Hello
I am trying to use gdb to download using cygwin
When I enter the command /opt/ecos/gnutools/arm-eabi/bin/arm-eabi-gdb.exe
DevBoard_install/tests/io/serial/v3_0/tests/serial3 I get returned to the
command prompt straight away
Why is this?
Graham

Make sure that all the Cygwin packages required for eCos are installed. Ref:

Yes, but there are several other Cygwin packages that you also need to
add, as described at:
http://ecos.sourceware.org/cygwin.html
Cygwin-hosted GNU tools have been known to fail silently when required
DLLs are not installed.

arm-eabi-gdb.exe requires the following Cygwin DLLs:
C:\cygwin\bin\cygwin1.dll
C:\cygwin\bin\cygexpat-1.dll
C:\cygwin\bin\cygiconv-2.dll
C:\cygwin\bin\cygintl-8.dll
C:\cygwin\bin\cygncurses-8.dll
C:\cygwin\bin\cygz.dll
So if any of these DLLs don't exist in your own Cygwin installation,
that could explain the problem you are observing. If you have installed
all the packages listed on the above page and still don't have all the
DLLs you need, please let me know which one(s) are missing in your
installation.

I expect this is the problem. Try adding the Cygwin "libexpat1" package
to your installation by re-running the Cygwin setup program (make no
other changes).
Please do let me know if this resolves the issue so I can modify the
installation instructions if necessary.

Thank you for the confirmation (and independent confirmation from
Bessemer). I have updated the Cygwin installation page on the eCos website.

Good.

Recent Cygwin uses Linux-like serial device naming. Try:
(gdb) target remote /dev/ttyS3
