SDK Configuration

Before compiling source code on the development machine for the target machine, the toolchain libraries for the target machine must be specified.

  1. Open a terminal window

  2. Navigate to the SDK directory. 

    developer@ldc:~$ cd /path/to/sdk/EMAC-OE-arm-linux-gnueabi-SDK_XX.YY/

  3. Run the script using the command shown below to produce a menu as shown in Figure 1. 

    developer@ldc:~$ ./setmachine.sh

    Figure 1. SDK Machine Selection Dialog


  4. Select the appropriate target machine type and press enter.
    The following should be displayed: 

INFO: Generating new default configuration file.
INFO: Using "./.emac_sdk.conf" as configuration file.
INFO: Using hardware configuration file:
      =>  EMHW_CONF = "/home/developer/EMAC-OE-arm-linux-gnueabi-SDK_4.0/.emac_hw.conf"

Setup complete!

Remote Upload Set-up

The global.properties file contains the fields necessary to contact and connect to the target board as well as the paths to the architecture specific libraries.

  1. Obtain the target machine's current IP address by issuing the following command from a shell on the target system: 

    root@emac-oe:~# /sbin/ifconfig eth0 | grep inet
    		For more information on how to connect to the remote system, see the initial connections section of the Getting Started Guide.

  2. Navigate to the projects directory within the SDK. 

    developer@ldc:~$ cd /path/to/sdk/EMAC-OE-arm-linux-gnueabi-SDK_XX.YY/projects

  3. Open the global.properties file with a text editor such as vi or gedit.
    The global.properties parameters are shown in Table 1 below.

    Configuration variable Description
    SDKBASE The base directory for the SDK.
    CC, CXX Exectuable binaries to use for compiling for the C and C++ compiler, respectively.
    LD_LIBRARY_PATH The path the linker should use to search for shared library files.
    CFLAGS The flags passed to the compiler to specify target processor architecture, debugging flags, etc.
    OFLAGS The flags passed to the compiler to specify optimization options to use.
    TARGET_IP The IP Address of the target machine (needed for uploading the compiled binary to the target machine).
    LOGIN The user name to use for logging into the target machine.
    PASSWORD The password to use for logging into the target machine.*
    WPUT The location of the wput command, along with options to pass to wput.
    Table 1. global.properties file contents


  4. Modify the TARGET_IP, LOGIN, and PASSWORD as necessary

  5. Save and close the file

The password is stored in plain text in this file. If development is taking place in a shared environment (such as a University lab) and secrecy of this password is required, simply ensure that only trusted users have read permission for this file. See Linux manual pages documentation for the chmod, chgrp, and chown commands. The user building the software will need read access to any file associated with the build.
