git clone git://github.com/OpenELEC/OpenELEC.tv.git
cd OpenELEC.tv
time PROJECT=RPi2 ARCH=arm make image
(get few cups of coffee…)

look under target/ there should be the image

if you want to rebuild kodi only
time PROJECT=RPi2 ARCH=arm make kodi

in my case I edit
vi build.OpenELEC-RPi2.arm-devel/kodi-14-b5dbdb5/xbmc/input/linux/LinuxInputDevices.cpp

added the home key for rii i7.

and here is the resulting patch

lircmap.xml in kodi / xmbc raspi2

I was missing the submenu button on my x10 rc for my raspi2 kodi setup. Following step where needed in order to set submenu button on the lower right button:

/storage/.kodi/userdata/Lircmap.xml
add:
<title>KEY_C</title>

.config/rc_keymaps/medion_x10
disable power button. useless currently for raspi, since it will turn on again. So I put mute there . And KEY_C for submenu.
# 0x02 KEY_POWER
0x02 KEY_MUTE
0x3a KEY_C

to read the table for lirc at startup
file .config/autostart.sh
#!/bin/bash
#/usr/bin/ir-keytable -c ; ir-keytable -w /storage/.config/rc_keymaps/medion_x10 ; ir-keytable -r
/usr/bin/ir-keytable -w /storage/.config/rc_keymaps/medion_x10

resize an raspi sd card image

losetup -f –show my.img
-> we have now mounted image as loop0

partprobe /dev/loop0
-> we have now the partitions which is required for gparted

gparted /dev/loop0
-> resize as usual now and apply

losetup -d /dev/loop0
-> loop not needed anymore

fdisk -l my.img
->
Platte my.img: 8068 MByte, 8068792320 Byte
255 Köpfe, 63 Sektoren/Spur, 980 Zylinder, zusammen 15759360 Sektoren
Einheiten = Sektoren von 1 × 512 = 512 Bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Festplattenidentifikation: 0x000981cb

Gerät boot. Anfang Ende Blöcke Id System
my.img1 8192 122879 57344 c W95 FAT32 (LBA)
my.img2 122880 15759359 7818240 83 Linux


so, end is at 15759359 (*512 bs)

so:
truncate –size=$[(15759359+1)*512] my.img

this should work now. if not, let me know.

new created SD card can resized then again with gparted.
