Hi Tom,
Thanks for reply and need more help...
on host machine i can easily see the all partition by applying "dfu-util -l". and i am able to download images from pc to dfu-devices and it running fine, but in case of uploading (from dfu-device to PC), my system just copied only 1 byte data, and said uploading finished.
i stuck here, even i am not getting where is error. and yes when i applied
on host machine : dfu-util -a u-boot -U DFU-UBOOT
Got this output on host machine:-
bytes_per_hash=4096 Copying data from DFU device to PC Starting upload: [] finished!
and file DFU-UBOOT created with 4KB size.
on target machine got such output :
Running: sf read 0x00000000 0x20000 0x0 Failed to map physical memory.
here 0x20000 is my u-boot base address.
and sorry for saying i am very new in this DFU, i got complete source code from client and i already check dfu source code even there is a entry for dfu usb gadget in board file(am335x.h).
so now what should i verify regarding dfu. if you want i can send you my board file.
Thanks ~Sumit Gemini

Thanks for reply and for links, i raised a request for membership. Here I want to share regarding dfu, when i apply dfu-util -v -a SPL -U dfu-SPL from my host machine,I got such log on Host machine :-
Device returned transfer size 4096 bytes_per_hash=4096 Copying data from DFU device to PC Starting upload: [] finished! Received a total of 1 bytes
and finally dfu-SPL file created with 4kb size.
but on target machine, i got
Running: sf read 0x00000000 0x20000 0x0 Failed to map physical memory.
May i know why i got such error or user have to specify address over
which
we read our binary
There is no DFU-SPI glue in mainline. Please post the patches you have for adding SPI support to DFU, or contact your vendor.
