"man dfu-util" says:

      -U, --upload FILE
              Read firmware from device into FILE.

              Note: Upload support is currently broken.

Maybe you find more help here:

HI Heiko,

     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

Thanks

There is no DFU-SPI glue in mainline.  Please post the patches you have
for adding SPI support to DFU, or contact your vendor.

[U-Boot] Not abled to upload binary using "dfu-util"

[Sumit Gemini]

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
