GPIO controller (nes)

jthemad

Hi!! I'm using batocera 5.7 on pi3 and I notice that my Nes controllers connected by GPIO pins don't work anymore. Before batocera I used recalbox 4.0 and the controllers worked.. I copy the same string from recalbox.conf and if I scroll the controller in the controller menu I can 'see' #2 NESPAD and #3NESPAD, so the config file is ok.. but the pads don't work, neither in the emulation station menu. With recalbox 4.0 they worked, menu and games. The hardware is the same.. can anyone help me? Thanks @nadenislamarre

nadenislamarre

can you do a report please ?
you should remain more than 1 minute on the irc each time ;-)

What do you mean? I connect my nes pad (I have a genuine nes mod by myself with genuine Nintendo controllers connected by GPIO to the pi3 inside the nes. Before batocera I used recalbox and it worked.. now the controllers doesn't work (game or ES menu), but I can see the NESPAD in the input menu

run /recalbox/scripts/recalbox-support.sh when the pad is plugged to have some information

Hi @nadenislamarre , this is the support file, with the NES pad connected by GPIO. I can see it in input menu of batocera #2NESPAD and #3NESPAD, but it doesn't work, ES menu or game doesn't work.. I Tested and used it in recalbox 4.0.1, same config string in recalbox.conf and same hardware.. could you help me please? Thanks all

ok. the pad looks here.
can you type in ssh : "evtest", choose your pad and check if the events are seen by linux ?

jthemad

@nadenislamarre ok, just test.. if I chose controller 0 (generic wireless pad), all works (I see string on ssh evrytime I press a button). If I choose the controllers 1 or 2 (NES pads in my config) nothing happens, like they are not connected..

@nadenislamarre hi! Did you found something wrong? Tested with recalbox 4.0.1 working.. batocera 5.1 not working. Batocera 5.8 not working.. let me know if I can test something.. see you!

Hi! I was reading the recalbox forum looking for a solution for the nes controller problem in Batocera. I noticed in the recalbox 4.1 unstable changelog this line:
-Updated gamecon driver from 1.0 to 1.2
And then
-fix gamecon 1.2
https://archive.recalbox.com/updates/v1.0/unstable/rpi3/recalbox.changelog

I remember that you were in the recalbox team since 4.1, maybe there is a problem in the gamecon driver 1.2 (that is used for nes/snes controllers)..
can I test the gamecon 1.0 driver? Could it be the right way? Need help/instruction for test this thing...
Thanks a lot @nadenislamarre

@jthemad please found here the built files https://batocera-linux.xorhub.com/special/lib/
hi think that just https://batocera-linux.xorhub.com/special/lib/modules/4.9.13-v7/extra/gamecon_gpio_rpi.ko
is enough.
copy it on your card.
$ rmmod gamecon_gpio_rpi
to remove the current driver
$ insmod gamecon_gpio_rpi.ko
to load this one. and test.
i'm not sure you can copy it directly in /lib/modules/4.9.13-v7/extra while i guess that it may change dependancies. if needed, i can build a new image for you.

nadenislamarre

i've done and send an image here : https://batocera-linux.xorhub.com/special/lib/boot.tar.xz

jthemad

nadenislamarre thank you very much!! I'm not at home now tomorrow evening I'll try it and then feedback to you on irc/forum! Is it for rpi3? Is the link up? Can't open it..

jthemad

@nadenislamarre hi naden, I don't understand what I have to do with the .xz file.. is it an image or have I to unzip and copy/replace on my sd card? Thanks

nadenislamarre

see https://batocera-linux.xorhub.com/wiki/doku.php?id=en:upgrade_manually

yes. or by command line, it's easier :
/recalbox/scripts/recalbox-upgrade.sh https://batocera-linux.xorhub.com/special/lib

it will download the boot.tar.xz inside, compute the md5sum if found inside (not found in this case while i've not done it), and unzip it on your sd card. Just reboot after that.

nadenislamarre hi naden! I've just done everything but no luck... after a restart the nes pads still don't work.. I notice that batocera alerts me that there is un upgrade avaible, but I am using 5.8.. is it correct? Is there something I can do for the nes pads now? Thank you

nadenislamarre

the upgrade is normal. batocera detects that the version you have is not the last one available. (it's not based on the version number, but on the content of the firmware)

jthemad

nadenislamarre ok.. so we are at dead point...

nadenislamarre

yes. however, my only guess is that it may come from an upgrade of linux.
have you ask on the forum on the gpio driver side to see if something changed in the last versions of linux ?
