[ECOS] PC target -- How to build the GDB stub Floppy ?
Sun Apr 2 23:44:00 GMT 2000
It's a Cygwin problem, I had a similar experience using an Arn board. Here
is the response I got from the cygwin list:

Serial I/O in b20 is broken.

There is apparently a problem with an interaction between the arm-Angel
and cygwin. It is strange in that no other targets are reported to be
affected. This is true of recent snapshots, also.
Sorry. I would like to have someone debug and fix this problem but the
current state is that there is no fix. Well... actually someone here
did create a DLL that seemed to work around the problem but I don't
that it actually solved anything. They just compiled the cygwin
file with -g rather than with "-O2 -g".

Great, that sounds right.

Hmm, this sounds like an NT problem. Not my area of expertise,
unfortunately. Hopefully someone more expert will be able to help
