Raspberry Pi Zero Support in 0.4

rlsten

I've successfully got Rune to work on a PiZero with a hubpiwi, which adds wireless and 3 standard USB ports. Many thanks to hpeter and Frank, and to rumina from the Head-Fi forum!

To get wifi going, I made a new profile in /etc/netctl with the same name as the SSID of my network, and then copied the settings of my profile from another installation of RuneAudio on a Pi3 to the new profile. I then entered the following command:

netctl-auto enable MYPROFILENAME

For some reason, hpeter's image was slightly larger than a Sandisk 8gb microSD card. I managed to load it on a 16gb card. I don't really know how to shrink a partition so any help on that using Windows or Rune itself would be appreciated, since I don't have an independent linux machine.

Also, I needed to install utilities to support exfat (necessary for large SD cards) and ntfs file systems. I installed the following:

for exfat

pacman -S exfat-utils

for ntfs

pacman -S ntfs-3g

I noticed that config.txt did not include the option to provide more power to USB. I added the following at the bottom:

max_usb_current=1

Has anyone tried Frank's suggested settings in config.txt for the Cpu:

arm_freq=1000
gpu_freq=300
core_freq=400
over_voltage=6
force_turbo=1

If so, do they work?

Hi Rod, you cud extend the microsd card as this instruction http://www.runeaudio.com/documentation/troubleshooting/extend-partition-sd/

Hi @[deleted] Yes wifi worked fine once I had the wifi configuration correct. The pHAT DAC from pimoroni.com also worked perfectly with Rune Audio. All I had to do was enable the device tree for HifiBerry.

Yes that ENC28J60 Ethernet card is what I used. They are available from a variety of manufacturers. Note that some of them have different pin numbering to others. You should not have to resort to using one of these. You should be able to get wifi working simply by setting up the configuration files correctly. However if you do have one handy it is a very easy way to get connectivity into a pi zero for fault finding.

dunghnguyen wroteWhat a pity as they don't ship Pi Zero to my country

Really? Who have you tried? Pimoroni.com say they ship world wide, and do not mention any restriction for Pi Zero on their website other than only one per customer.

dunghnguyen

Thanks for your confirmation and advice @[deleted]. I tried with Pimoroni but they don't ship to my country as well

PROBLEM SOLVED, FINALLY!!

I have attach USB -> Ethernet dongle to Zero and reboot Rpi. Then no network interfaces was on ifconfig. Pull out WiFi dongle, reboot, and there was ethernet with IP4 address! Put WiFi dongle back to USB hub, reboot and connect to Rune via web interface with Ethernet IP address. Switch to network and search for my SSID.Have found it, put wifi pass and press connect. There was green arrow that indicated that network is connected but there is no IP assigned for WLAN0. No problem, delete this network, create new and now connect to it with static IP configuration. Reboot, pull out Ethernet USB dongle but there is no connection

After a few try's I have found that TP Link TL-WN723N don't work with Rune ver.0.4 . Have put another WiFi dongle in USB hub and now I'm connected with my WiFi!
This (TL-WN723N) work with Rune 0.3, work with Open and LibreElec and with Raspbian. Why it don't work with ver 0.4? I think there is a problem with this Linux distro, because now I remember that I have try 0.4 version on my Raspi 2 and also WiFi dongle didn't work. It seems that it is working but no traffic goes through it.

Update:
I have put this in my config.txt:

max_usb_current=1
arm_freq=1000
gpu_freq=300
core_freq=400
over_voltage=6
force_turbo=1

and after reboot I have this line in debug:

 bcm2835-cpufreq: min=700000 max=1000000

So, I think Zero is now working on 1Ghz as is supposed to

But how can I setup my sound card? As I remember it was easy to do in Rpi2, only heve some line to uncomment and it was working. Can I jus t add line in Config.txt or it is done in some other configuration file? And is it a pin cofiguration on GPIO same as on Rpi2? Asking that because Zero have Raspi 1 CPU but GPIO like Raspi2

Hi flega,

Asking that because Zero have Raspi 1 CPU but GPIO like Raspi2

Modell A+, Modell B+, Pi 2 Model B and Raspberry Pi 3 Model B all have same GPIO pinout.

But how can I setup my sound card?

Which one? Hifiberry, IQAudio or something else?
Go to the settings page and enable I2S, that is all you have to do.
If it doesn't be there, we have to modify the platform ID.
Please post your debug data.

