This is seen on ubuntu 20.04.1 aarch64 :

Probably harmless and easy to fix. Interestingly enough not seen on x86_64 - I assume it is because on x86_64, members of structures don't need to be aligned to 64-bit, so may be packed closer?

Hi, what is the procedure to compile and install those kernel modules for 64bit raspbian or ubuntu ?

HinTak commented 3 years ago

For current raspbian (they switched to v5.10 last week) you need this https://github.com/matrix-io/matrixio-kernel-modules/pull/53 - Afaik ubuntu focal is still at 5.4; likely ubuntu groovy is at 5.10.

When i try to follow procedure i receive following errors:

echo "deb https://apt.matrix.one/raspbian $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list deb https://apt.matrix.one/raspbian buster main

sudo apt-get update Get:8 https://apt.matrix.one/raspbian buster/main armhf Packages [4,422 B] Fetched 10.4 kB in 2s (4,672 B/s) Reading package lists... Done N: Skipping acquire of configured file 'main/binary-arm64/Packages' as repository 'https://apt.matrix.one/raspbian buster InRelease' doesn't support architecture 'arm64'

and i cannot install sudo apt install matrixio-creator-init

i have installed:

sudo apt-get -y install raspberrypi-kernel-headers raspberrypi-kernel git

correctly, but when i try to clone and make your #53 repo i get following error messages:

@floppy286 you likely need to do "git checkout -b v5.9 origin/v5.9" to switch to that branch, after cloning.

Thanks a lot! compilation passes smoothly but when I try to do sudo make install i get such warrning:

pi@raspberrypi:~/matrix/new/matrixio-kernel-modules/src` $ sudo make install

Skipping depmod. make[1]: Leaving directory '/usr/src/linux-headers-5.10.14-v8+' depmod -A cp matrixio.dtbo /boot/overlays

After performin last steps :

Add in /boot/config.txt

dtoverlay=matrixio

Finally, load the remaining required modules

sudo cp ~/matrixio-kernel-modules/misc/matrixio.conf /etc/modules-load.d/ sudo cp ~/matrixio-kernel-modules/misc/asound.conf /etc/ sudo reboot

i see added device in arecord and aplay but when i've try to do arecord i have the same efect as revievers in #53 - no sound is in fact recorded, no sound is played on matrixio mic

i have 5.10.14-v8 kernel

Thanks in advance
