[oe] [Question] How can I use gebserver on oe?

[Journeyer J. Joh]

Hi list,

I am trying to use gdbserver on oe with gdb-multiarch on ubuntu PC.

When I try to invoke gdbserver as shown below :
/ # gdbserver /dev/ttyS0 /usr/bin/my_app

I get error message shown below :
Process /usr/bin/my_app created; pid = 1046
Could not open remote device: Invalid argument.
Killing process(es): 1046

How can invoke gdbserver correctly?
There is no file /dev/ttyS0 so I tried with /dev/ttys0 It is shown below:
(There exists /dev/ttys0)

/ # gdbserver /dev/ttys0 /usr/bin/my_app

Process /usr/bin/my_app created; pid = 1060
Could not open remote device: Input/output error.
Killing process(es): 1060

One thing I am not sure is /dev/ttys0
I need to use serial but I don't know what device name should I use.

Can any one shine some light on my problem?

Thank you very much.
