Hi RagnerBG,
based on the howto from http://forum.kodi.tv/showthread.php?tid=254202 I start to compile mostertas Kernel. But, no luck - I cant compile the kernel because of some missing files in the GIT Repository (i reported it here http://forum.kodi.tv/showthread.php?tid=254202&pid=2257230#pid2257230) So far, i find out that the OpenPC TV Image is the best solution to run XBMC/Kodi on my Cubietruck (i have HW Accleration and can run DVBPlugins). But the Linix distro from OpenPC TV ist not my favourite, i want to have Debian . So, my idea was to extract the uImage, script.bin and /lib/modules/ from OpenPC TV and put it into Igos Armbian Image. This works so far: Debian is booting with the Kernel from OpenPC TV. In my opinion the Modul "sunxi_cedar_mod" should work, because it works on OpenPC TV, too . But i can't test the graphics on Armbian because i can't compile mostertas XBMC, too. I run into the exact same problems as yours an hang on this issue http://forum.kodi.tv/showthread.php?tid=254202&pid=2247864#pid2247864
I can't understand, why it is so difficult to run Kodi on Cubietruck. Unfortunately, I give up my hope and buy a FireTV Box.
