Port Runeaudio to Odroid C1 (Arm v7)

hondagx35

Hi Tinitus,

there is nothing special in your debug data.

There were some strange messages concerning the wifi connection but I do not understand them.

Do you rember them?

Please tell me more about your environment:
- OS ?
- browser ?
Give me as much as possible info, so i can help to find the problem.

Then you connect from a windows machine with the host name,
you have to use bonjour and the url is http://runeaudio.
From OSX / Linux / Android it is http://runeaudio.local.

Please try to use the ip address instead and report.

I know three people who have installed rune successfully on the C1 and it runs very smooth.
So i think the problem is with your hardware (power supply) or your network .

You can try to disable ipv6 on your device by editing /boot/boot.ini
change this line:

setenv bootargs "console=ttyS0,115200n8 console=tty0 root=/dev/mmcblk0p1 rootwait rw no_console_suspend vdaccfg=0xa000 logo=osd1,loaded,0x7900000,720p,full dmfc=3 cvbsmode=576cvbs hdmimode=${m} m_bpp=${m_bpp} vout=${vout_mode} ${disableuhs} ${hdmi_hpd} ${hdmi_cec}"

setenv bootargs "console=ttyS0,115200n8 console=tty0 root=/dev/mmcblk0p1 rootwait rw no_console_suspend vdaccfg=0xa000 logo=osd1,loaded,0x7900000,720p,full dmfc=3 cvbsmode=576cvbs hdmimode=${m} m_bpp=${m_bpp} vout=${vout_mode} ${disableuhs} ${hdmi_hpd} ${hdmi_cec} ipv6.disable=1"

An other possible reason maybe power saving on your wifi stick.
You can try to disable it:

pacman -S iw
iw dev wlan0 set power_save off

If this helps it has to be made permanent, so it stays after a reboot.

nano /etc/udev/rules.d/70-wifi-powersave.rules

schould look like this:

ACTION=="add", SUBSYSTEM=="net", KERNEL=="wlan*", RUN+="/usr/bin/iw dev %k set power_save off"

Hi, tried to download the image, and when extract it with 7zip i get 0.img file,with winrar cannon extract it, so there is something with the image, can you give an alternative download link?
Thank a lot.
Got it, had to rename file.img.gz to file.img and wrote it to sd card and it booted

Tinitus

Hi Frank,

I thought it was strange that the device tried to load the driver for the wifi adapter twice. I tried your proposal to switch off the power save mode and that did not work. I then modified the boot.ini according to your proposal that did not help either. I then did exclude the ip addresses I use for static connections from the list of possible addresses awarded via dhcp this did not help either. But for the first time Runeaudio reconnected to the network, beforehand it only went and I was not able to reconnect once the connection was lost. I have both devices running now, one with Volumio and one with Runeaudio and I opened Mpod there is a page which shows you the signal strength of all devices running an mpd server with a wifi connection. Runeaudio was up for about 20 min. Volumio still has a connection half an hour later. I might have network problems (although neither my iphone nor my laptop running either W7 or Ubuntu 14.04 LTS ever get wifi drop outs) given the fact that although the device running Volumio is connected to the network it does not show up in the routers list of connected devices whereas the Runeaudio device shows up even if I am not able to connect to it. bonjour is installed under W7. May this be due to the fact that I set the static ip in Volumio by editing the file /etc/network/interfaces whereas I edited the static ip in Runeaudio through the WebUI? By the way I was not able to give it a secondary DNS address, is this absolutely necessary?

