- Subject: Problem with COM1 port from with GDB 5.3 under Cygwin 1.5.3-1
I upgraded my Cygwin installation two days ago (Thursday, September 4)
to the new 1.5.3-1 version, from the previous 1.3.?-? version.
This broke a self-compiled (under the previous 1.3.?-? version of
Cygwin) version of GDB compiled for "arm-elf" that I use.
It seems to me that GDB simply fails to communicate with the COM1 serial
when trying to make an "RDI" (Angel Debug) connection.
I have recompiled my GNU tools with the with the new version of Cygwin,
but I have the same problem.
I do not have any Cygwin programs handy that I can use to try to use the
COM1 port in some other way. If someone can suggest a simple test, I
will try it.
Can other people use the COM1 port OK with the new Cygwin?
Unfortunately, I did not back up my Cygwin folder before doing the
upgrade - too trusting I guess.
Is there an archive somewhere with all of the old stuff that can be used
to resinstall the old version?
Fortunately, I still have some of the old modules, though - enough to
run GDB under the old Cygwin. From this I know that the problem is not
with the target board or the serial port on my PC.
