New reworked driver for Wolfson/Cirrus Logic audio card

So I'm confused.  I looked at your website RPi Linux driver for Wolfson / Cirrus Logic Audio Card   which said to use one of the precompiled kernals, I downloaded cirrus-linux-4.4.14.tgz, ran sudo tar zxf cirrus-linux-4.4.14.tgz -C / and got an error saying the file could not be opened.  The file was downloaded into "Downloads".  I tried it from Downloads, and got no errors.  I made the other reconfiguration changes you mentioned, and restarted, but Alsamixer doesn't recognize the Cirrus Card. 

1. Download https://github.com/HiassofT/rpi-linux

2. unpack

3. open terminal and cd into folder

4. enter next commands to configure kernel

    a) if you have RPi1:

          KERNEL=kernel

          make bcmrpi_defconfig

    b) if you have RPi2/3

          KERNEL=kernel7

          make bcm2709_defconfig

5. compile by entering commands:

make -j4 zImage modules dtbs

sudo make modules_install

sudo cp arch/arm/boot/dts/*.dtb /boot/

sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/

sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/

sudo scripts/mkknlimg arch/arm/boot/zImage /boot/$KERNEL.img

Note: On a Raspberry Pi 2/3, the -j4 flag splits the work between all four cores, speeding up compilation significantly. If you have 1 core do not input -j4. After commands make -j4 zImage modules dtbs it takes long time to compile.

6. Reboot.

7. Download https://www.element14.com/community/external-link.jspa?url=http%3A%2F%2Fwww.horus.com%2F%7Ehias%2Ftmp%2Fcirrus%2Fcirrus-…

8. Extract mixer scripts and from terminal:

./Reset_paths.sh -q

./Playback_to_Lineout.sh -q

./Record_from_DMIC.sh -q

In that case audio output from GREEN jack. Audio input from two microphones from card.

9. Disable RPi on-board audio device snd-bcm2835

disable it by removing (or commenting out) the dtparam=audio=on line from /boot/config.txt.

#dtparam=audio=on

10. Future updates without loss of sound:

sudo apt-mark hold raspberrypi-bootloader raspberrypi-kernel

11. And when you need update GPU firmare: sudo SKIP_KERNEL=1 rpi-update

12. Start Chromium with --no-sandbox option, like: chromium-browser --no-sandbox.

13. Set up PulseAudio to prevent difficult questions.

Hey,

thanks for the short set of commands but my rasp 3 fail at

make -j4 zImage modules dtbs

DTCO    arch/arm/boot/dts/overlays/midi-uart0.dtbo
arch/arm/boot/dts/overlays/midi-uart0-overlay.dts:4:39: fatal error: dt-bindings/clock/bcm2835.h: Datei oder Verzeichnis nicht gefunden
#include <dt-bindings/clock/bcm2835.h>

Have someone a hint?

Better don't use the ZIP download from github, this is known to cause problems. If you want to compile from source use git clone

git clone --depth 1 https://github.com/HiassofT/rpi-linux

Just tested this on RPi3 and "make bcm2709_defconfig", "make dtbs" worked fine.

so long,

Thanks for the fast reply.

Now it compile, but the Reboot fail. Is there a chance to find the Problem or I have to set OSMC new?

Edit:

So I try to install the driver several times with OSMC 12.2016 and cirrus driver 4.9.0 and 4.4.14.

Everytime the same. After a reboot OSMC surface can't start. Over SSH I have connection the Kernel is refresht to 4.9.0 and aplay -l say the driver is installed. I think the file system is corrupted because I can't do sudo apt-get update or install something after install cirrus driver. I found the system is in read only mode and boot is corrupted.

So I try:

fsck -y /boot

but no improvement. Have Some a Idea what I do wrong at installation?

I'm not familiar with OSMC but you could try looking in /var/log/syslog and/or the outputs of "dmesg", "journalctl -a" and "systemctl status" to get some more info what failed.

BTW: have you tried using a different SD card? If you see some filesystem corruption it could be caused by a defective card - this is happens quite often, unfortunately.

Thanks Hias for the commands to check.

- $ cat /var/log/syslog is empty

- $ dmesg is a to long for output but a Interessting Line is :

2.126616] VFS: Mounted root (ext4 filesystem) readonly on device 179:2.

and

2.920504] systemd[1]: Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory.

- $ systemctl status say: osmc    State: degraded ...

- $ journalctl -a say: no jounal files found

After that I found the command: $ systemctl list-units --failed

Output:

● systemd-hostnamed.service   loaded failed failed Hostname Service

● systemd-random-seed.service loaded failed failed Load/Save Random Seed

● systemd-update-utmp.service loaded failed failed Update UTMP about System Boot/Shutdown

Than I try to restart the Hostname with: $ sudo service systemd-hostnamed.service restart

Output:

Failed to restart systemd-hostnamed.service.service: Unit systemd-hostnamed.service.service failed to load: No such file or directory.

and the status of the service ( $ sudo systemctl status  systemd-hostnamed.service ) say the Problem which we isolate at start:

systemd-hostnamed.service - Hostname Service

   Loaded: loaded (/lib/systemd/system/systemd-hostnamed.service; static)

   Active: failed (Result: resources)

The Filesystem is read only mounted. So I try allready a second sd card but with the same result.

How can I prevent that the card mounted with read only?

I had a quick look at the OSMC sources and it looks like it uses a custom kernel build with an initramfs to setup stuff immediately after boot.

https://github.com/osmc/osmc/tree/master/package/kernel-osmc

So simply swapping out the kernel won't work, you'd have to build your own kernel with the same setup like OSMC needs (initramfs etc), eg by adapting the OSMC kernel build to use the sources from my github repo.

Thanks for look in.

How I have to do this. Must I bring the source code of osmc and yours together and compile it or can I Install osmc and modify yours with favorite osmc settings to recompile it. Sorry for the questions but rpi and kernel compilition is new for me.

Thanks for the support.

It depends. If the initrd is stored as a separate file and the kernel matches the configuration of OSMC's kernel it may be as simple as unpacking the initrd, replacing the kernel modules inside that with the updated ones from the precompiled kernel, repacking the initrd and copying it to /boot - similar to what I tested with volumio:

Re: Driver fixes and updates to kernel 3.18.16 and 4.0.5

If the initrd/initramfs is included in the kernel image or if OSMC needs some special kernel configs/patches it'll be a lot more complicated. Then you need to have a closer look at the OSMC build system, probably change a bunch of files/settings and recompile the kernel. If you never did this before this can be quite challenging and you'd better ask on the OSMC forums about the build system details.

Or you can just use LibreELEC instead of OSMC, my LibreELEC builds work out of the box with the cirrus card

Hey, thanks for the reply.

I have OpenElec already run without Problems but I want a little more functionality so I try OSMC. I think reconfigure the Kernel exceed my time quota at the moment. Thanks for the support.
