Hi!

This patch note should be good. (If you make a patch file just like those
on the http://ecos.sourceware.org/build-toolchain.html.)

I was able to make a GDB with the patch and it is working well.
I can connect with it to both angel and redboot.

I bulit a project from EB40 template with tests in the configtool.
But as cygwin changed i could not run test on the target.
As i see the configtool configures GDB to connect to the target on COM1.
(Which as we know not a serial port on cygwin 1.5.*.)

Now if i run GDB and connect to the target with the

 target remote /dev/com1

command.Everything works well.I can load for example the "bin_sem0" test
elf file and i can run it with success.

Maybe there is more change (com?->/dev/com?) to do in the work but as a
starter i can see just this one.

Please rebuild the pre build gdb with the patch! As a starter the pre
build tools were my only chance to start playing with GNU/eCos!
For a starter the tool build process is a nightmare.
I think i will be unable to make an insight for myself.:(

I have other experiencese but i dont know if i would tell you them, or
write them to the list.

Thank you for reading my email
