use a display that only supports native 720p, and you set your C1 to a 1080p screen resolution, it will probably work, but is not the ideal configuration. The mismatch in resolutions indi- cates that your display is automatically performing a downconversion of the incoming signal.

    Chapter 3 viewer, this results in a cleaner picture, and the overscan simply isn’t noticed. For a computer display however, this can be an issue. For this reason, computer LCD monitors usually do not provide overscan, and if they do have this feature, it is disabled by default. Disabling Monitor Overscan Prior to attempting to fix overscan using the methods detailed below, first verify that the monitor resolution setting and the C1 screen...

  • Page 45: Command Line Interface

    Chapter 3 On some monitor models, one of the HDMI inputs is intended to work with a PC and will disable overscan for that input (often HDMI 2). You can also look at the monitor’s HDMI connectors for a label such as PC Input, or read the monitor users manual to find the correct input to use if applicable.
