RE: multi-ice-gdb-server - ReadChar Problem..

Hi all,
I found the workaround for this problem.
I want to share this with all of those who encountered this problem.

Just comment the below code in remote-utils.c

#if defined(F_SETFL) && defined (FASYNC)
  save_fcntl_flags = fcntl (remote_desc, F_GETFL, 0);
  save_fcntl_flags |= FASYNC;
#if defined(O_ASYNC)
  save_fcntl_flags |= O_ASYNC;
#endif
  fcntl (remote_desc, F_SETFL, save_fcntl_flags);
  ioctl (remote_desc, FIOASYNC, &enable_async);
  disable_async_io ();
#endif /* FASYNC *

It works.. ....

Happy debugging ....

Hi All,
Recently I have downloaded multi-ice-gdb-server and managed to compile and
run according to the instructions in
http://ecos.sourceware.org/multi-ice.html after running the below command I
get the errors as shown.
The multi-ice-gdb-server is failing at readchar function.

##"C:\Program Files\ARM\Multi-ICE\multi-ice-gdb-server.exe"
--remote-port 9000 --byte-sex l --config-dialog

GNU Multi-ICE GDB server 1.0


Connected to the Multi-Ice target.

Targeted ARM core: ARM9 0

Target characteristics:
        Hardware?:              YES
        Comms Channel?:         YES
        Endian-ness:            LITTLE
        Single-Step Support:    NO
        Load Size:              32768
        Custom Load?:           NO

No other modules found on debug target.

GDB Server starting on port 9000

Got a connection from localhost

Not a good vector or eCos not running!

putpkt(read): Resource temporarily unavailable

readchar: Resource temporarily unavailable



I Think many people have faced the similar problem. I searched mailing list,
could not get any solution to this.
Does this problem have any workarounds or solutions or suggestions  or some
specific version of CYGWIN to be installed.....
Pl let me know..

I am also working on this ....

Hi --- since this isn't a problem in GDB or gdbserver, are you sure it
wouldn't be more appropriate to report this problem as described here?
