Flashing Om2008.8 rootfs under Windows is *LONG*

It takes me about 20min with a recent quad core system, sp2.  It takes
slightly longer on a linux box with a lighter cpu.

Maybe is mostly dependent on underlying usb.

Hi Abdel,

Actually, the patch is what is compiled into the 0.1+svn beta version of

  dfu-util for Win32 on projects.openmoko.org.  I'm assuming that that 
is the version that everyone here is using?

I also am using WinXP SP2 as Benedikt Schindler on these replies is 
using as well.  For the others who experience long flash times on 
Windows XP, are you also using SP2?

I am using Intel Core2 6420 @ 2.13GHz with 3GB of RAM, and USB 2.0 

I guess the other question is, who else can flash rootfs in under 20 
minutes using dfu-util for Win32?  What are your configurations (version

of Windows (including Service Pack), type of processor, amount of RAM, 
USB controller version)?

Hopefully we can find a commonality among those that experience the long

flash times and among those that do not.
