GPIO Joystick raspberrypi-kernel-headers

Hi all,

I am trying to install a driver called mkarcadejoystick, a retrosmc driver to use a Arcade Controller over GPIO. But two packages were missing: dkms, raspberrypi-kernel-headers.
I installed dkms, but i couldnt find the linux headers for 4.4.27-9 osmc, i tried the deb package ‘rbp2-headers-4.4.27-9-osmc’ and the linux-headers-4.4.27-v7+_4.4.27-v7±2_armhf.deb but it doesnt solved the issue.

Someone could plz help me?

Try the source package.
It’s best not to use DKMS though and more ideal to get modules upstream

Sam what do you mean, with “try the source package”, because i am trying to compile, and i cant find these kernel headers?
I tried everything, like installing a older version of osmc, but i couldn’t solve this issue.

I downloaded the kernel source and made a link

sudo ln -s /usr/src/rbp2-source-4.4.27-9-osmc /lib/modules/4.4.27-9-osmc/build

So now i think i got one more step forward:
Running the following command to install from deb package:

osmc@osmc:~$ sudo dpkg -i mk-arcade-joystick-rpi-0.1.4.deb
(Reading database … 79813 files and directories currently insta> lled.)

Any tips?
I i have to build the entire SO to have the correct /lib/module/‘uname -r’/build folder?

I (almost) solved this issue: (i can build now, but it doenst load )

install the kernel source:

sudo apt-get install rbp2-source-4.4.27-9-osmc

Link the src to the build folder

sudo ln -s /usr/src/rbp2-source-4.4.27-9-osmc /lib/modules/4.4.27-9-osmc/build

Go to the source folder and prepare for module build:

cd /usr/src/rbp2-source-4.4.27-9-osmc
sudo make modules_prepare

Download the deb package:

wget https://github.com/recalbox/mk_arcade_joystick_rpi/releases/download/v0.1.4/mk-arcade-joystick-rpi-0.1.4.deb

install package:

sudo dpkg -i mk-arcade-joystick-rpi-0.1.4.deb

But running:

sudo modprobe mk_arcade_joystick_rpi map=1,2
modprobe: ERROR: could not insert ‘mk_arcade_joystick_rpi’: Exec format error

someone could help me?

HI Sam, sorry but it doesn’t worked

I used the package source too:

git clone https://github.com/recalbox/mk_arcade_joystick_rpi.git
make -C /usr/src/rbp2-source-4.4.27-9-osmc M=~/mk_arcade_joystick_rpi/
sudo insmod /home/osmc/mk_arcade_joystick_rpi/mk_arcade_joystick_rpi.ko

Error:

insmod: ERROR: could not insert module
/home/osmc/mk_arcade_joystick_rpi/mk_arcade_joystick_rpi.ko: Invalid module format

I used the source package, do you mean i must use another kernel source?

Use uname and get headers for the currently running kernel

I am using the one downloaded from apt-get:

uname -a
Linux osmc 4.4.27-9-osmc #1 SMP PREEMPT Tue Mar 14 20:54:19 UTC 2017 armv7l GNU/Linux

I am using the following source:

sudo apt-get install rbp2-source-4.4.27-9-osmc

I am lost here.

make clean
make install
ensure in /lib/modules and try modprobe it.

I did it and wont worked,

sudo modprobe mk_arcade_joystick_rpi map=1
modprobe: ERROR: could not insert 'mk_arcade_joystick_rpi': Device or resource busy

To make sure that the kernel version is right:

sudo apt-get instal rbp2-image-4.4.27-9-osmc

l the module compiled using:

what i am doing wrong?

I don’t know what the cause of the error is. Address issues maybe?

I’d recommend contacting the author of the module about this. I am sure there are reasons the module is not found in the upstream Raspberry Pi kernel. Maybe it’s not ready or considered stable yet.

Sam

Thanks for your help Sam,

I am spending high amount of time to make this works, but i dont know how yet. I contacted the author already. I really want to use my home made arcade controller with rbp gpio’s.

Thanks for your time.

I understand.

If you are in contact with the module author, ask them what kernel version the driver worked on last, and on which devices they’ve tested with.

Sam

Sam, i have tested the other OS with a new kernel version: linux-headers-4.4.50 do you think that osmc could work with a new kernel version?

Yes – but we can only support the OSMC kernel officially.

We’ll release a 4.9 kernel soon, so you may have more luck then.

Good to hear.

I’ve found a workaround, using the RecalBoxOS together with OSMC, for this i am using this script (added a menu entry to enable this):

sudo su -c 'echo 8 > /sys/module/bcm2709/parameters/reboot_part'
sudo reboot

This way, i am using the full RecalBoxSO together with full OSMC, because the limitations of each distro does not affect the other distro. ( the game runs smother even with arcade controller / can watch videos )

Ps: The recalbox is installed in partition 8.
