Loading GPIO Joystick drivers on startup

[fh1105]

I'm using GPIO Joysticks – when I load the driver after connecting via SSH to my Recalbox, I can load the driver:

mk_arcade_joystick_rpi map=1,2

After that, the joysticks work perfectly.

However, after rebooting, the driver is gone – unsurprisingly, as it isn't loaded on startup. I'd like to change that.

Unfortunately, this tutorial

https://github.com/recalbox/mk_arcade_joystick_rpi

doesn't do the trick for me. It does, for instance, assume

sudo 

to exist on the system (which isn't the case for Recalbox), and also I do have the feeling that I'm stuck in 'read only' mode after ssh'ing to the system.

Any ideas are welcome! Thank you.

I did manage to mount the SD card of my RPi 3 in writeable mode add

mk_arcade_joystick_rpi

to

/etc/modules

and

options mk_arcade_joystick_rpi map=1,2

to

/etc/modprobe.d/mk_arcade_joystick.conf

. – but still the drivers do not load on startup. When I run

mk_arcade_joystick_rpi map=1,2

manually after start-up, it works –but it doesn't do that automatically. Any help would be appreciated. Thank you!

@fh1105 Read this, it may be out of date, but it should help with something:

Yes, these are exactly the steps I took ("Automatic loading at startup").

How can I run a script upon booting Recalbox?

@fh1105 Did you enable GPIO controllers in the recalbox.conf file?

# ------------ D2 - GPIO Controllers ------------ #
## GPIO Controllers
## enable controllers on GPIO with mk_arcarde_joystick_rpi (0,1)
controllers.gpio.enabled=0
## mk_gpio arguments, map=1 for one controller, map=1,2 for 2 (map=1,map=1,2)
controllers.gpio.args=map=1,2
## Custom mk_gpio arguments,
## controllers.gpio.args=map=5 gpio=Y-,Y+,X-,X+,start,select,a,b,tr,y,x,tl,hk  for one controller,
## controllers.gpio.args=map=5 gpio=pin1,pin2,pin3,.....,pin12,pin13
## controllers.gpio.args=map=5,6 gpio=Y-,Y+,X-,X+,start,select,a,b,tr,y,x,tl,hk gpio2=Y-,Y+,X-,X+,start,select,a,b,tr,y,x,tl,hk for 2 (map=5,map=5,6)

## Set pin to -1 to disable it

## MCP configuration : GPIO and MCP can be used together. You can mix them.
## map=0x20,0x21 for 2 mcp23017 on i2c bus
#controllers.gpio.args=map=0x20,0x21,5,6 gpio=4,17,27,22,10,9,25,24,23,18,15,14,-1 gpio2=11,5,6,13,19,26,21,20,16,12,7,8,-1

To start a script automatically with Recalbox, this is the tutorial, but I don't know if that's what you need:

That solved it for me – I set it to GPIO enabled = 1 in the .conf file. Thank you very much, keep it up!
