This repository is a fork of the KoboLabs e-reader that provides a build environment and a USB Host kernel for running XCSoar on a Kobo Mini.
This has only been tested on a Kobo Mini, but it will probably work on other new kobo devices
At present you can't boot your device between e-Reader and XCSoar without reflashing the kernel. This will be rectified with an 'auto-reflash' option in the boot sequence
Unfortunately the Kobo Kernel must be compiled with an older version of GCC (4.4) and XCSoar requires 4.6 or later. To resolve this you will need to build chains - one for the XCSoar packages and one for the kernel.

I used a new Ubuntu 12.04 Virtual Machine on my laptop

Install codesourcery GCC toolchain to /usr/arm-none-linux-gnueabi by untaring the downloaded archive into the /usr (ditching the arm2010-blah directory) directory
wget http://sources.buildroot.net/arm-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
bunzip2 arm-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
sudo tar -C /usr -xvf arm-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar --strip 1
- Changed the ownership of this directory to me (chown ...)
sudo chown ${USER}:${USER} /usr/arm-none-linux-gnueabi
- Install the uboot-mkimage tool
sudo apt-get install uboot-mkimage ncurses-dev
- clone repository if you already haven't
sudo apt-get install git git clone https://github.com/ifly7charlie/XCSoar-Kobo-Build.git
-
Change into the ./hw/imx507/linux-2.6.35.3-USBHOST directory
-
Run the make command
make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm clean uImage
- This will leave you a uImage file in arch/arm/boot/uImage
- To install to the boot SD card you have a few options
dd if=arch/arm/boot/uImage of=/dev/[your memory card] bs=512 seek=2048
or
copy to /mnt/onboard/.kobo/upgrade/uImage and touch /mnt/onboard/.kobo/KoboRoot.tgz then insert card and reboot kobo
or
copy to SD card (XCSoar installed), or normal Kobo plugged into laptop in .kobo/upgrade/uImage touch .kobo/KoboRoot.tgz then reboot kobo
note that the memory card is the WHOLE card, not a partition. So if your card is /dev/sdb use this not the root partition of /dev/sdb1. The kernel is installed outside of the filesystem at an absolute offset!
This is a two part process - one is seting up the build environment, which can be done using this git repository. The second is actually building XCSoar, which requires code from the XCSoar repository
-
Use a new VM - it makes the buildchain easier as you can't have the same compilers on both...
-
Get a version of the CodeSourcery ARM GNU toolchain which contains 4.6 or later (I built using 4.7)
-
Install it into the /usr/arm-none-linux-gnueabi directory (will have ./bin etc)
-
Change ownership so you don't need to compile as root (as above)
- Install g++ toolchain, this should go into /usr/arm-linux-gnueabihf directory
sudo apt-get install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf
- Change ownership so you don't need to compile as root (as above)
-
Change into the /packages directory
-
Run ../build/fetchxcsoarpackages.sh to download all the XCSoar specific packages
-
Install build tools that are needed
sudo apt-get install xsltproc imagemagick g++ librsvg2-bin libboost-dev These are all needed to run the build process, but don't need to be crosscompiled If your platform doesn't support pushd or popd then you should install them as well
-
change into build directory
-
edit buildsetup.sh to put the correct paths in!
-
run buildsetup.sh, which will configure this and start a build.
-
to restart you can just run the last commands from the buildsetup.sh script
-
Output for all the libraries will go into the /usr/arm-none-linux-gnueabi/[lib|include] directories
-
Clone the xcsoar repository somewhere
- Change into this directory and run make
make TARGET=KOBO KOBO=/usr/arm-none-linux-gnueabi
- Output will be in output/KOBO/bin
