I'm not too familiar with that topic, you are probably better off asking this in the "General" thread of the XU3/XU4 forum, since this is not related to any OS or image you're using.

I've used tvheadend as well on the XU4 already whith both backend and client runinng on the same device. The results vary a lot from what i've seen. Some shows never had any issues, other had quite a few deinterlacing issues. Sadly i'm not too familiar with the decoder used for the XU3/XU4 to tell if that's normal or not.
You may want to try switching screen resolution to 1080i and see if that changes anything, but I'm not sure about this.
As I said, it's not my field of experience

Ok thanks for you explanation i will try first with tvheadend server and client both en switch my screen resolution to 1080i.

Then maybe start a new thread genaral XU3/XU4.

CEC is working fine too only thing i had to do was change the physical adress to 0x4000 and now it's working great.

Just finished installing tvheadend server, oscam and sundtek driver will try this out tonight.

Thanks for this great image!

Cheers!

i have done some serious dist-upgrade (to debian sid) and xserver does not start anymore.
i have an error msg

Code: Select all

 (EE) module ABI major version (19) doesn't match the server's version (19)

i assume it is the xf86-video-armsoc package, for which i should have a newer version - but i cannot find one.
what is to be done? (at the moment i am back on my previous jessie + version = it is more that i would like to understand how the process of updating/upgrading works here.

thank you!

meveric · Unread post by **meveric** » Mon Nov 30, 2015 11:36 pm

xf86-video-armsoc needs to match the XOrg Server version. If you upgrade XOrg Server you need to upgrade xf86-video-armsoc as well.
xf86-video-armsoc is NOT part of the Debian standard repository but needs to be compiled manually. I did this for Debian Wheezy and Jessie, that's why it's part of my repository and can be installed for ODROIDs.
But I don't have packages for sid (obviously since sid is changing constantly that's not possible) you need to download and compile xf86-video-armsoc manually if you want to update XOrg server.
Still I would advice AGAINST doing that. Debian Sid is very unstable and changes quite often, which means you would have to compile it over and over again.

Hi, a lot of work, nicely done and a major benefit to the community.

I may move my project to the XU4 from the C1+ and your OS sounds perfect for the job as it has the stability of Debian and a recent Chromium browser.

Your effort to compile Chromium for this OS is acknowledged, not easy, thanks.

Two questions:

Does Chromium support hardware acceleration?
Can I tx/rx with CEC device, either via cec-client or direct tx of raw cec commands (preferred)?

As peba said, HW acceleration for Chromium is working fine, you might have to start it with --use-gl=egl though.

CEC should be able to do the same as on the official ODROID image.
I know it's working fine in Kodi, and cec-client as well. Sadly I'm not too familiar with CEC so I can't answer specific questions to it

You actually were misled, chromium packages uploaded on his repo are just the same binaries provided on Ubuntu 14.04 LTS launchpad.

He's using different names "chromium-browser-odroid" so that it doesn't conflict with the chromium packages given by Debian Jessie provided on their official branch which seem to be outdated at the moment, unfortunately.

So, that's why we should use the ones available for ubuntu armhf branches, Debian team has not built up-to-date chromium-browser packages on their Jessie branch yet which is really sad, if they build them we will have much better compatible and optimized web browser.

Please stop telling lies, if you don't know what you're talking about.
These are NOT the same binaries as Ubuntu 14.04 LTS. It's the same SOURCES as Ubuntu 14.04 that's why it still shares the package names from Ubuntu 14.04 , but these packages are completely recompiled ON Debian Jessie, FOR Debian Jessie.

Hi @meveric

Thanks for verifying that HW acceleration works so let me clarify my cec question.

I have tried, as have others, to obtain C1+ support for either cec-client or /dev/cec for direct tx/rx but we have all failed to motivate it to happen.

Therefore, I need to move my project to another device and the UX4 seems ideal but having not used it I have not personally confirmed that cec-client works as it requires an active cec serial port for it's connection. This is not available on the C1+ and it seems that side is not interested in enabling this feature even though most of the work is done in the HK drivers I understand.

I can use cec-client but prefer to have the ability of direct tx/rx to the cec driver.

Either approach works for me, so do I understand correctly that cec-client is working in your image even if there is no direct tx/rx available to an application?

....................................... personal observational comments...................................................................

Many thanks for your efforts. I agree with your comments that many if not most of the HK product users come from Windows backgrounds or lesser linux experience than you and other OS developers on the board. If true, and I am one of them, I can tell you personally that I very much appreciate and respect all these efforts and frankly could not consider HK products without them.

