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
