Player 2 controller not working

mitu

@jp OK, thanks for coming back with the info. So the problem, as I understand better now since you added the info about controllers, is that

P1 is the gamepad built into the cabinet
P2 should be the PS3 controller
P2 is acting as P1, overriding the P1 buttons and joysticks.

Your postings so far show only 1 gamepad configured (DragonRise Inc. Generic USB Joystick.cfg) in /opt/retropie/configs/all/retroarch-joypads, which I assume is the PS3 controller (?), but they don't show the configuration file for the cabinet's gamepad. Normally, there should have been also an additional .cfg file for the built in gamepad.

Your problem looks like you'd have the same device name (DragonRise ..) for both gamepads, but if you're using the GPIO connections for the cabinet gamepad, its name should be different.

To list the available gamepad/inputs/joysticks detected, run cat /proc/bus/input/devices and it should list all input devices.
To see how many joysticks are detected, run a ls /dev/input/js* and - if 2 gamepads are detected - there should be at least 2 entries for js0 and js1. You can test how they're responding to buttons/joypads using jstest /dev/input/jsX (see this section of the RetroArch controller configuration).
Lastly, you can enable verbose logging in RetroArch via the Runcommand launch menu and then post the log file created after launching a game - /dev/shm/runcommand.log - on pastebin.com. This should show how many gamepads RetroArch detects and what configuration applies to them.

Thank you @mitu for your reply. Your bullet list is accurate!
I have the output of the two commands:

pi@retropie:/opt/retropie/configs/all/retroarch-joypads $ cat /proc/bus/input/devices

pi@retropie:/opt/retropie/configs/all/retroarch-joypads $ ls /dev/input/js*
/dev/input/js0

So the hardwired (to the GPIO) joystick is not listed. Only the ps3 controller. The strange thing is that it did work before. So an update broke it.
I might have found it by reading the used guide:

https://github.com/recalbox/mk_arcade_joystick_rpi#auto-load-at-startup

There it says to make a conf file, but when I open the conf file in nano, it's empty.
So jstest /dev/input/js0 shows the usb ps3 controller...

I have no knowledge about mk_arcade_joystick_rpi but it seems to me that there is an error because of the empty configuration file but somehow the joystick does work great????

empty file:
sudo nano /etc/modprobe.d/mk_arcade_joystick.conf
another empty file:
sudo nano /etc/modprobe.d/raspi-blacklist.conf

it even seems that there is no mk-arcade* package installed:

pi@retropie:/opt/retropie/configs/all/retroarch-joypads $ dpkg -s mk
mk-configure    mkgmap          mklibs          mknfonts.tool   mktemp          mkvtoolnix
mkcue           mkgmapgui       mklibs-copy     mksh            mktorrent       mkvtoolnix-gui

is the 'tab' autocomplete output...

However, I did find an xpad-0.4 in /usr/src/ which links to /opt/retropie/supplementary/xpad
I will try to dig more.

in sudo nano /etc/modules
there is just one line: uinput

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?

mitu

@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?

mitu

@jp said in Player 2 controller not working:

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.

jp

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

So there are two errors:

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.