I also regret the friction between good people on the board who are trying to develop image support for HK devices. I get it but would prefer if it were possible for these good people to create two OS development teams one for C1+ and one for the UX family. There are some constructive elements surfaced from the friction but prefer teamwork. That said, I am in no way criticizing anyone. You all deserve the pride you have in your accomplishments and to assert your beliefs and experience.

That said, I am supportive of your preference for the UX4 from what I understand (mine is shipping this week) as the 1GB RAM of the C1+ is a limitation for some higher demand projects but then again it is a lower price point and really should be compared more to the Rpi and there it compares well I believe.

meveric · Unread post by **meveric** » Sun Dec 06, 2015 2:53 am

Well, as I said, I'm not familiar with the CEC protocol.
All I can say is, that I can control Kodi with my TV remote if I activate CEC in Kodi on the XU3/XU4.
I can also start cec-client manually connect to the CEC entry on my TV and can see the buttons I press on my remote in the cec-client output.
That's pretty much all I can tell about CEC support.

I know there's a bug in the entire CEC software on the Exynos devices.. If you open CEC it never closes. This can result in you being unable to close Kodi since it's waiting for CEC to close all connections (which never happens).
And the same goes for cec-client. If when you start it only by killing the process you can end it. You can not exit the cec-client "normal".

tp1360 · Unread post by **tp1360** » Sun Dec 06, 2015 6:35 am

Thanks, what you say is good news as if cec-client starts and is attached to the cec port all is well and given it is showing your RC actions it should be good to go.

I use cec-client to tx cec commands e.g. echo "standby 0" | cec-client -s.

The error I get on the C1+ is "unable to find serial port" so if you are not getting that when loading cec-client, it should be good.

I will play with it when I get it next week.

The issue is that Kodi uses libcec in a different manner than cec-client so Kodi can work and cec-client not work.

Thanks for the information.

you first have to "SELECT" what you want to install by pressing "space".
If you only press enter it's like pressing the OK button, but if you have nothing selected first (by pressing space) it has nothing to do

I have a question about your image,

How many and which non-Debian packages (i.e. from your personal repo) are strictly necessary to run a minimal installation (command line only)?

I know there is kernel + headers, but any others?

meveric · Unread post by **meveric** » Sun Dec 13, 2015 2:49 am

nothing besides the Kernel is needed.. headers is just for compiling modules and drivers.
And besides Kernel and Headers nothing is preinstalled on the image that's from my repository

Not quite sure what is causing this. It should be something about the Real Time Clock.
Maybe HardKernel knows more about what's causing this.
Edit:
Seems it can be surpressed within the Kernel. I might create a new Kernel with the patch for that

You're using console only right?
Try the following:

Code: Select all

setterm -blank 0 >/dev/tty1 </dev/tty1
setterm -powersave off >/dev/tty1 </dev/tty1

If you're using a desktop environment you can set up the sleeping time of the monitor in the settings of your desktop environment.

It's not about manually editing config files.

That's somewhat odd. And rarely happens. When you unplugged and replugged the power plug, did it do anything at all?

Sch4f wrote:- how can i speak to the Xu4 Cloudshell TFT; its reacting while booting up, but it seems not have the right resolution

The TFT of the Cloudshell only has a resolution of 320x240 you can barely see anything with that

Normally it should be enough to follow this guide http://odroid.com/dokuwiki/doku.php?id= ... lcd_config to get the TFT to work on the CloudShell.
If you're using a graphical interface you might have to consider using a fitting XOrg configuration http://odroid.com/dokuwiki/doku.php?id= ... l_lcd_xorg

Sch4f wrote:how do it show me my system Stats.. ?

thx

On console you can run certain programs and output them on the TFT of the Cloudshell for exmple like this:

Code: Select all

setsid sh -c 'exec htop <> /dev/tty1 >&0 2>&1'

this will output htop on the TFT of the cloudshell.

You might want to take a look into @Fourdee's very goot DietPi image http://forum.odroid.com/viewtopic.php?f=98&t=15700 which is based on this Debian Jessie image.
It seems he can display many statistics on the Cloudshell TFT which are very useful. He also has tons of useful servers and programs scripted for easy use which you can choose from.

2. Clarification: NASA usually has many openings, and only a few of them are hitting the same domain. OTOH, the ones that do may well require you to prove a bit more in advance than you might like.

