[ECOS] Help: arm-elf-gdb com1 error

[Seran]

Hello,
     I am using Atmel EB40A evaluation board (AT91R40008 processor ARM7 core
based) to test my projects. I was trying to connect to the target board
using the arm-elf-gdb.exe, but when I specified the serial port connection
as target I got the follosing error:

GDB
   com1: No such file or directory

   GDB cannot connect to the target board using com1.
   Varify that the board is securely connected and, if necessary,
   modify the port setting with the debugger preferences.

I dont know the reason for this error. I tried to change the target's but
was not successful.  Can any one help me to solve this problem.


Thanks
Seran

  Try using /dev/ttyS0.

  Regards.

Does Cygwin map /dev/ttyS0 to COM1?  I always used COM1 as the
device name under Cygwin.

I think cygwin now requires /dev/com1

  Yes.

  Using the ttySX names allows you to use the same unmodified scripts for 
Cygwin and UNIX, though.