If you like

This one . I use to set it like hifiberry-dac and it work ok

It is there, I have set it like Hifiberry-dac, press apply, reboot, but there is none thing in MDP, only small grey square. i also try Hifiberry-dac+ but it is same in MPD Audio Output Interface as with Hifiberry.
When I add

dtparam=audio=on

to my config.txt and reboot, there is RaspberryPi Analog Out and RaspberryPi HDMI out in MPD Audio Output Interface.
Should I post debug?

hondagx35

Hi flega,

Should I post debug?

If it doesn't hurt, yes.
And also please post your config.txt.

I need the kernel version, to see if it uses device tree to configure drivers.
If so, please read this.

Frank

flega

Debug ist here

Config.txt is here

hondagx35

Hi flega,

- disable I2S on the settings page
- delete the file "/etc/modprobe.d/snd-soc-pcm512x.conf"
- add this

dtoverlay=hifiberry-dac

to your config.txt

BTW your debug data looks good beside this messages:

[   45.568491] cfg80211: Timeout while waiting for CRDA to reply, restoring regulatory settings
[   45.568520] cfg80211: Restoring regulatory settings
[   45.568596] cfg80211: Kicking the queue

Please try this:
- install crda

pacman -S crda

- select your country code in /etc/conf.d/wireless-regdom or choose 00 for world wide

Can't update crda, something is wrong with this package. I'll try this later, but most important is that I have working Zero with Rune on it playing. Thanks again to all!!

Hi all!

awesome work! After two days of trying to install arch, pimusicbox and so on I found this forum post!

It's working well and I shrinked the image for usage with SD Cards <8,5GB.
Does anybody know a good side for uploading a 1,7GB file?

No. The image provided was greater than 8GB with 6GB unused space. To flash it to a 4 or 8GB card I had to shrink the partitions and delete the unused space from the image.

@[deleted]: Hi Frank ! Finally I had the RPi0 now. I have no any issue at all to flash the image on a microSD card 16GB. I tried running that it played perfectly. No issue with LAN even the wifi dongle connection.

The issue I had now are:

- Playing WAV perfectly
- DSD / Hi-Res / Flac are very distorted via usb to external DAC

The bebug of my case is attached from here http://pastebin.com/g3qwyQbF
As well as the config.txt here http://pastebin.com/UGRsYcRX that I added to activate the HiFiBerry DAC that I am going to test the sound decoded via I2S very soon. For this, I will keep you posted for any further.

Thanks for your attention and any advice is highly appreciated.

I would to say my thanks to @[deleted] for his contribution.

Wifi worked perfectly for me but I wish to try to see any impact from any corner

so I tried with ENC28J60 as per your advice that it connected perfectly as well. I will use it in case making diy + a design case for RPi0. Thanks buddy !

I've just installed runeaudio on a Pi Zero using this thread. Very happy - I spent rather too long trying to get Volumino to work - and this was comparitively simple - at least the OS is standard underneath, and vi hasn't been removed

I used the image uploaded here by hpeter.

Here is the link to the image file which is zipped using gzip:

http://www.mediafire.com/download/kzy8txlqadxly48/20160618_runeaudio_raspberry1_raspberryZero.img.gz

The SHA256 hash of the file is: d303bbb82f8171d7e529ace2bd05dff390fdd4c9726f808c2e2e4a43079447f2
http://www.mediafire.com/download/c846hxue9sfwr3c/20160618_runeaudio_raspberry1_raspberryZero.img.gz.sha256

As others have said it's actually too big for an 8Gb card. Took a while to work out how to shrink it - I used dd on OSX

dd bs=512 count=3481600 if=20160618_runeaudio_raspberry1_raspberryZero.img of=mynewrune.img

I've also added the extra config.txt items to speed up the zero to 1Ghz, and max usb current:

max_usb_current=1
arm_freq=1000
gpu_freq=300
core_freq=400
over_voltage=6
force_turbo=1

First boot I used a screen and keyboard so I could configure my wireless connection correctly.

I then configured my IQaudio PiDACzero

It all appears to work, except airplay. I can see runeaudio in my airplay menus on phone/ipad, but I get no audio from the speaker. I can play a radio stream, and music from an OSX share.

Debug info here http://pastebin.com/tamv4WKA

Other things:
Should I try and update this with a nightly build? Don't want to break it all now it's working, but when I login I get

RuneOs: 0.3-beta (build 20141029)
RuneUI: 1.3
Hw-env: RaspberryPi

I have the CRDA error (what is it??)
trying

pacman -S crda

give file retrieval errors - see http://pastebin.com/vhHmFPYW
