===================================================================
> hello
sorry for re-asking you but there is something
missing.

1- I want to connect eCos to RedBoot via serial.
   When I'm trying to use the GDB as you said in   
point(2) the is done but When I'm trying to run it
using (continue), the redboot is halted and then I
could do nothing than restart it.

In addition, I found that I have a problem that I must
enable (CYGPKG_IO_SERIAL_DEVICES).
When trying to enable it using
     ecosconfig add CYGPKG_IO_SERIAL_DEVICES
told me that it is'nt package

when trying to enable it inside the ecos.ecc. when
running 
     ecosconfig tree
it returns disabled.
I don't know how to enable it. Have you has a
suggession? tell me?

           
 2- I want to try build the program image on floppy
using commands you tell me before. I'm booting RedBoot
from floppy to RAM and then released the RedBoot
floppy and put the floppy that have the program image 
(basic.bin) file. Then, I'm trying to load it using

redboot> load -m disk redboot.bin
or
redboot> load
or else
but I coudn't.
Please tell me is my way true and what is the wrong in
it? And What is the solution?
     
                        Thanks very much
                        Muna

As has been said before, try running some of the standard tests and
check that they work before running your own programs. Nobody else has
these problems so it is either in your program or in the hardware of
your target. Why don't you try building and running the tm_basic
kernel test program and post the output from the GDB session here.

I don't know where you got this package name from, the correct name is
CYGPKG_IO_SERIAL.

That will not work, there is currently no support in RedBoot for
loading files from floppy. They must either be downloaded via the
serial line or fetched from a TFTP server.

hello

 1-The(CYGPKG_IO_SERIAL_DEVICES)is defined in ecos.ecc
to enable the device drivers. I found that I must
enable this component in on of the ecos-discuss
mailing list.
the CYGPKG_IO_SERIAL is enabled but that component is
disabled.

2-how can I fetch any test program from a TFTP server

                              thanks
                             muna

It is not a package, you have to enable it yourself, either by editing
ecos.ecc, using the graphical configtool, or by using an import file.

This is explained in the RedBoot documentation.
