Udoo Neo Full not detecting any joysticks with SDL2 / UDOObuntu 2.1.2

Ok so I switched to dummy driver and this time I got this. Still wondering why frame buffer was not detected (separate issue)

udooer@udooneo:~/github/jstest-sdl$ SDL_VIDEODRIVER=dummy ./jstest-sdl --list
No joysticks were found
udooer@udooneo:~/github/jstest-sdl$ ls -l /dev/input/
by-id/ event0 event2 event4 js1 js3
by-path/ event1 event3 js0 js2 mice

 

I was just informed on IRC SDL channel that SDL2 does not use jsX. It was used in SDL1. Now SDL2 is using udev/evdev.
Is there a module that needs to be build or some rule added?

 

You need to add some udev rules for your joystick:

First find the ID_VENDOR and ID_MODEL of the joystick (change jsX) eg:

Code:

udevadm info -q all -n /dev/input/js0

create a udev rule file in /etc/udev/rules.d/73-presistent-joystick.rules

Add an entry for the your ID_VENDOR and ID_MODEL eg:

Code:

KERNEL=="js?", ENV{ID_VENDOR}=="YOUR ID VENDOR", ENV{ID_MODEL}=="YOUR ID MODEL" , NAME="input/js0"

 

Below is info for each jsX. I also added /etc/udev/rules.d/73-presistent-joystick.rules

KERNEL=="js?", ENV{ID_VENDOR}=="046d", ENV{ID_MODEL}=="c219" , NAME="input/js0"

After rebooting and plugging my usb joystick It still it is listed as js3. Doing cat js3 and pressing buttons on joystick I get some echo on screen.

After removing joystick and rebooting udoo board I see that after adding rule I do not see any jsX in /dev/input/

udooer@udooneo:~$ ls -l /dev/input/

After plugging in joystick I do get all four js with still js3 as my joystick and event4 added

You need a line like this:

Code:

KERNEL=="js?", ENV{ID_VENDOR}=="Logitech", ENV{ID_MODEL}=="Logitech_Cordless_RumblePad_2" , NAME="input/js3"

 

Typo should be:

Code:

KERNEL=="js?", ENV{ID_VENDOR}=="Logitech", ENV{ID_MODEL}=="Logitech_Cordless_RumblePad_2" , NAME="input/js0"

[/QUOTE]

 

jas-mx

I did updated my rule to
KERNEL=="js?", ENV{ID_VENDOR}=="Logitech", ENV{ID_MODEL}=="Logitech_Cordless_RumblePad_2" , NAME="input/js0"

after board and plugging in joystick I get data updates on js3 not on js0

Looks like accelerometer is going before it

I think these are the guys js0-js2

udooer@udooneo:/sensors$ ls -l

lrwxrwxrwx 1 root root 38 Jul 18 12:14 magnetometer -> /sys/class/misc/FreescaleMagnetometer/

Also from dmesg

[ 7.660400] input: FreescaleMagnetometer as /devices/virtual/input/input3

Could they be remaped to other js or disabled since I am not using them at the moment?

 

The udev rule should have replaced js0 with your joystick so you will need to debug why its not working. If you want to disable the acclerometer/gyroscope then you need to disable then from the dts file or create udev rules to stop them being mapped.

 

I will look into disabling it in udev. Could you also expand on "debugging" Where would you start and what to look for as a start point?
Anything you can think of. I will try to find what the issue might be. I never done this so it is great time to learn.
Thank you
