AM335x "USB Device Not Recognised" when connected to Windows XP.

John Murphy1
Expert 1210 points

Hi,

I've got a brand new fresh AM335x EVM with the stock free SD card (labelled "AM335x EVM Linux SDK v5.04.01", which is running Linux 3.2.0.

root@am335x-evm:~# uname -a
Linux am335x-evm 3.2.0 #1 Mon Apr 9 10:19:16 CDT 2012 armv7l unknown

When I boot up the AM335x EVM, and then after boot up is complete, connect the USB cable from the AM335x EVM to my PC, the "BeagleBone (D:)" window appears on Windows XP as expected.

When I connect the USB cable first, and then turn on the AM335x EVM, I get a "USB Device Not Recognised" bubble notification in Windows XP, and the "BeagleBone (D:)" window and drive does not appear unless I disconnect and reconnect the USB cable.

I would like the gadget MSD work in both bootup / cable scenarios for my AM335x based product.

    The issue sounds that same as the one mentioned near the end of this thread:

    I've tested this on the same PC, booting into Linux (KUbuntu 12.04.1) instead of Windows XP.

    If I turn on the AM335x EVM first, and then connect the cable, the BeagleBone drive appears ok.

    If I connect the cable first, and then turn on the AM335x EVM, it does not work unless I disconnect and reconnect the USB cable.

    The dmesg log on the PC shows the following for the failure case:

    This seems to be fixed in Arago v3.2-staging, if configured with CONFIG_USB_GADGET=m.

    git clone http://arago-project.org/git/projects/linux-am33x.git

    git checkout -b v3.2-staging origin/v3.2-staging

    Build kernel (nb: configured CONFIG_USB_GADGET=m in menuconfig):

    export PATH=/home/johnmu/ti-sdk-am335x-evm-05.05.00.00/linux-devkit/bin/:$PATH

    make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm am335x_evm_defconfig
    make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm menuconfig
    make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm uImage
    make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm modules

    Then modify  /etc/init.d/storage-gadget-init to load ti81xx module before MSD gadget:

    modprobe ti81xx; modprobe g_mass_storage file=/dev/mmcblk0p1,/dev/mmcblk0p3
