@truha i hope you speak english

So you've activated i2c, but it's not working / crashing ? Are you US ng the mk_arcade_gpio module ? On my side i've veen working on merging the master branch in the hotkey branch, i could test i2c and it was working fine. Still not available in recalbox though

[TRuHa]

@substring Yes, it works! at the beginning it gave me a bit of war when compiling, but in the end I got it. I only have the problem that the buttons are exchanged for the PAD but it does not cause me any problems.

The problem I have with the update, that when I update the i2c stops working and I have to reinstall everything.

I use the traditional method in the menu of the recalbox interface. When it restarts, it only shows me a black screen with many errors and it dies. I do not have access to the system through HTTP or SSH.

[Substring]

@truha ok. Between which versions does it stop working ? what are your edits ?

[TRuHa]

@substring I compiled the system using this manual:

https://gitlab.com/recalbox/recalbox/wikis/compilation-process

The only change you made is to enable i2c in mk_arcade_joystick_rpi.

I currently use version 4.10

When I configured the WiFi connection I was notified of a new update, I do not know the version exactly.

[Substring]

@truha still, i don't get how you use i2c ... do you enable the gpio controllers through i2c ?

[TRuHa]

@substring First I modify with make menuconfig to enable i2c:

Then I modify mk_arcade_joystick_rpi.c to be able to use the necessary buttons:

Compile the system and load the image in the microSD.

Edit /etc/modules.conf and add at the end of the file:

i2c-bcm2708
i2c-dev

Edit the /boot/config.txt and add following lines in it:

#Activate I2C
dtparam=i2c1=on
dtparam=i2c_arm=on

Edit the /boot/cmdline.txt and add at the end of line:

bcm2708.vc_i2c_override=1

I set the i2c address in recalbox.conf with the address obtained with i2cdetect -y 1:

controllers.gpio.enabled=1
controllers.gpio.args=map=0x20

At this point it is when I set up the WiFi connection, it notifies me that there is a new update and when executing it it breaks my system.

@truha Ifnyou made some edits yourself, of course an upgrade will break it ! The whole system is upgraded, even the module you.ve edited ! Just reinstall the ko and you're good

[TRuHa]

@substring you mean you re-download and compile?

Thank you very much for the help.
A greeting.

[Substring]

@truha No ! I mean simply reinstall your version of mk_arcade_joystick_rpi.ko
