1.) Don't have anything in dmesg. Maybe it happens because of CEC?

As you can see USB stick was mounted when I plug it in. Also shutdown works ok.

Also no problems here, everything's working fine on same build.
Perhaps some went wrong while installing, try redownloading and reflashing the image.

@franky384 I did run OpenElec from emmc and sdcard, no difference.

@vpeter I continued on 2)
Testet with MatrixTV v1.3 and connected to HDMI of my pc display

usb XBMC ssh time input lsusb
==========================
0 ok ok ok n/a yes*
1 ok ok ok 20** yes
1*** ok no no 20** n/a
2 ok ok ok 20** yes

* if no new usb device is connected otherwise no
** working for 20sec, ssh still possible
*** boot from SD (slower), will worsen the situation most of the time but not always

usb == external connected devices like keyboard, usb stick
XBMC == started after splash
ssh == ssh into MatrixTv
time == clock will be updated in XBMC HMI != 1. Jan 1970
input == usb-keyboard working with XBMC
lsusb == working

It look like after approx. 20 sec something bad is kicking in on my system, which than affects kernel input subsystem and maybe others too.

How did you run from sd card? I don't support that.

I'm sorry but I don't get what are you trying to say.

The u-boot installed by OpenElec release will check every sd/mmc from 0 to 2. If present it will load kernel, system and dtb from partition 1. The kernel will use the first available sd as mmcblk0. That means if you put an sd-card with OpenElec layout into MatrixTv it will boot from it! Which is good because MfgTool is PIA for me, I do not have Windows at home.

In prosa I meant, that OpenElec is very unstable for me. Some times it starts XBMC Ok sometime the screen is blank after boot. Sometime I am able to ssh into the box sometimes I am not able to start a ssh connection. One common observation is that an connected usb-keybord stops working after ~20 sec (I am permanently trigger the NUM Led by pressing the NUM Key) until then I can control XBMC with the keys. BTW XBMC uses one complete core (100%) on my MatrixTV.

Oh, I forgot on checking devices from 0-2

Anyway, I really don't know what causes your problems. Mine system is very cold in idle and on playback. Xbmc newer uses more than few 10 %. But maybe new releases will work for you too - it is still everything under construction.

Ok. I am building OpenElec right now.

What I did:
git clone https://github.com/OpenELEC/OpenELEC.tv.git
cd OpenELEC.tv
PROJECT=Cuboxi ARCH=arm make release

Do need more e.g Patches, config files to make it work?

This is not Cuboxi project! It's iMX6 which doesn't exist yet.

Yes, I am aware of that. That's why I ask for patches to share. BTW MatrixTV is also not an sabresd board .
First I will try to configure CEC out of the kernel. This one is a 100% blocker for me if the MatrixTv is connected to a TV. After that we will see.

If you really, really want to compile then in Cuboxi project options file add

Code: Select All Code

KERNEL_UBOOT_EXTRA_TARGET="$KERNEL_UBOOT_EXTRA_TARGET imx6q-sabresd.dtb"

to get dtb file. Everything else can be the same for now.

For CEC maybe you should tried different TV's.

And what do you mean with "MatrixTV is also not an sabresd board"?

And which image exactly did you use? Because I'm using the same kernel as Cuboxi where it works.
