Cover letter [U-Boot] [PATCH v2 0/7] dfu:usb: Composite USB download gadget with DFU function
Quoted 39 lines · Lukasz Majewski

Hi Marek,

Quoted 26 lines

Those patches add support for composite USB download gadget. This gadget (at least for now) is equipped with DFU download function.

A separate DFU back-end and front-end have been added. Back-end is placed at ./drivers/dfu directory. The front-end is implemented as USB function.

The back-end is written in a generic manner with storage device specific code separated (eMMC).

DFU specification can be found at:
http://wiki.openmoko.org/wiki/USB_DFU_-_The_USB_Device_Firmware_Upgrade_standard

Example usage:

u-boot side: dfu mmc 0
PC: dfu-util -U IMAGE.bin -a uImage (for upload)
dfu-util -D uImage -a uImage (download)

To list the alt settings:
dfu mmc 0 list

Test HW:
Exynos4210 Trats board

Do you have more comments about those patches?

I _think_ he's been busy with exams and preparing for the U-Boot BoF this week. I'll make sure this gets brought up then however.
