The DRAM settings are those from loboris. Identical with Xunlong's and linux-sunxi's. The adjusted ...

Can you confirm that this image behaves sane? Definitely has 4 CPUs reported

If it is ok, I will push changes to git.

I noticed that entire decoding/rendering loop is pretty single core. Without rendering optimizations, frames could still be skipped sometimes.

Seems to work (can not test it though since my USB peripherals aren't recognized).

All CPU cores up and one busy serving kswapd, temperature here (no heatsink): already 70°C. I thought about zsram but it seems more like a kernel bug to me so adding swap won't help: https://lkml.org/lkml/2013/3/17/50

Hi,

@Jernej
I have a problem with completing the kodi with your patches. The entire compilation looks fine but when linking kodi.bin pops up this error:

make [1]: Leaving directory `/ root / orangepi / Kodi / XBMC / lib / libdvd '
AR XBMC / cores / VideoPlayer / VideoPlayer.a
CPP XBMC / CompileInfo.o
AR XBMC / xbmc.a
LD kodi.bin
XBMC / cores / VideoPlayer / DVDCodecs / Video / Video.a (DVDVideoCodecSunxi.o): In function `CDVDVideoCodecSunxi :: GetPlayerPts () ':
/root/orangepi/kodi/xbmc/xbmc/cores/VideoPlayer/DVDCodecs/Video/DVDVideoCodecSunxi.cpp:444: undefined reference to `CDVDClock :: GetMasterClock ()

Do you know how to deal with it?

So I just want to chime in with my own experiences with the latest "sane" image you posted. Installation was smooth, setup worked great, did have to switch my keyboard and mouse to a different usb port since I'm using an Orange Pi PC. In terms of HDMI it was working fine, I threw a few things of my library at it and HW decoding was working as far as I can tell, didn't get a chance to throw a lot at it but will do later after work. Sound was also working through HDMI once I changed the output, it had defaulted to analog so I just had to select HDMI and I got sound. Temps seem reasonable as far as I can tell.
The only thing that I had issue with was MPEG2 decoding from my HDHomerunPrime which I assume was been done in SW vs HW. Not sure if that is something that can be fixed in the future or not, but so far great work.

I have updated the first post, also building OPI PC image now.

Yes. I missed this post.

I don't know how to change resolution to 1080p 60Hz.

I was able to change resolution to 1920x1080@60Hz by using this uEnv.txt:

bootargs=console=ttyS0,115200 quiet hdmi.audio=EDID:0 boot=/dev/mmcblk0p1 disk=/dev/mmcblk0p2 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 dmfc=3 consoleblank=0
uenvcmd=fatload mmc 0:1 0x42000000 kernel;bootm 0x42000000

Question: How do I enable/install PVR addons in this particular release ?
Or is it unavailable for this (unofficial) version of Openelec ?

you should be able to enable it in the settings under TV, it will then complain that you need an addon enabled.

Edit: System -> Settings -> TV -> General -> Enabled

Just did a pull request to jernejsk' repository to easily build images for different boards.

tried that, but it won't let me enable it...after the message/complaint it is still disabled.
Also there are no repositories that have PVR addons included, so maybe that is causing the issue... (see system > settings > Add-ons > All repositories)

If i edit uEnv.txt (in the same folder as KERNEL and SYSTEM) with the one you posted my screen remains black.
Is this the uEnv.txt to edit?
