I bet your EMMC hidden bootloader doesn't match your image (I don't know how to better explain it). You need to do a eMMC bootloader recovery. Here a look here how to do it: en:emmc_recovery_xu3 [ODROID Wiki]

p.s.: I'm still desparate for news about a forced resolution

That is exactly what I tried. But the resolution is still 1080p:

Code

kodi:~ # grep 1280x720 /flash/boot.ini
#   setenv video_output "video=HDMI-A-1:1280x720@60"   :  720p (Use connected display's EDID)
#   setenv video_output "drm_kms_helper.edid_firmware=edid/1280x720.bin"  :  720p (Use system EDID)
#setenv video_output "video=HDMI-A-1:1280x720@60"
setenv video_output "drm_kms_helper.edid_firmware=edid/1280x720.bin"
kodi:~ # xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096
HDMI-1 connected primary (normal left inverted right x axis y axis)
   1920x1080i    60.00 +  50.00
   1920x1080     50.00    60.00    24.00
   1280x720      50.00    60.00
   1440x576i     50.00
   1440x480i     59.94
   720x576       50.00
   720x480       59.94
   640x480       60.00

Display More

The device is not directly connected to a TV, but to a Denon AVR. There it is on HDMI Input 1. So this should be correct?

Code

# cat /storage/.config/cec-hdmi-port.conf
CEC_HDMI_PORT=1

With Kodi CEC settings you mean "System Settings -> Input -> Peripherals -> CEC Adapter -> Physical address (overrules HDMI Port)"? Regardless of what I configure there, after a reboot it is set to 0 again...

Thanks for your help!

Hi,

first I wanny say thank to you fraggle for doing such a good job.

I am trying out your image on my Odroid U3. And have several issues:

1. resolution:

kodi boots up with 1920x1080p and I am not able to change it via the menu. (Menu options disabled). The native resolution of my Beamer is 720p but the odroid is connected via a Denon AVR 1912.

I tried several options in boot.ini to change to resolution to 720p but without success. I could change to resolution when kodi was running via ssh and xrandr-Command. There was still a picture after that but the GUI was somewhat broken and didn't resize properly.

Does anyone know of a way to force a resolution? Maybe xrandr-command at startup? Or what exactly to put into boot.ini?

I was unable to configure the Denon AVR to demand input at 720p. There are no HDMI options like this at all :-(.

2. CEC

I hoped that it would be possible to control kodi with my Denon AVR Remote. But nothing has worked so far. I was playing around with the cec-client command on the SSH shell to see if I get an error message, but it say that there is no link. I edited the hdmi_cec_config-File and tried to set sensible settings in the CEC plugin but I don't know exactly what I am doing...

Can someone recommend a CEC tutorial to get me started?

There are a few minor things (screen flicker in menu animations, spotify addon, standby activation), but those are the two main problems that keep me from throwing out my old satellite receiver.

Thanks a lot again and have some nice holidays..