Best Regards

Hi Frank,

in Runeaudio the wlan configuration is in /etc/netctl

Description='wlan connection'
interface=wlan0
Connection=wireless
Security=wpa-configsection
Autowired=yes
ip=static
Address=('192.XXX.X.XXX/24')
Gateway='192.XXX.X.X'
DNS=('192.XXX.X.X')
WPAconfigSection=(
             'ssid="networkname"'
             'psk="XXXXXXXXXXX"'
             'key_mgnt=WPA-PSK'
             'proto=RSN'
             'group=CCMP'
             'pairwise=CCMP'
             'priority=3'

whereas in Volumio it is in the folder /etc/network file interfaces

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet static
          address 192.XXX.X.XXX
          netmask 255.255.255.0
          network 192.XXX.X.X
          broadcast 192.XXX.X.X
          gateway 192.XXX.X.X

wireless-power off
wpa-ssid networkname
wpa-psk XXXXXXXXXXX

auto eth0
iface eth0 inet dhcp

That looks less complicated to me. I know that the different methods to manage the network connection all link somehow into systemd, so I guess I cannot just uncomment the file in etc/netctl on the Runeaudio device and add a /etc/network folder with file interfaces and copy the file from Volumio. Would that work if I do:

# netctl reenable profile

I doubt it because first I do not know the profile name in Runeaudio and how should the OS know that what I wrote in the file interfaces concerns the wlan0 profile. Is there an easy way I could try the network settings of the Volumio installation in RuneAudio?

That the management of the wifi adapter is different in Volumio and RuneAudio is proven by the fact that the LED flashes if I run Volumio and glows steadily when I run RuneAudio (I swapped the two adapters between the two C1s and behaviour remains the same).

Hi Tinitus,

i tried a few other APs (NETGEAR, FRITZBOX) and now i'm able to reproduce your issues.
So please give me a few hours to fix the problems.

Sorry for the trouble you have with this new image.

Frank

Tinitus

Hi Frank,

no need to be sorry. Doing some testing is the only thing I am able to contribute to this project. I am using a speedport.

By the way I did not have any problems with the download or unzipping of the image file.

Best Regards

Hi Tinitus,

poking around i found an issue with the rtl8192 driver.
From your debug data i have seen that you use such a wifi dongle.

Please can you try this:

nano /etc/modprobe.d/rtl8192cu.conf

and add

blacklist rtl8192cu

and reboot

BTW: I found your posts on http://www.aktives-hoeren.de

Please report

Frank

Tinitus

Hi Frank,

do you mean this: (from ArchLinux Wiki about wireless Network configuration)

"Realtek

rtl8192cu

The driver is now in the kernel, but many users have reported being unable to make a connection although scanning for networks does work.

Package 8192cu-dkmsAUR in the AUR includes many patches, try this if it does not work fine with the driver in kernel. "

I thought I did not have Problems with that because I did not have Problems with my personal ArchLinux Trials. Would it be worthwhile tying a different dongle and do you know a type of dongle whch does not give Problems?

Tinitus

hondagx35

Hi Tinitus,

you only have to do what i have supposed in my last post.

It only takes you a few seconds.
Edit / generate that file and add:

blacklist rtl8192cu

to it.

The problem is, that both drivers (rtl8192.ko and 8192.ko) are installed, but the wrong
one is chosen by the kernel.

I thought I did not have Problems with that because I did not have Problems with my personal ArchLinux Trials.

Please try the above.
I made some test with an Edimax EW-7811Un and had the same issues.
After this modification all is fine and the blue light flickers as usual.

And here is my MD5 hash for 0.img
You are doing something wrong, there is no 0.img!
Use a program like 7-zip to unzip the downloaded image (RuneAudio_odroid-c1_0.3-dev_20150526_2GB.img.gz).
You should get a file named RuneAudio_odroid-c1_0.3-dev_20150526_2GB.img.
This file has to be flashed to the sd card.

Please read this.

Frank
I run with Win8.1 so look like my newest 7z still not possible to extract img correctly.

Hi Frank .

Could you be kind to add MD5 check for gz file and to post somewhere better bandwidth. I still can't get correct img file yet.

hondagx35

Hi thanhvo31,

Could you be kind to add MD5 check for gz file

md5 = 0226e7ac794f11f34f0b90429d4376d3

and to post somewhere better bandwidt

sorry not at the moment.

- download the file
- right click on that file in the explorer
- select unzip here
- use Win32DiskImager to burn it to sd

If you have no context menu for your 7-zip, then you have the wrong version.
Win 8.1 needs the 64-bit version.

