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 ~Sumit Gemini

Hi All,

 I am trying to upload images from dfu devices to PC, but

"Copying data from DFU device to PC Starting upload: [] finished! Received a total of 1 bytes"

error i got,

do not know why i getting this kind of error because downloading of files is made but uploading not.

Any help will appreciate.

"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 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

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