Install on other OS (libreelec/kodi, volumio etc.)

[h4de5]

Hello,

I am wondering if it was possible to install and run the 4mic-array on any other OS than raspbian. I would like to install them on Kodi (https://github.com/LibreELEC/LibreELEC.tv) or Volumio (https://github.com/volumio). On both systems the install script fails:

$ ./install.sh
bash: 0: unknown operand

The current code has dropped older kernel (4.19) support, I think, and also too much bash-isms. Busybox's emulation of bash isn't up for it, I think. And I have never agreed with the whole check disk space and downgrade kernel thing , so you may have better luck with https://github.com/HinTak/seeed-voicecard . That said, it should be possible to rollback and get 4.19 support back again. (revert commits marked "v5.x" etc) . You probably want to follow some of the raspberrypi dev tips I wrote in the raspberrypi-dev repo. See https://hintak.github.io .

[HinTak]

I don't agree with the whole downgrade kernel thing which "Warning: /boot volume" is for.

[h4de5]

@HinTak thank you very much for the fast response and the idea.

I am trying to manually go through your install.sh script on libreelec.

• I copied the dtbo files and added the dtparam and dtoverlay strings to the config.txt
• dtparam and dtoverlay work - but they both don't show any loaded overlays after reboot.
• I left out anything related to kernel checks and apt-get (because apt-get wont work)
• I don't know what to do about the /etc/modules
• the commands i2cdetec and arecord are not available.

how far would I need to go back in the git history? I see the bigger changes are starting at around beginning of this year. and adding support for 4.18 at around march 2019. so somewhere in between?

[HinTak]

@h4de5 actually 5.4 support (for current raspbian /Ubuntu ) was only merged in summer 2020 (after many months of unhappiness of users being forced to stay in old OSes) - so you only need to roll back a few months. I'll make a v4.19 branch soon - just stay on that branch and you'd be fine, and I'd be interested to know what adjustments you need to make to make it work.

Your first 4 points aren't important, if you are happy with staying with one device and hardcoding that into your config.txt . A lot of the complexity is strictly speaking not necessary and only for dynamically detectino which respeaker it is and load the correct one. So that covers half of your 5th point too. To check that you have manually configure correctly you need to read your boot messages (dmesg).

It is a bit painful without arecord but maybe you have pyalsa (python binding of libalsa) or equivalent?

[HinTak]

The v4.19 branch on https://github.com/HinTak/seeed-voicecard is now synced to v5.5 with all the Ubuntu related stuff earlier this year, minus v4.19+ necessary code changes. So you should use that, and possibly let me know of any interesting distro-related modifications needed for you.

I don't work for Seeed Studio so maintaining two (current Ubuntu v5.4 and oldish Raspbian 4.19) and tracking a 3rd keeping x86_64 buildable on most current kernel (v5.9) is already beyond what I should... you are welcomed to click on the donate link at the bottom of https://hintak.github.io , if only to pay for a few SD cards to play with different OSes...

[h4de5]

wow. thanks a lot.
but I am not sure where to start from here. I switched to the new branch and run seeed-voicecard

thats the outcome.

I also found a way to install i2cdetect -y 1

there is no /boot/ folder - overlays are located in: /flash/overlays/
and /etc/ is readonly. asound.conf should go into /storage/.config/ (which I did)
i think asound.state should go to: /var/media/root/var/lib/alsa/asound.state (which I did)

still - alsoctl searches for the wrong path:

alsactl restore
alsactl: load_state:1683: Cannot open /var/lib/alsa/asound.state for reading: No such file or directory

I now also found a way to install alsamixer through Kodi's multimedia tools (not sure if this helps)

PS: I followed your advice about that buttons on your website - keep up the good work!

[HinTak]

@h4de5 that seems to have gone better than expected. So now we have a 3rd variants:

• raspbian Ubuntu kodi
  OVERLAYS /boot/overlays /boot/firmware/overlays /flash/overlays
  CONFIG /boot/config.txt /boot/firmware/usercfg.txt. ????

Possibly /flash/config.txt?