Finally got image via my Nexus. My Win laptop look like can't handle gz properly.

Boot it smoothly, CD quality 44.1 kHz playback with ease. CPU usage 1%.

But problem arise with above 96 kHz file. 192 kHz too.

Please be reported Pi 2 handle those files well.

Finally got image via my Nexus.

Nice to hear.

But problem arise with above 96 kHz file. 192 kHz too.

Ülease give me more infos:
- DAC?
- where are the files stored (USB hdd, NAS)?

Hi Frank

DAC: HRT micro streamer and USB DAC of NAD D3020.(BOTH work well with Pi B, Pi 2.
File: store on MICRO SDCARD 64GB/ USB READER

The similar case was happened with Volumio for c1 too. A lot of pop and click.

Rgds.

Hi,

C1 arrived today, flashed the image and started testing

First, this is my debug info

Connected to my NAS and let the library do it's update in peace...

I did not manage to get the default HDMI audio out working.
Setting mpd to verbose logging shows: "All audio outputs are disabled" --> mpd would not start playing.
Did not spend much time on it really, HDMI audio was just for a quick test, not what I plan to use. Still, needs to be looked into for those who use an HDMI audio splitter.

Connected my USB XMOS 384K/32bit DAC, switched and all is OK, no clicks, no pops, no stutter, plays up to 352.8 kHz, 2822 kbps (stereo, dsd bit).
Have not yet noticed any difference with the X2 I just ported RuneAudio to, they're both a lot faster than a PI, the C1 is just a lot cheaper

What I did notice are the same network problems, configured a static IP but to no avail.
The UI does change eth0 in /etc/netctl to a static profile with the correct address, but obviously this eth0 profile does not get enabled.
DHCP is still being used. I will leave it that way for the time being.

There is also a problem somewhere with nmbd and smbd services, have not looked into it yet either, the X2 does not seem to have those issues.

Another thing I noticed when you reboot from the commandline:

PolicyKit daemon disconnected from the bus.
We are no longer a registered authentication agent.
g_dbus_connection_real_closed: Remote peer vanished with error: Underlying GIOStream returned 0 bytes on an async read (g-io-error-quark, 0). Exiting.

Broadcast message from root@runeaudio on pts/0 (Fri 2015-05-29 18:34:00 CEST):

The system is going down for reboot NOW!

@[deleted]: Did you by any chance install gstreamer0.10-good-plugins ? I remember this from the X2 port and then had similar problems, it installs polkit-0.112-2, which is not in the base ARCH Linux image for the C1. Are the gstreamer packages needed?

And to finish: thank you very much for all the work already done, will do more testing during the weekend.

Cheers - Gé

Sorry, forgot to mention that I also installed procinfo:

pacman -S procinfo-ng

And Spotify works like a charm

Hi Gé,

thank you very much for your report.

I did not manage to get the default HDMI audio out working.

Please update via git.
Then got to console and execute:

 php /srv/http/db/redis_acards_details

This adds "buffer_time 0" to mpd.conf and after reboot you should get HDMI audio.

What I did notice are the same network problems, configured a static IP but to no avail.

Should also be fixed after update.
netctl > 1.10 needs special settings in the profile settings ("ExcludeAuto=no")

it installs polkit-0.112-2, which is not in the base ARCH Linux image for the C1

For some reason (i didn't do that) there is pulseaudio installed on the system.
Please remove this:

pacman -R pulseaudio
 pacman -R  rtkit
pacman -R polkit

Frank

gkkpch

Aahh, that is were all the goodies are hidden

Wil have a look at and report back.

Hi Frank,

I'm getting this error

RuneUI updated successfully
error: Your local changes to the following files would be overwritten by merge:
app/libs/runeaudio.php
Please, commit your changes or stash them before you can merge.
Aborting
Updating a67e048..38c91fc

I presumed that is ok and corrected with

php /srv/http/db/redis_acards_details

Thanks for the polkit, rtkit and pulseaudio removal hints, X2 did not have pulseaudio.
I will retry with X2 and spotify later, though I doubt if anyone is going to be interested other than me
