DFU u-boot patch with beagleboard-xM support

Hi all,

I've been working on loading images into RAM using DFU on the
BeagleBoard-xM. It seemed that there were several bitrotting patches
around. I've merged the best of each into something that works for
me for loading images into RAM on the -xM (but flash support is
broken and untested).

For posterity, attached is a patch against u-boot releases 2010.12
and 2011.03-rc1 (applies to either). It's still not in a clean
enough state for merging into u-boot, but I thought this list may
appreciate it.

I've had to revert to an older version of the musb_udc driver to get
it working, as the one in mainline u-boot seems to have a broken
state machine (which I was able to fix), and did not support High
Speed gadget mode (which I couldn't easily fix).

Thanks also go to Matthew Warton at OK Labs.

Cheers,
Bernard.

Hi Bernard,

How do I make this patch work? My system is a bit different as I am suing overo gumstix so I modified the omap3_overo.h with the lines below:

#define CONFIG_CMD_MTDPARTS /* Enable MTD parts commands /
#define CONFIG_MTD_DEVICE / needed for mtdparts commands */

#define MTDIDS_DEFAULT “nand0=nand”
#define MTDPARTS_DEFAULT “mtdparts=nand:512k(x-loader),”
“1920k(u-boot),128k(u-boot-env),”
“4m(kernel),-(fs)”

/*

  • Board USB Info.
    /
    /     USB */
    #define CONFIG_MUSB_UDC 1
    #define CONFIG_USB_OMAP3 1
    #define CONFIG_TWL4030_USB 1

//#define CONFIG_USB_GADGET 1

/* USB device configuration */
#define CONFIG_USB_DEVICE 1
#define CONFIG_USB_TTY 1

#define CONFIG_USBD_DFU 1
#define CONFIG_USBD_DFU_XFER_SIZE 0x1000
#define CONFIG_USBD_DFU_INTERFACE 2

But still I cannot make it work with the dfu-util. he device is already being detected as Netchip U-boot 2011.12 by my Linux machine. But running dfu-util gives the logs below and no extra logs in u-boot console. Am I missing any step?

$ dfu-util -l

dfu-util does currently only support DFU version 1.0

Thanks and best regards,
