USB Gadget ConfigFS in VOXL



  • I am trying to get the VOXL dev board to act as a HID device.

    I am trying to use the USB gadget feature of ConfigFS.

    As far as I can tell it doesn't look like the yocto build has this compiled in the Kernel.

    I was just wondering if I have missed something or I should look into the VOXL Open Source Kernel Build

    Hi @Thomas-MacNamara ,

    You're likely correct (not enabled). Let me double check our flags, and also what limitations you'd hit with the open source kernel build if any (where you could modify what you needed).



  • Thanks mate that would be greatly appreciated!

    Hey @Thomas-MacNamara,

    Sorry for the lag, I'm new to the USB gadget, but here's some flags found on VOXL from our standard kernel, from adb shell zcat /proc/config.gz

    # CONFIG_USB_DWC3_GADGET is not set
    CONFIG_USB_GADGET=y
    # CONFIG_USB_GADGET_DEBUG is not set
    CONFIG_USB_GADGET_DEBUG_FILES=y
    CONFIG_USB_GADGET_DEBUG_FS=y
    CONFIG_USB_GADGET_VBUS_DRAW=500
    CONFIG_USB_GADGET_STORAGE_NUM_BUFFERS=4
    # CONFIG_USB_GADGET_XILINX is not set
    # CONFIG_USB_GADGETFS is not set
    # CONFIG_USB_MIDI_GADGET is not set
    

    I'm guessing the actually functionality isn't there though?
