hi,
can u tell how to configure and build for redboot in ecos configuration
tools..
The steps which i followed is 
From Configuration tool i selected the redboot template for i386pc target..
when i gave build library it reported the following error..
do i have to some more package to it..

I suspect you are confusing the stubs configuration and the
application configuration.

When developing for a typical evaluation board, you will need some
kind of ROM monitor running on that board. This can be an existing ROM
monitor which will not know about things like debugging eCos threads,
or it can be RedBoot or gdb stubs or something along those lines. For
the latter you need to configure and build eCos, generating something
that can be blown into EPROM (or whatever is appropriate for your
target hardware). For the PC target you end up with a boot floppy, but
the basic concept is the same.

Then you need a separate eCos configuration for doing actual
application development. This will differ from the stubs configuration
in various ways, for example the application code will typically be
loaded into RAM rather than blown into EPROMs. Application code built
using this configuration can then be loaded into the target hardware
via the ROM monitor.

So what I think you need to do is create another eCos configuration
using e.g. "ecosconfig new pc default", build it, link the "hello
world" application with the resulting libtarget.a, and then things
should work better.

Hi Niky

Have you ever tried to download any test, which comes with eCos. Try

make tests

in your ecos build directory to compile the tests. After this, download one 
of the test applications located in the install/tests/ directory. If this 
works, maybe your makefile for building your hello application is not ok.

[ECOS] I cant use gdb stubs to load hello

[niky]

Hi,

    I make stubs for pc

    ecosconfig new pc stubs
    ecosconfig tree
    make

    I can execute the version 1.3 prebuild text thread_gdb.exe

    i386-elf-gdb -nw thread_gdb.exe
    (gdb)set remotebaud 38400
    (gdb)target remote /dev/ttyS0
    (gdb)load
    (gdb)continue

    I see

    PASS:<GDB Thread test OK>
    EXIT:<done>

    but I try to execute hello (I make from the version 1.3 example,
    XCC=i386-elf-gcc)

    i386-elf-gdb -nw hello
    (gdb)set remotebaud 38400
    (gdb)target remote /dev/ttyS0
    (gdb)load

    then the pc reboot and does not complete the load.
    What is wrong?
