[ECOS] can u tell me why is it not booting ?

[Samiran]

Hello Mr,

I didn't get ur point, "A good start would be getting eCos from CVS."

 can u tell me why my pc is not booting from floppy
I did 
 eCos Configuration Tool
1) File->new
2) Build->Templates	hardware-> i386 PC target
				Packages ->stubs
3)then save 
4)build
it is successful 
then I did 

dd conv=sync if=insatll/bin/gdb_module.bin of=/dev/fd0
when a: is mounted like this \\.\a: on /dev/fd0 type user (binmode)
at that time it is showing 
44+1 records in
45+0 records out

then I tried to boot another pc to boot, from that floppy

but it is not booting

when I am going to connect through gdb it is giving 

(gdb) set remotebaud 38400
(gdb) target remote /dev/ttyS0
/dev/ttyS0: No such file or directory.
(gdb) target remote /dev/ttyS1
Remote debugging using /dev/ttyS1
Ignoring packet error, continuing...
Ignoring packet error, continuing...
Ignoring packet error, continuing...
Couldn't establish connection to remote target
Malformed response to offset query, timeout

thanks 

samiran

A good start would be getting eCos from CVS.

Get the latest version of eCos from CVS. You are using 1.3.1 which is
very old.

[ECOS] on gdb and exception handlers..

[gopi]

hi..

  I am currently using cygmon(and plan to move to redboot once the
platform support is available) on IXP1200EB with IXP1200 n/w
processor.  I took the cygmon code from netwinder.com provided by
the intel guys.

  In the source code, they said they had some problems with
using gdb.  Hence I am not able to use the singlestep etc features
on cygmon.  Before fixing the problem,  I wanted to know the
following things(on using gdb over a serial line)

  + Which part of the boot loader(or cygmon) can I single step
    using gdb?
  + is gdb used to debug cygmon or applications running over cygmon?

Another question regarding exception handlers:
  In our case, cygmon is started by some other code sitting in
  flash(@0x0).  The exception handlers put by the other code is
  not accessible to cygmon.   But cygmon is still able to receive
  interrupts(uart code is working with interrupts enabled).
  Even the MMU is disabled.

  So, when an uart interrupt comes and an exception is raised,
  who is calling the exception handlers of cygmon?

  What is the link between the actual exception vectors(@0x0, 0x8,
  0x12 ..) and the cygmon exception handlers?

thanx in advance
gopi
