In my case, I only have the redboot run on the target board. As I mention
above, I can't find other templates (e.g. kernel) can generate .bin/.elf in
the bin directory except redboot, cygmon and stub templates can generate
.bin/.elf files.
If I want to build the ecos (kernel) and the load it to the target board,
and run it via redboot command (go), how can I do?

Thanks! :D

Tests *won't* appear in the bin directory, they will appear in the tests
directory. Please read what I wrote more carefully.

All you need to do is download those test executables then - using GDB is
the easiest and most appropriate (although you don't strictly have to - it
would just be easier).

There's no image to go in the bin directory. You link eCos directly with
your application. Have a look at the examples, as mentioned in the eCos
Getting Started manual.

I am sorry that I haven't state clearly what I have to ask.

I already know that the tests will appear in the tests directory when I
select other templates (not redboot) and then click build tests.

My target board only have redboot on it. If I want to build up the eCos so
that it can run on the target board, how should I do?

I use the kernel template to bulld up  the ecos but the config. tool cannot
generate the image file in bin directory. Why?

Should I  wirte a makefile in order to generate the image file?

Thank you very much , you are helping me a lot.

The best thing is to use GDB on the ELF executables.

No, when GDB connects, RedBoot will switch mode automatically.

If you just use the default template, then if you choose build->tests from
the graphical configuration tool, or type "make tests" if you are using the
command line, then you will also get a "tests" subdirectory underneath
untitled_install.
