Hi Lukasz,
My dfu version is 1.0 and am using SPI flash NOR. downloading is fine
but uploading failed.
I am trying lot to upload binary from dfu-device to pc but not able to
do that.
I am facing following error :-
when i apply
dfu-util -v -a u-boot -U dfu-UBOOT 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.
Any help will appreciate and if any body has related pointer, please let me
know, I have stuck in this error.
and further more,
After analyzing a lot, i got a function "dfu_upload" in dfu.c file, calling
another function "libusb_control_transfer" which return only 1, might be it
is not getting interface, because when i pass
dfu-util -a u-boot -U SPL-uboot in host machine
i got in target machine :-
SF: Detected N25Q256 with page size 64 KiB, total 32 MiB
Running: sf read 0x00000000 0x20000 0x0
Failed to map physical memory
So, how can i analyze flash memory, why it is getting fail to map itself
with physical memory.
Thanks