Hmm, what I normally do is the following:
after the first boot you should do a full system upgrade, means

Code: Select all

apt-get update && apt-get upgrade && apt-get dist-upgrade && apt-get autoremove

after that you should be able to install a desktop like MATE without issues.

I'll try in a little while myself to check if there's any new update that causes issues.
The image wasn't changed in the meantime, so it could only be that Debian made some new packages that are causing issues now, but as I said, I'll check on it in a little while.

Sch4f wrote:@ the FAQ to let the xu4 run, there is written i have to update the kernel via odroid-utility... doesnt conflict that to the dist-upgrade ?

Yes, the odroid-utility is only for HardKernels images, and in fact ever since 15.04 image it's also no longer needed to update the Kernel.
Please don't use odroid-utility, it's probably harmful to this image.

If assambled correctly you should have the USB 2.0 port free on the outside of the cloudshell. Using a USB hub should be good enough to control Wifi Adapter and keyboard/mouse, or whatever.
Another reason why Wifi is not working is, cause the firmware required for it is not yet installed.
Was it working on the XU4 previously? (for example with another image?)

Fun thing is, I never had issues with keyboard and stuff.. And I'm actually using a very cheap no name wireless mouse/keyboard and it works out of the box.
I changed keyboard layout to German, and don't have any issues. In fact when I install a Desktop it's asking what keyboard i want to use, and I select german.. after it's done and I'm on the desktop everything is working fine with german keyboard layout..
So normally it's rather easy. Question is, why issn't it for you. Do you have another keyboard you could try?

Hmm, you're right. I never bothered checking permissions on /. Thanks for the info, I see that I fix this after the holidays

It is normal, It's checking if the build and source directories are still the same as of when the Kernel was build, which they are not so in order to not confuse other programs that might want to build modules for the Kernel it removes invalid links. Still since the Kernel-Headers are installed, you should find a build link in /lib/modules/3.10.92+/ that is pointing to the Kernel Headers.
If you remove the headers and install the Kernel again, the build link will also be removed.
So yes, that's normal behaviour.

That's cause this doesn't work on FAT partition. The process is trying to create a "hard link" and FAT partitions do not support hard links. Since the boot partition is a FAT partition (in order to be able to edit it under Windows and all other operating systems) this throws an error. But it's nothing serious, you can just ignore it

Yes I was following that thread.. Initially I thought I could have been some issues with the Kernel but several tries showed it has nothing to do with the Kernel, by now I think it's about the different crypt libraries in Ubuntu and other OS system. If you have time to do it, you should try upgrading your system to Ubuntu 16.04 and try the benchmark there as well.. I'd like to know how a recent Ubuntu reacts to it.
maybe you can exchange the crypt libraries as well and see the same results on Debian.. I was playing around with that a little.. but without results by now.

Thanks for the explanations. As you can you tell the performance concern suddenly got real.

I was trying to upgrade to 16.04 but it was going to take over a day on my spare card, and seeing as the kernel modules are now a bigger issue I cancelled it.

I worry that I could be forced to use 4.2 kernel to fix the issue(s), but using mainline kernels on Debian stable is always bound to cause problems eventually...

And packaging... does regular kernel deb packaging work out for odroids? As in "make deb-pkg"?

Hi, I have a question about the kernel. I can see that there are more recent kernels, for example 4.2, available from debian's repository, is it save/OK to use those? If so would a "apt-get install" suffice to upgrade the kernel or is there other things I need to do?

Thanks!

Sadly it does not. It need quite some alteration. I still use make-kpkg but it requires quite some extras to build working packages

I still build Kernels often to keep up with new development and changes. And have some patches of my own compared to HK Kernels.

No, they won't work. The Kernels for ODROIDs have special modification to get graphics drivers, HDMI, and other things to work. Upstream Kernel right now is not officially supported and options with them are limited.
Means.. You probably could boot the device, but will most likely have issues with it, especially if you want to do anything else as using it as a server (means no 3D support, No Kodi, etc.)

Thanks for clarifying. Can you share how you build the xf86-video-armsoc package? I am planning to do a dist-upgrade to testing.

meveric · Unread post by **meveric** » Sat Dec 26, 2015 1:12 am

I guess you can try:

Code: Select all

git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-armsoc 
cd xf86-video-armsoc
git reset --hard ddd97ea
./autogen.sh --prefix=/usr --with-drmmode=exynos
make
make install
