Player 2 controller not working

mitu

Ok, so it seems that the GPIO based joystick is recognized by Emulationstation, but not by RetroArch (where only the PS3 clone gamepad works). Probably this will be listed in the log output (/dev/shm/runcommand.log) of RetroArch.

An update couldn't have erased any file in /etc/modprobe.d/, those are not part of any upgraded package. It's also normal that there is no mk_arcade_joystick package, since the module is compiled from source (it's an optional package in the drivers section of the RetroPie-Setup), but it should be registered with dkms. Being registered with dkms would re-compile the package on kernel updates, but not configure/re-configure it.

I think your course of action involves creating a .conf file for the module and checking if the module is correctly loaded, then checking if the /dev/input/js[0,1] input device is created. After any modifications, you should check the RetroArch log file I mentioned in my previous post and see if the gamepad is detected.

EDIT: looking back over your posts, you mentioned something about a 'C program' to map the cabinet gamepad. I think that program is Adafruit's retrogame. This is why you have a 'retrogame' as an input device, which emulates a keyboard and not a proper gamepad (buttons + joystick). I think that the setup you have doesn't use the mk_arcade_joystick module at all (hence the empty configuration file). RetroArch doesn't see a gamepad, but a keyboard.
I think you should disable the retrogame service/program and try - as I suggested before - to make the cabinet gamepad work with the kernel module. However, I think that requires you have the proper wiring to the GPIO as it's described in the project's page. You might have to open the cabinet after all to check for this.

I have the output of /boot/retrogame.conf

# Here's a pin configuration for the PiGRRL 2 project:

LEFT       4  # Joypad left
RIGHT     15  # Joypad right
UP        17  # Joypad up
DOWN      18  # Joypad down
LEFTCTRL  27  # 'A' button
LEFTALT   22  # 'B' button
Z         24  # 'X' button
X         10  # 'Y' button
SPACE      9  # 'Select' button
ENTER     25  # 'Start' button

So I know the wiring now. Could you give me a few pointers how to disable retrogame and if I understand it correctly, move to mk_arcade_joystick for the hardware joystick arcade buttons?

@jp I don't know anything about installing or uninstalling it, since is not part of RetroPie. I suppose it's either a system service that starts it or there's a line in /etc/rc.local that starts it. Looking at their installation howto, I see they're using the /etc/rc.local approach, so you can start there.

jp

I have commented out the line in /etc/rc.local which loads the retrogame binary and I am currently installing the mk_arcade_joystick but got an error with kernelheaders...

https://github.com/recalbox/mk_arcade_joystick_rpi/issues/68

I am so close, if this works I only have to modprobe it with a config:

https://github.com/recalbox/mk_arcade_joystick_rpi#loading-the-driver

sudo modprobe mk_arcade_joystick_rpi map=1 or perhaps custom mapping with the values from the retrogame.conf but will try map=1 first if the kernel-header issue is solved.

mitu

@jp The driver is available from the RetroPie-Setup menu, in the drivers section, try installing it from there (from source) and not directly from the Github repo. After installation, check the module configuration file.

jp

I have had some trouble locating the RetroPie-Setup but I have found that I could access it from ssh:
sudo ~/RetroPie-Setup/retropie_setup.sh
I found the packaging -> driver menu and installed the package, but I saw an error... it was a fast one, but the menu says it did install:

Hope I can configure buttons now for seperate players :-) will see if the reboot fixed everything. I will update this reply with the results.

It did not work. Configuring inputs did only notice the USB controller. Not the hardware buttons. Running sudo modprobe mk_arcade_joystick_rpi map=1 from ssh says: modprobe: FATAL: Module mk_arcade_joystick_rpi not found.

I do see a conf file here: /etc/modprobe.d/mk_arcade_joystick.conf with the modprobe in it. So that part of the install script did run. I also tried to run sudo i2cdetect -y 1 as suggested here https://github.com/recalbox/mk_arcade_joystick_rpi#configuration But i2cdetect is not installed.

Can I see a log of the output of the driver installation from the retropie-menu?

You should find the log files under ~/RetroPie-Setup/logs, they're timestamped with the date when the action was run. If in doubt, clear the folder and re-try your setup action (installing the driver) again.

@mitu thank you once again! I have found the log:

So there are two errors:

Error! There are no instances of module: mk_arcade_joystick_rpi 0.1.5 located in the DKMS tree
Error! echo

and therefor the final error:

FATAL: Module mk_arcade_joystick_rpi not found.
/home/pi

I tried to update it from retropie-setup and got this log. It does not give the instance module error anymore. But does not solve the kernel header issue and also not the module problem:

The problem is that in order to compile the module, you need the Linux kernel headers for the kernel version you're running. You don't have that installed because you probably run rpi-update which updates your kernel + firmware to the testing version distributed by Raspbian, but it doesn't install any kernel headers.
rpi-update is not recommended for regular updates, you should restore the kernel version which is distributed via apt - from the Raspbian repositories - and retry.

jp

@mitu said in Player 2 controller not working:

restore the kernel version

Can't remember running rpi-update but I did apt-get update upgrade etc. some stuff to begin with.
Can I run sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel safely? And will it find the headers then? Sorry to bother you again, but I am a kernel(header)-noob.

mitu

I think it should be fine - see also this post on the Raspberry Pi forums.

jp

IT'S ALIVE! Thank you @mitu! After running the mentioned command and rebooting I ran the retropie-setup again and updated the driver, which worked. Had to do some keymapping in the menu then and it's fixed now!

Next step: make a good retropie backup image of this working setup, because there is no soft shutdown...

mitu

@jp So now both controllers work ?

jp

@mitu yes. since I configured the usb first, the hardware joystick is seen as player 2. But that's okay!

mitu

@jp You can re-order them using the Configuration Editor or the Retropie Joystick selection tool.
Glad you got them working in the end.
