Wifi Shield firmware update fails at blank check

Hello

I am trying to update the Firmware on Wifi Shield.

As per instruction on http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading, I download the flip application from Ateml website for windows. I am running on Windows XP. Flip version 3.4.7.

When I run the batchisp.exe command, the blank check error fails.
The command I used is:

batchisp.exe -device AT32UC3A1256 -hardware usb -operation erase f memory flash blankcheck loadbuffer C:\Documents and Settings\syoganathan\My Documents\Downloads\wifiHD.elf program verify start reset 0

Here is the result of the command:

Running batchisp 1.2.5 on Thu Apr 04 12:25:49 2013

AT32UC3A1256 - USB - USB/DFU

Device selection....................... PASS
Hardware selection..................... PASS
Opening port........................... PASS
Reading Bootloader version............. PASS 1.0.2
Erasing................................ PASS
Selecting FLASH........................ PASS
Blank checking......................... PASS 0x00000 0x3ffffFAIL Invalid or missing argument.

ISP done.

What could be causing the blank check to fail? Any Idea?

Issue is resolved. I did not quote the path for the elf file

Hello!, I have the same issue with my Wifi Shield. I tried with a quoted path but ir doesn't works. Can you sow me how you wrote it?.

Thanks!

The example shows this path to the needed files. Insure that path is correct. If not, change it.
/Arduino/hardware/arduino/firmware/wifishield/binary/
That was not the correct path to access those files in my computer.

edit: This part was correct, but the part preceding this was incorrect.
/hardware/arduino/firmware/wifishield/binary/

Thanks!,

There was an "s" in "firmwares" in my path. Now it works!.
