Preparation

  1. Make sure the following packages are installed:

    # apt-get install bison
    # apt-get install flex
    # apt-get install build-essential

  2. Install gcc-3.4:

    gcc 3.4 is required to compile gcc cross 2.95.3, however it's not supported by Debian officially any more, so we need to install it manually.
    First download the following packages:
    gcc-3.4-base_3.4.6-5_i386.deb from 
    http://packages.debian.org/en/etch/i386/gcc-3.4/download 
    cpp-3.4_3.4.6-5_i386.deb from 
    http://packages.debian.org/en/etch/i386/cpp-3.4/download
    gcc-3.4_3.4.6-5_i386.deb from 
    http://packages.debian.org/en/etch/i386/gcc-3.4-base/download 
    Then, install them according to the following sequence:
    # dpkg –i gcc-3.4-base_3.4.6-5_i386.deb 
    # dpkg –i cpp-3.4_3.4.6-5_i386.deb
    # dpkg–i gcc-3.4_3.4.6-5_i386.deb
    If installation is successful, "/usr/bin/gcc-3.4" will be created.

 Build Instructions

  1. Compile gcc-2.95.3:

    # export CC=gcc-3.4
    # export LD_LIBRARY_PATH=
    # cd /root/Desktop/2.95.3/crosstool-0.43
    # chmod +x *.sh
    # ./demo-arm.sh
    Upon success compilation, /root/Desktop/2.95.3/crosstool folder will be created.

  2. Compile gcc-3.4.1:

    Please logout and login again to resume the default environment. Then:
    # cd /root/Desktop/3.4.1/crosstool-0.43
    # chmod +x *.sh
    # ./demo-arm.sh
    Upon success compilation, /root/Desktop/3.4.1/crosstool folder will be created.

  3.  Compile gcc-4.0.3:

    # cd /root/Desktop/4.0.3/crosstool-0.43
    # chmod +x *.sh
    # ./demo-arm9tdmi.sh
    Upon success compilation, /root/Desktop/4.0.3/crosstool folder will be created.

  4. Compile eSlick firmware:

    # cd /root/Desktop/build
    # chmod +x *.sh
    # ./build.sh
    Upon success compilation, the following files will be created under /root/Desktop/build folder:
    u-boot.bin    The boot loader;
    uImage       The Linux kernel;
    rootfs.img     The root file system.

Installation

Please download command line updater from the following URL:
http://exchange.foxitsoftware.com/qwy/eslick-source/cmdline1130.tar.gz , and extract to the folder where those firmware files reside.
Instructions for updating eSlick firmware:

  1. Connect eSlick device to your Linux desktop using USB cable;
  2. Make sure eSlick device is in update mode. To enter this mode, press the "Reset" button using a pin thru the hole on the back of the device, then press Power and Menu key (the second top key in the four keys on left side) at the same time for a few seconds. The screen will show things like "Firmware Update";
  3. Use the following command line to update u-boot file:
    sudo ./cmdline -u u-boot.bin
  4. The device will display progress bar for "Receiving Data...", and then "Updating ...", and then "Receiving data..." again. Now the update is done, press "Reset".

You should repeat the above operations for kernel updating, but using the following command line:
sudo ./cmdline -k uImage
and then for file system:
sudo ./cmdline -r rootfs.img
