    Thank you. I have given up on Libreelec on banana pro. However, I have quite some success with compiling mosterta's modifications for kernel and some other libraries to compile and run kodi for bananapro. See thread and my last post:

    hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy)


    Thank you majorkalina for your reply. As you know I did change the config to bananapi. The device boots fine, but does not play some of the video formats. How did your board work with kodi. Were you able to play mp4 and mpeg2 files? I appreciate any comments or suggestions.

    Thank you jernej.

    I am hoping that majorkalina does come to this thread and sees this request. I will really appreciate if can push the changes for BananaPi Pro.

    Very good news. I recompiled using bananpi config rather than banana_pro config. Now the system loads just fine on my banana pro. I played few videos from ripped dvds with vob format (I guess same as mpeg2). Some play just fine, while others have strange video. Like it repeats the pattern multiple times. Analog sound works.

    When I adjusted the player setting to disable HW acceleration, the same video with multiple parallel patterns, play fine, but cpu usage is close to 100%, so some skips every few minutes.

    Next I changed video from direct plane to EGL, and it becomes garbled.

    Does anyone have suggestions on what should I do next? At this point I am just about to call it quits, and wait for further development with A20 boards. On the other hand I am pleased to see a great progress so far. System is stable. Even if the video does not play properly or garbled, I can still get to reboot from power menu.

    Thanks jernej for all your help. Regards.

    That change is not needed anymore due to upgraded libdrm.

    As I actually don't own any A20 board and have no experiences with that SoC I can't really help you much more. Maybe majorkalina can push a changes needed for BananaPi Pro?

    Thank you jernej.

    I am hoping that majorkalina does come to this thread and sees this request. I will really appreciate if can push the changes for BananaPi Pro.

    majorkalina since you build image yourself, it will be quicker if you just change this line: ffmpeg-95.0002-add-common-v4l2-request-api-code.patch#l126 to +#include <drm/drm_fourcc.h>


    My source from git did not have this edit. So I also modified line 137 in the patch as shown above and rebuild the image. But still same error. The device boots but exits to command prompt which seems to have fully functional linux. But when I once again ran kodi from /usr/lib/kodi/kodi.bin, I got the same error: unable to create GUI. exiting.

    Looks like I am close to running kodi, I know majorkalina has run it on banana pro, so I should be. What am I doing wrong? First I cloned the main branch from your code and then checked out a20. Should I have used a specific version of the branch as outlined on Libreelec wiki? My steps were:

    1)git clone GitHub - jernejsk/ Just enough OS for KODI

    2) git checkout a20

    3) did the edit in uboot_helper as suggested

    4) PROJECT=Allwinner ARCH=arm DEVICE=A20 UBOOT_SYSTEM=bananapi_pro make image

    I know that there are issues with the video playing, but at least I should be able to get into the kodi interface. Looking forward to any help I can get. Regards.

    So I made some progress. With dtb file properly defined, the image boots, good. But it hangs after loading kodi. Here is a picture of my screen. What else do I need to do? By the way, I did not compile any addons? Should I? Thanks again for your help and any suggestions.

    Update: I tried to run kodi from the command line in /usr/lib/kodi binary kodi.bin and I get error: unable to create GUI. exiting.

    I forgot to mention, it has to end with .dtb, which is compiled version of .dts

    Thanks, I edited uboot_helper and changed line to dtb, as shown below.

    'bananapi_pro':{ 'dtb':'sun7i-a20-bananapro.dtb','config': ' Bananapro_defconfig' },

    It is compiling. Hope it works now. Thanks again. I will let you know how it goes. Regards.

    Thanks jernej. I am going to try building the image with your suggestion and come back here and report how it goes.

    I finished building the img file successfully, wrote it to microsd card and inserted in banana pro. Unfortunately, the system does not boot. It gets stuck on finding the dtb file. The dtb file, sun7i-a20-bananapro.dts, should be in LIBBREELEC partition where KERNEL is, but is not there. Here is ls -l command at sdcard LIBREELEC partition on sd card with image when punt back into my ubuntu system.

    [email protected]:/media/jhaveri/LIBREELEC$ ls -l

    total 104696

    drwxr-xr-x 2 jhaveri jhaveri 8192 Jul 4 21:19 extlinux

    -rw-r--r-- 1 jhaveri jhaveri 8372176 Jul 4 18:22 KERNEL

    drwxr-xr-x 2 jhaveri jhaveri 8192 Jul 4 20:15 'System Volume Information'

    and extlinux has extlinux.conf which is:

    [email protected]:/media/jhaveri/LIBREELEC$ cat extlinux/extlinux.conf



    FDT /sun7i-a20-bananapro.dts

    APPEND boot=UUID=xxxxx disk=UUID=xxxx quiet console=ttyS0,115200 console=tty1 (xxxx is really UUID)

    So at the same directory where KERNEL is, should have sun7i-a20-bananapro.dts, but is not there. Hence the system never boots.

    Thanks for any help. I know I am almost there.

    Fixed and rebased on latest master, which brings Kodi 18.3.

    Hi jernej: I am a noob and need some help building libreelec with kodi 18.3 for banana pro. I have so far used armbian with banan pro, but it will not compile kodi. I see in your post that I can build a libreelec image with kodi. I will really appreciate if you can send me some guide on how to do that for A20 board. I went to the main wiki, but it does not support A20, just A64, H3, and A6. I see you have a separate branch for A20 at GitHub - jernejsk/ Just enough OS for KODI , but I have no idea how to use compiling instruction from main wiki and build your image.

    What is equivalent command for bananapro device?

    PROJECT=Allwinner ARCH=arm DEVICE=H3 UBOOT_SYSTEM=bananapi_m2p make image

    I am planning to build this on a ubuntu virtual machine on Windows 10. Like I said earlier, I am noob, and need some more direction. Thank you in advance for your help.
