Insight and com port problem

Hi,
I recently built Insight from the the snapshot (I 
am not sure if it's a release) insight-1999122.tar.bz2 for the ARM processor on 
a WIndows NT platform.
So far so good, the simulators works fine. I 
encounter problems while connecting Insight serially to the ARM Evaluation Board 
(Target ARM Angel). Sometimes a connection is made and a few single steps can be 
executed. It seems the com port hangs after receiving the copyright message from 
the AEB. Actually the program Insight sends a response packet but the 
transmission stops somewhere in the middle of the packet.
Obviously the AEB awaits the reception of the 
complete packet and will therefore wait forever.
 
I have checked some mail from the archive and read 
that some people where lucky by replacing cygwin1.dll by the latest version 
cygwin1-20.1.dll.  I am afraid luck is not on my side this time 
because it is still not working with this update. Has anyone 
experience and give me some hints / clues ?
 
Thanks,
Marcel 
Wust.

Marcel, it works perfectly around here.  My AEB board is rev.c (I never
tested with a rev.b board).

Can you please give it a try without the GUI?  Just call gdb with the
-nw option.

target rdi com1
load
b main
cont

should work fine.

If not, please get the atest gdb snapshot as people from the net have
been contributing some improvements that I have added to the code
recently.  I myself have made some improvements to the serial connection
code.

W.r.t. the cygwin1.dll, yes, it is true you need a newer version.  I
will investigate which one is better and get back to you tommorrow.

Please let me know what you see without the GUI.  My e-mail is below.

Thanks,
Fernando
