Hi,

For some reason my chromebox lost its lan connection.
I already restarted everything and switched cables but no luck so far.
it is running openelec 5.0.2
I was wondering this is a known issue ?

I wanted to reinstall openelec to solve this problem but somehow i cannot get into the boot options either.
I need to hit esc at boot am i right ?
I have no idea what to do now, any help would be great!


Thanx

There is an option in OpenELEC to wait for network before starting Kodi. I had to set this for my network to work.

I recently switched my chromeboxes from dual-boot Ubuntu to standalone OpenELEC running OE 5.02. I am seeing the GPU hang problem on one of the boxes where the video freezes and the audio keeps playing. I've seen it happen twice now in the past 3 days. This is the same problem that I had in Ubuntu prior to upgrading the kernel. I thought this was fixed in OE. If not, is there a workaround outside of turning off hardware acceleration?

I had the same issue on two different chromeboxes; one setup as Standalone Ubuntu running Kodi, the other as a Dualboot with ChromeOS and Openelec.

On the Standalone, I updated the firmware then updated the kernel.

On the Dualboot, I updated the Firmware (from ChromeOS), and then updated Openelec to 5.0.x.

The issue hasn't reoccurred on either box since.

So, have you updated the firmware since 1/29/15? There was a VGA BIOS update which may be a contributing factor:

Per Matt's changelog in the first post of this thread.
2015-01-29 -- v3.10
------------------------------------------------------------------
- change lowest fan state from OFF to ULTRA LOW (~1900 rpm)
-- still inaudible, keeps system cooler overall, fixes Windows fan control issues (coreboot only)
- update VGA BIOS to latest Haswell/Broadwell version (1035); separate configs for ChromeBox/Book (coreboot and SeaBIOS)
- synchronized coreboot and SeaBIOS to latest upstream codebases
- minor script tweaks
---------------------------------

Regards,
Jake

I ran the install script last week, which upgraded the firmware in the standalone configuration (option 5). I'm sure this was after 1/29. Updating the kernel indeed fixes this for Ubuntu installs. I'm running OpenELEC, and that is not an option.

to quote fritsch, "logs or it didn't happen"

the VGA BIOS only affects video initialization when booting or coming out of suspend; anything related to video playback is driver/kernel related

the same fix in the updated mainline Linux kernel (3.18.4) was backported into OE 5.0.2, so that's not the issue.

If I have a second Chromebox (same model as the other) that I'm going to put a standalone openelec on, do I need to back up it's firmware or can I use the backed up firmware from the first one if need be?

[hdmkv]

This may be more an OpenELEC question, but let me ask to find out... I'm noticing when watching BD movie rips that when there are panning scenes, the movement isn't smooth. There's some judder. In Kodi, under Settings > Videos > Playback, I have "Adjust display refresh rate to match video" enabled, which I assume is correct.

I'd recommend backing up the 2nd box as well, since the firmware contains bits that are unique to that box (ethernet MAC address, serial number, etc). Plus, it's an 8MB file -- just throw it on dropbox etc for safe keeping.

assuming the source material is 23.976p and your TV accepts that as an input, then that's correct, and you shouldn't have any judder. Are you able to confirm the input refresh rate on the TV?

As I mentioned above and in the wiki, 3.18.4 is the min recommended since that's when the Intel GPU fix was merged in.

Which Kernel are you running?

Also, is there a viable way to do surround sound on the Chromebox?

[Matt Devo]

I'm running OE 5.0.2, which uses 3.17.7 I believe. Multichannel audio might require some configuration under Ubuntu, but that's not Chromebox specific; it works OOTB with OpenELEC

I just installed 3.19.

I guess I'm wondering how do you even hook up surround sound since there is only a 3.5mm jack and HDMI audio?

[Matt Devo]

You use HDMI, or a USB adapter like I do. The one I use is listed in the wiki

First of all, thanks for all the time you put in this, Matt! The whole process with your script went absolutely flawless!

I'm new to this, so sorry if there is an obvious way...
Is there an easy way to tinker around with fanspeed?
Can I somehow access the thermal.h file from coreboot and just manipulate it or would I have to clone your repository, do my changes, build and flash it?

[Matt Devo]

the OS can always override the firmware defaults, but if you want to change the latter, then yes you'd need to build your own. My repo contains all of the open source components of the firmware, but not the additional binary components needed - those would have to be extracted from your current firmware.

Thanks for your great work here. I'm using my two HP Chromeboxes together with openelec and they are working great
Except, that I would like to lower the fanspeed a lil.

Hopw would I do that in Openelec? Can you please help me out here?

Thanks again for your support
