Lately I have tested OpenElec for Raspberry PI and found out that it is very very fast, very very small and also it has some great addons(wifi, bluetooth and more).
Speed/size features on an 512MB RaspberryPI:
- a complete boot is less than 25 seconds
- cpu is around 30% load
- memory used is 32%
- total system size is less than 300MB
Edit. You can download my build from here(contains eGalax module and XBMC patches).
Username is root and password is openelec. The touch screen calibration file should be put in /storage/touchscreen_axes_calib.
Next, I will guide you through the instructions for building(cross compile) latest OpenElec for Raspberry PI with touch screen support.
For this tutorial let's assume that you have a Linux machine where you will work.
1. Get the latest OpenElec.
git clone git://github.com/OpenELEC/OpenELEC.tv.git
2. Add kernel touch screen module support.
Open the file OpenELEC.tv/projects/RPI/linux/linux.arm.conf and search for "CONFIG_INPUT_TOUCHSCREEN". Replace the whole text line with the following lines:
CONFIG_INPUT_TOUCHSCREEN=y
CONFIG_TOUCHSCREEN_USB_COMPOSITE=y
CONFIG_TOUCHSCREEN_USB_EGALAX=y
This step is not needed any more, because you can use the calibration addon to calibrate your screen.
Get the calibration addon from my Downloads folder and put it in /storage/.xbmc/addons/
5. Put XBMC 12.3 patch.
Get my latest patches from here and put them in the folder OpenELEC.tv/packages/mediacenter/xbmc/patches/
6. Build OpenElec.
Navigate to OpenElec folder and type:
PROJECT=RPi ARCH=arm make -j3
-j3 option is to use parallel build(if you have more than one cpu's set this number as nb_cpus+1). This option will speed up the build process.
The build process will take couple of hours, but you have to come back once(in the first 10 minutes) and press ENTER for the kernel touch screen modifications to be approved.
7. Install or Update your OpenElec card.
Go to OpenElec build instructions page for RPI and follow the "Install instructions" chapter.
Have fun!
