in UP Squared Linux
Hi,

Does the UP Squared support USB3.0 OTG port in device mode? Wiki [1] says it supports only on UP , so I am just wondering what's the status on UP Squared.

Thanks

    Hi, can you please confirm that current version of Up Squared is supporting USB OTG device mode ?
    I'm interested in impersonating USB storage device and/or HID devices in Ubuntu.

    Thank you.

    Hi raresh_p,

    USB OTG should be supported on UP2 from BIOS V2.1 onwards. See:

    Thank you for your comment, based on this I have ordered an UP Board.
    While in basic tests seemed to work with memtest ISOs (mounting it then having it available as USB Flash on Win 10 laptop) , now I have the "UDC error" :
    udc-core: couldn't find an available UDC - added [g_mass_storage] to list of pending drivers

    Is there any description how to specifically debug this and even check if the hardware is working ok?
    Or even how the BIOS setting should look in order to use UP Board as USB Device ?

    PS: Forgot to mention, I have the UP Board version with 2Gb memory and 16GB eMMC disk.

    Thank you.

    Hi @raresh_p ,

    Did you get that error when you connect your UP to your PC via USB OTG port, right?

    To be sure your OTG is working you must check in your PC if the board is available.

    Use dmesg | tail for example.
    You should see something like that:

    [48794.482729] usb 2-2: SerialNumber: 012345678

    Hello ,
    I have the Up squared 8GB memory / 64 GB storage version.

    Problem: Windows 10 shows "Device malfunction, Could not recognize" when plugged in the Up squared board through otg.

    Steps: Following steps are performed to use up-squared as gadget mass storage device and to access it from windows 10

    1 In bios the OTG device mode is already enabled.

    2 In terminal , I ran following commands,
    dd bs=1M count=4 if=/dev/zero of=gadget_storage
    fdisk -u gadget_storage
    * pressed "x" for expert mode
    * pressed "s" and entered 8 for 8 sectors
    * pressed "h" and entered 1 for 1 head
    * pressed "c" and entered 1024 for 1024 cylinders
    * pressed "r" to get out of xpert mode
    * pressed "n" and then "p" for primary
    * Entered the default value to select the partitions and then First sector and Last sectors
    * pressed "t" and and pressed "7" to select file system as NTFS
    * pressed "w" to save the partition table.
    losetup -o512 /dev/loop0 gadget_storage
    *// -o 512 setting the byte offset (First sector number[1 in my case] * 512 = 512)
    mkfs.ntfs -p 1 -S 8 -H 1 /dev/loop0 8191
    *// p sets starting sector number which is 1 , S represent sectors per track which i selected as 8 , H as heads and 8191
    *// reperesent total sectors .
    losetup -d /dev/loop0
    *// detaching the backing store file from loop device
    modprobe g_mass_storage stall=0 file=gadget_storage

    1. Connected the upsquared to windows 10 host machine while OTG cable

    Problem : windows 10 shows , Device malfunctioned , could not recognize the usb device.

    However , I could successfully detect the mass storage in windows 7 and linux ubuntu host systems ,

    Could somebody please help me understand what could go wrong with windows 10.

    Thank you
