Re: [U-Boot] [PATCH 2/4] arm:goni:dfu Add support for DFU at GONI target

25 Jun 2013

Hi Lukasz,
sorry i just copy and paste that...
"why dfu-SPL? Not dfu-BOOT"
dfu-Boot will come instead of dfu-SPL
and thanks for help, i talk to Pantelis, Heiko for the same.
Thanks & Regards

Hi Sumit,

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.
Why dfu-SPL? Not dfu-BOOT? (you are calling the dfu-util command with
-U dfu-UBOOT)
...
but on target machine, i got
Running: sf read 0x00000000 0x20000 0x0
Failed to map physical memory.
I'm not the right person to answer. You ought to ask Tom Rini or
other developers involved in flash development (e.g. Pantelis, Heiko).
...
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.
What I can do is to check if the USB gadget DFU layer works with
upload. With the NAND backend I'm not able to help much here (I don't
have NAND memory on my targets).
...
Thanks

Hi Lukasz,
  I put the dfu support into am335x board even i able to

download all images from dfu-util, but when i trying to upload
images, (from dfu devices to PC), my system failed.
Could you tell me what is the problem and where should i look
into?
Indeed dfu upload doesn't work on Trats anymore (it uses eMMC
backend). I've checked and fixed problem with dfu write yesterday
(also with eMMC).
Recently the dfu subsystem has been reworked to get rid of fixed
buffer size, so please regard it as "under heavy development".
I will look into this problem (for eMMC, not NAND - since my Trats
doesn't have NAND memory).
BTW: Which version of dfu-util do you use? (Mine is 0.5, but for
debian 5.0 / 6.0 there also was very ancient 0.1 version - which
doesn't work with current dfu code).
...
Thanks & Regards

From: Arkadiusz Wlodarczyk a.wlodarczyk@samsung.com
Proper adjustment for supporting DFU at GONI target has been
made. The s5p_goni.h file has been updated. Moreover the code
for low level USB initialization has been added to GONI board
code.
