It measures the width of a subbuffer. + * For datatype ISOC this may be for example 188 or 196 byte. + * \note This property is optional. If not set, the application will try to use default values. + * + * Copy the configuration to the target: \n + * Example: \n + * \code scp config.xml root@192.168.1.100:/root \endcode + * \note If you do not cross compile, you can skip the copy process. Otherwise you need to adapt the IP address according to your targets address. The folder is freely choosable, here: "/root". + * + * \subsection step5 Step 5: Setup INICs on all platforms + * \note InicExplorer V1 and Target Manager (InicExplorer V2) will run under Microsoft Windows operating systems only. + * + * The latest version of InicExplorer V1 can be downloaded from this URL: \n + * http://www.k2l.de/products/analysis-and-verification-tools/inic-medialb-tools/inic-explorer/inic-explorer-downloads + * + * The Target Manager (InicExplorer V2) installer is included in this package in the sub-folder "Resources". + * + * - The configuration of OS81110 is done with the InicExplorer V1 tool. + * - The configuration of OS81118 is done with the Target Manager (InicExplorer V2) tool. + * + * \note <b>Important hint:</b> The <b>MOST group address</b> set in the ConfigString is interpreted as DeviceType! \n + * This means certain types of devices share the same group address. \n + * Here some examples, configured by the config.xml shipped along with this package: \n + * - 784 (0x310): Server with OS81118 + * - 810 (0x320): Seat with OS81110 + * - 816 (0x330): Seat with OS81118 + * - 832 (0x340): Tuner with OS81110 + * + * Also there are example configuration files, for the Target Manager (InicExplorer V2) (FileEnding.jscs). \n + * \n + * Currently the VoD server application expects the OS8118 USB endpoints to be configured as following: \n + * Receive endpoints: + * - EP-81 = RX CONTROL + * - EP-82 = RX ASYNC + * - EP-83 = RX + * - EP-84 = RX + * - EP-85 = RX + * - EP-86 = RX + * - EP-87 = RX + * + * Transmit endpoints: + * - EP-08 = TX CONTROL + * - EP-09 = TX ASYNC + * - EP-0A = TX + * - EP-0B = TX + * - EP-0C = TX + * - EP-0D = TX + * - EP-0E = TX + * - EP-0F = TX + * + * For the OS81118 INICs attached to the server device do following steps: + * - Attach InicExplorer hardware to UART and connect it to the INIC connector. + * - Open Target Manager (InicExplorer V2) + * - Press the "Detect"-button. (If not found, try different COM instance) + * - Flash INIC firmware, provided by this package, by pressing "Flash"-button. + * - Select "OS81118_Vx_x_x_x_PV.mchpkg" and press the "Open"-button. Replace the 'x' characters with you version. + * - Make sure that in the next window there is "configstring" and "firmware"-check-box is checked. Then press "Ok"-Button. + * - Flashing takes some minutes. + * - After successful flashing, press "Explore"-button. + * - Press "Ok"-Button in the upcoming Package Selector dialogue. + * - Press "Load"-Button in the Configuration String Editor Window. + * - Select "inic-config-ga310.jscs", and press "Open"-Button. + * - Verify the settings, if they match to your needs. + * - Press "Write"-Button to write the configuration into the INIC. + * + * \subsection step6 Step 6: Load Linux driver on target + * Login into your target. This step will be necessary both for server and clients. \n + * Switch to the directory, where you have copied all outputs of the previous steps. \n + * + * In order to load all drivers and set them up in one step.\n + * Enter: \n + * \code sudo ./loadDriver.sh &\endcode + * \note The trailing "&" will run the script as daemon. It will run in background and set the driver up, whenever a new INIC is detected. \n + * + * \note If the device does not appear in the /dev folder, check if the USB device was registered to the system by typing: \code lsusb \endcode + * + * In order to unload the driver and the background daemon.\n + * Enter: \n + * \code + * sudo killall loadDriver.sh + * sudo ./unloadDriver.sh + * \endcode + * + * + * \subsection step7 Step 7: Enable Ethernet communication on MOST + * + * The "loadDriver.sh" shell script, started in the previous script, already started the MOST Ethernet device.\n + * But in order to get a correct network setup, you have to assign unique IP-addresses to each of your target. + * + * Login to the client target device. \n + * Switch to the directory, where you have copied all outputs of the previous steps. \n + * \n + * Check if the meth0 device is created. \n + * Enter:\n + * \code ifconfig\endcode + * \n + * Display Output:\n + * \code + * meth0 Link encap:Ethernet HWaddr 02:00:00:00:00:01 + * inet addr:10.0.0.1 Mask:255.255.255.0 + * BROADCAST MULTICAST MTU:1500 Metric:1 + * RX packets:0 errors:0 dropped:0 overruns:0 frame:0 + * TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 + * collisions:0 txqueuelen:1000 + * RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) + * \endcode + * \n + * The IP address 10.0.0.1 is already set in the shell script mentioned above.\n + * \n + * Use your favorite text editor to edit "loadDriver.sh".: + * - Example: + * \code vi loadDriver.sh \endcode + * - Or: + * \code gedit loadDriver.sh \endcode + * + * Scroll down to the StartEthernetUsb function, you will find the ifconfig statement which sets the + * IP address to 10.0.0.1. \n + * + * You have to adapt the address in this way, so it is unique in the whole network.
