RE: [ECOS] New to eCos, struggling with RedBoot

["Michael Trozzo" <trozzo at arcor dot de>]

Hello Denis,

I've also tried to do this under SuSE Linux. In Linux, I mounted the
floppy that's on the other box as follows: 
mount -t smbfs //192.168.0.1/a /dev/floppy 
and I can see the drive and its contents. I attempted to mount it to
/dev/fd/0, but it wouldn't let me because it's not a directory.

When I run the dd command, it just says that /dev/floppy (which is a
folder I made) is a directory. I've also set of=/dev/floppy/redboot.img,
and get the success message (174+1 records in, 175+1 records out), but
when I put the floppy into the target machine, it wouldn't boot, giving
me a non-system disk error). 

I've rechecked my settings in eCos, and believe that they're right
(importing redboot_FLOPPY.ecm, etc.). I'm at a loss for ideas..is there
any possibility that the problem is that the floppy drive isn't local to
this machine, but a network share? Since I'm also not getting it working
under Linux, I doubt that the cause is strictly Cygwin.

Thanks,
Mike

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
