My first goal is to figure out a way to easily upload files to the root file system. I'm not confident I could make a custom yaffs2 image that would actually work and I don't want to wear the Kobo prematurely by flashing it repeatedly with tests. Sadly, trying to stick scripts in mfg_test/mfg_test or vform/update_vform on the SD card isn't working. The only other idea I have is to figure out the USB protocol used when updating the firmware. Foxit had a command line tool for updating their eSlick's firmware in Linux here: http://www.foxitsoftware.com/ebook/gpl.html but, just my luck, all the links are dead and I can't find a mirror.
If I'm able to customize the Kobo a bit (changing the fonts or running 3rd party software) then I ultimately would like to get OpenInkpot running. |

GPL Compilation Instructions for eSlick Firmware update 2.0.1 Build 0205
Environment
Please install or use a clean Debian system, with Internet access.
You can install a latest version of Debian on a new machine or virtual machine from
http://cdimage.debian.org/debian-cd/...86-netinst.iso .
Please login as root since some operation requires root privilege.

Please put all these files onto desktop of root user (/root/Desktop) and unpack them directly under that folder.
Preparation
Note: You should have to login as a root user to do the following operations. If you're using the debian, Ubuntu or Fedora operating system, please enter the sudo or su command to convert your account to the root user. For other Linux systems, please convert to the administrator account first according to the corresponding system command and then do as follows:
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/i...c-3.4/download
cpp-3.4_3.4.6-5_i386.deb from
http://packages.debian.org/en/etch/i...p-3.4/download
gcc-3.4_3.4.6-5_i386.deb from
http://packages.debian.org/en/etch/i...-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/eb...ine1130.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
