Error after updating retropie-setup to 4.4.9 (a161774a)

  • After updating retropie-setup to 4.4.9 (a161774a) I get this error:

    pi@raspberry: ~-RetroPie-Setup_001.png

    I'm using a Virtual Machine with PIXEL, if that's helpful.

  • @hiulit
    I have this too!
    After update cores and sixaxishelper I didn't know what caused it.
    It only happens when I connect a Wii controller to bluetooth, PS3 controller okay, logitech okay.

    My device

    • Raspberry Pi 3 B+ same retropie version.

    @hiulit What controller/keyboards do you have configured on this system ?

  • @mitu None that I know of. It's a Virtual Machine running PIXEL, so I guess I only have a keyboard.

  • @hiulit
    What virtual machine? Linux could pass through anything on your system to the vm.
    Like I said before, I had the exact same error, thrown across my screen, line numbers and everything, though it was thrown with a slightly different pattern more horizontally skewed, probably the screen resolution.

  • cat /proc/bus/input/devicesin the vm, I think that is what mitu told me.

    @hiulit I also have a similar setup (albeit running Ubuntu) in a VM and I don't get this message. But it's definitely something that's changed in the RetroPie's side.
    Can you check to see if you have any configuration files (for a gamepad) in the /opt/retropie/configs/all/retroarch-joypads folder ?

  • Global Moderator

    Nevermind, I managed to reproduce the error. It seems that the update to joy2key might have something to do with it.
    @psyke83 Can you take a look at the error reported by @hiulit ?
    I get the same error on a stock RetroPie 4.4, installed from scratch and updated to the latest master. Started raspi-config, got the error and the gamepad doesn't work.
    If i revert to 6ebb8150 then the error is gone.
    I only have 1 gamepad configured (USB,2-axis 8-button gamepad .cfg) in /opt/retropie/configs/all/retroarch-joypads)

    input_device = "USB,2-axis 8-button gamepad  "
    input_driver = "udev"
    input_l_btn = "4"
    input_load_state_btn = "4"
    input_start_btn = "7"
    input_exit_emulator_btn = "7"
    input_down_axis = "+1"
    input_r_btn = "5"
    input_save_state_btn = "5"
    input_right_axis = "+0"
    input_state_slot_increase_axis = "+0"
    input_select_btn = "6"
    input_left_axis = "-0"
    input_state_slot_decrease_axis = "-0"
    input_up_axis = "-1"
    input_a_btn = "0"
    input_b_btn = "1"
    input_reset_btn = "1"
    input_enable_hotkey_btn = "6"
    input_x_btn = "2"
    input_menu_toggle_btn = "2"
    input_y_btn = "3"

    Everything else is the default on a RetroPie 4.4 image.

  • @mitu Doesn't the error say index out of range? My Wii controller threw it and it has like 4 configurations(accelerometer, IR, controller, blah) but only 6 buttons on the js1 and it doesnt work. Are the buttons out of range? is there really 8 buttons on the js0?

    But I mostly agree, I didn't get this pre-update, although I never got a chance to use the wii controller, because the PS3 driver used to kick it off before it could sync.

    @Efriim I don't think it's specific to the controller used. I don't get an error if the autoconfig folder is empty - on my Ubuntu test machine for instance, where only a keyboard is used.
    For the PS3 one, remove the ps3driver and install the sibling sixaxis driver. This uses the Linux BT stack and it will allow you to pair and register other BT controllers - like the Wii controller.

  • I synced the wii controller again, triggering joy2key in retropie menu triggers the error.
    I don't have a Nintendo Wii config in /opt/retropie/configs/all/retroarch-joypads, I emptied the directory, and I still get the error. Only when the wii controller is connected.

    Do you know what folder joy2key references for fds file descriptors? other than /dev/input/

  • Global Moderator

    @Efriim Well, let's take it one step at a time. If you want to get rid of the error in this topic, checkout a later revision of the RetroPie-Setup script

    cd $HOME/RetroPie-Setup
    git checkout 6ebb8150

    then take it on from here.
    To revert to the normal RetroPie-Setup branch (once the error in this topic is resolved), just run

    cd $HOME/RetroPie-Setup
    git checkout master

    Thanks for letting me know @mitu. It looks like your config is not being detected and falls back to the main retroarch config which doesn't have any mappings. Will work on a fix soon.

  • Global Moderator

    Please let me know if this fixes the issue:

    @mitu - although I'm confident the above will resolve the errors, I think that we might have highlighted the issue that joy2key (even when reverted to the commit you specified) isn't utilizing your mappings for that controller correctly, and falling back to retroarch.cfg instead. I can try to troubleshoot that in more detail if you can confirm that my suspicion is correct.

    You said that you only have one gamepad configured; the error triggers if an unconfigured or partially mapped controller is connected, so if you also had a different, unmapped controller connected, then the script doesn't need any further fixing beyond the current PR.

  • Global Moderator

    @psyke83 The PR seems to work, thank you.

    Indeed, I have 3 /dev/input/jsX devices present, but only 1 of them was configured - the one I mentioned (USB,2-axis 8-button gamepad , mapped to /dev/input/js0). The configuration was done from Emulationstation, without any other external edits.

    There's one more message (probably related to the signal handling updates for joy2key) that appears now every time joy2key starts

    Exception OSError: (9, 'Bad file descriptor') in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored

    It stays in the background (doesn't clutter the dialog boxes), but it doesn't appeared before. Also reported here.

    Thank you. We can debug further if you like, so let me know if you want to be to test other things.

    Unfortunately I can't reproduce this error. Can you isolate whether it's triggered by a specific controller in particular? I only have two PS3 controllers, and I can't trigger the error with none, one or both connected.

    @psyke83 said in Error after updating retropie-setup to 4.4.9 (a161774a):

    Unfortunately I can't reproduce this error. Can you isolate whether it's triggered by a specific controller in particular?

    I use only 1 controller (the one I mentioned), though there are 3 /dev/input/jsX entries from the other 2 controllers. If I unplug the other 2 controllers (which actually it's just a 2SNES-to-USB adapter without any controllers connected), I still get the same Exception OSError: (9, 'Bad file descriptor') ..., so it doesn't look like it's related to a particular controller.
    I'm on a fully updated Raspbian Stretch, maybe there's something from a package update.

    I tried (on the master branch) to reproduce the original error (the one reported by @hiulit) without the other 2 controllers connected and it seems ok - the problem appears only when I have the other (un-configured) 2 controllers connected.

    Would it be possible for you to isolate the part of the script triggering the warning via some manual edits? See:

    In the three instances where I replaced except: with a more specific exception, you could change one back to a naked exception and see if it eliminates the warning. If I could at least know which one of the three is the trigger, it should help me evaluate the exact origin of the error. Thanks!

    Line 163.
    OSError and ValueError both throw exceptions individually, if one of them is a parent, probably ValueError.

    @psyke83 thanks, I'll do some testing tonight, don't have access right now to the system.
