Hi，Denis: This SOC is not opened. It’s our new chip(Digital Base Band) designed for TD-SCDMA mobile. I’m not clear for DFU, but I think it’s same, you need write a low level usb device driver in /driver/usb, and write a DFU client level over it. Because U-Boot support TFTP and Linux PC support USB-CDC ，so I needn’t care about host side, but you may need to do something in host side.

HI Gong: One question: is that _SOC_ open? I'm personally interested in your USB-CDC implenmentation. And currently I'm trying to add DFU support for Beagleboard (TI OMAP3) which is also base on U-boot usb gadget. May quite similar to your work. Oh, I only doing that slowly at my spare time, just a hobby :_) Hope you can shine some lights on me. Thank you.
Dennis 2009/3/9 龚益斌 gongyibin@leadcoretech.com Hi，all, I’m am new guy from China, and nice to meet all of yours. These days we use u-boot in out Linux Project base on our SOC chip, and we found it’s not convenient to download kernel image because our board have no ether-net chip, only USB and UART. Linux-2.6.21 etc, support USB CDC subnet(Boot Loader OBject), so if we write a USB device driver and a virtual Ethernet card driver over it , we can realize TFTP download with USB. Now we have test successfully in our project, if necessary I’m very glad to contribute it~ Regards, Gongyibin
