Hi Mike,
I just went through these steps a few days ago and found out that the
problem is with cygwin. It is actually a FAQ (sorry I don't have the
reference)
I circumvented the problem by using a win utility called rawwritewin that I
found on the net instead of dd and it worked just fine.

You might want to find another one for XP though.
Good luck.

Objet : [ECOS] New to eCos, struggling with RedBoot
Hello,
I´ve just started learning eCos and am using the book "Embedded Software
Development with eCos" by Anthony J. Massa. I´m trying to set up a
RedBoot floppy on an i386 PC target.
I´m working on a laptop that does not have a floppy drive, and am trying
to use a floppy drive that resides on a network share. The laptop has a
dual boot system with XP and Linux. I´ve been able to mount the drive
using Cygwin under XP, and also under Linux. However, when I run the
command to install to the floppy, it doesn´t work. Below are the steps I
have taken, copied from the Cygwin window.
I may be missing something obvious, but I don´t know. If anyone has
advice, I´d definitely appreciate it!
TIA,
Mike Trozzo
