[ECOS] how to create floppy image for ecos ?

[sivaraman venugopal]

hi
I have build the RedBoot image for an i386 PC
(Redboot.bin file). 
 
it works when i reboot my system.

i also build the ecos library for an i386 PC
(default).

i compiled and linked  the ecos example file
"hello.c", as said in the "Embedded software
development with eCos " book. It produced two files
"hello.o" and "hello" .

how can i create a floppy image of the example
"hello", to boot it from floppy directly.

regards
sivaraman

Take a look at the following page about how to build a floppy-booted
application:

http://ecos.sourceware.org/docs-latest/user-guide/setup-i386-pc.html

It explains everything there.

One thing that I've written which is at times helpful is a little
application in Tcl in order to verify that your floppy image has
indeed been trasferred correctly to the disk.  It's kind of slow,
because it both reads and writes the image, but with the quantity of
bad disks out there, it can save you from scratching your head when
something  doesn't quite work.

It's available here:

http://dedasys.com/freesoftware/

Look under 'scivoli':

wget http://www.dedasys.com/freesoftware/files/md5check.tcl.gz
gunzip md5check.tcl.gz
./md5check.tcl image.bin /dev/fd0

You have to have the right permissions, of course.

I have ported eCos to the iPAQ H3950 (PXA 250). If you are in a rush, the
uE250 tree is a good starting point. .

Sounds interesting!  Are you planning on contributing this
work back to the project?  

Note: that *is* the point of such an open project.  We all benefit
from what has been published and it makes sense to return the favor.

Yet another way to do this:

  cmp image.bin /dev/fd0

or

  diff image.bin /dev/fd0
