How to compile GPL packages and build the firmware.


Install a Linux distribution

  The whole building process have been tested on Fedora 8. The installation 
  instructions here is also for Fedora 8. Other Linux distributions should be 
  also fine but may need to some expertise to configure your working Linux 
  environment.


Prepare the development environment

  This section explains how to install the development software onto the host 
  Linux. This is a demonstration version of MontaVista Linux Pro v5.0.

  Go to the location where you will unpack the tar file.
  
    host $ cd /opt
  
  Unpack the tar file (as root) by using the following commands:
  
    host $ tar zxf mv_pro_5.0.tar.gz
    
  This creates the MontaVista directory structure under the 
  /opt/mv_pro_5.0/montavista/


  Install LZO -- a real-time data compression library (as root)

    host $ cd ~/
    host $ tar zxf lzo-2.03.tar.gz
    host $ cd lzo-2.03
    host $ ./configure
    host $ make
    host $ make install


Prepare the working environment

  Unpack the tar file by using the following commands:
  
    host $ cd ~/
    host $ mkdir gpl
    host $ cd gpl
    host $ tar zxf DVS-310-1_FW_v1.00_GPL.tar.gz


Setting Up the Build/Development Environment

  Use the following command to set up your development environment

    host $ cd ~/gpl/DVS-310-1
    host $ source setenv


Compile source code and build the target firmware

    host $ cd ~/gpl/DVS-310-1
    host $ make install

  The target firmware will be built at ~/gpl/DVS-310-1/firmware/update.bin