"bash: =~: unknown operand" is another busybox vs bash issue.

I think you need to have a look at /flash/config.txt. Adding a line
dtoverlay=seeed-4mic-voicecard to the config file manually is equivalent to all the i2cdetect and dtoverlay -d ..., so if you add that line you can drop most of
seeed-voicecard 's content. As I wrote earlier most of it is just trying to dynamically determine if you have 2-mics 4 mics or 6-mics.

[h4de5]

mmh. you are making me feel, like we could actually get this thing running..

I had put dtoverlay=seeed-4mic-voicecard.dtbo - which I fixed that now.

I also added this stuff (that I found on the internet, but actually have no idea about..)

dtparam=i2c1=on
dtparam=i2c_arm=on
dtoverlay=i2s-mmap
dtparam=audio=on

is any of this needed?

not sure about: usercfg.txt is there any way to test it without seeed-voicecard?

[HinTak]

I have downloaded the LibreELEC image and have a look. So I updated the v4.19 branch. The correct place is /flash/distroconfig.txt though /boot/config.txt includes the former and works too.

Since you seem to be able to run i2cdetect correctly, you don't need to worry about the dtparam stuff.

I think we need to see your dmesg output with the config.txt change and the card physically hooked up, that"s all. Curious libreELEC have aplay but no arecord! But you should be able to look at aplay -L and verify that the card is installed correctly, and use it to play some sound through the respeaker's phone output jack! (follow the instruction in the README).

[h4de5]

aplay -L:

null
    Discard all samples (playback) or generate zero samples (capture)

maybe a stupid question, but should there be any vital signs on the respeaker if its pluged in correctly? like would it light a led or something? I already changed the connector twice because I was not sure - but there is no led on at the moment.

[HinTak]

@h4de5 libreELEC has pacmd so you can use that to see if the recording part of the card is detected with pacmd list-sources . If that works, you might be able to use parecord instead of arecord to record off the 4-mics!

@h4de5 okay, your dmesg is half-way to correct - these two lines means your overlay is half-loaded:

[  791.433743] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/i2c@7e804000/status
[  791.544905] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/spi@7e204000/status

your question about LEDs: no, the leds are programable and you can play with them (I have a script which makes them do a spinning rainbow...), but they don't automatically light up.

@h4de5 since LibreELEC does not have dkms, we need to do things the old-fashioned way: if you do make, it should hopefully create a few "*.ko". make install should copy them to some place under /lib/modules/4.19.127 or /usr/lib/kernel-overlays/base/lib/modules/4.19.127 ?

The part of interesting dmesg on raspbian looks like this:

[    2.224602] snd_soc_seeed_voicecard: loading out-of-tree module taints kernel.

This is the 6-mics devices; I believe the 4-mics shows fewer ac10x lines, with a "codec count 1", and does not have the "input: seed-voicecard-headset" lines.

It appears that the libreELEC does not ship any dev tools, so unfortunately you may need to install "make", "gcc", "kernel-dev" and perhaps a few other dev-related packages before you can run "make" correctly to generate the "*.ko" files.

[HinTak]

@h4de5 I had a look at volumio - it turns out to be just old raspbian, so as far as I see it should just work, if you are careful about kernel header package installation.

[HinTak]

My notes -
https://github.com/HinTak/RaspberryPi-Dev/blob/master/LibreELEC-and-Volumio.md

It looks like Volumio is perhaps easier.

If your apt list -a raspberrypi-kernel on Volumio looks like this:

Listing... Done
raspberrypi-kernel/testing 1.20201022-1 armhf [upgradable from: 1.20200512-2]
raspberrypi-kernel/now 1.20200512-2 armhf [installed,upgradable to: 1.20201022-1]

You should be able to download the matching header,

http://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/raspberrypi-kernel-headers_1.20200512-2_armhf.deb

dpkg -i the downloaded file, then do apt-mark hold raspberrypi-kernel raspberrypi-kernel-headers and verify with apt-mark showholds that they are marked to stay not to auto-upgrade, and just follow ./install.sh as normal raspbian.

I'll put these in the Volumio section of the above doc.
