Does not stop at break point in GDB-remote

Hello,

I am working on eCos 3.0 using Akizuki H8/3068 Network board.
That board's CPU is H8/3069F.
I succeeded to install FreeBSD stack and ran TCP/IP test programs.

But I cannot run Insight or GDB,so please help me.
Insight person suggested me to ask GDB mailing list.

I start up Insight like next line.
$ h8300-elf-insight.exe nc_test_slave.elf

I made this nc_test_slave.elf by renaming nc_test_slave file that is 
outputted excuting "make".
Here are excerpts from makefile.
---
export PREFIX := 
/home/link/aki-net-0910-config-stub-global-common/untitled_install
XCC = h8300-elf-gcc
CFLAGS 
= -mh -mint32 -g -Wall -I$(PREFIX)/include -ffunction-sections -fdata-sections
LDFLAGS 
=  -mh -mint32 -nostartfiles -L$(PREFIX)/lib -Wl,--gc-sections -Wl,--Map -Wl,nc_test_slave.map
LIBS = -Ttarget.ld -nostdlib
LD  = $(XCC)
all: nc_test_slave
nc_test_slave.o: nc_test_slave.c
 $(XCC) -c -o $*.o $(CFLAGS) $<
nc_test_slave: nc_test_slave.o
 $(LD) $(LDFLAGS) -o $@ $@.o $(LIBS)

After Insight was started up,I entered next GDB commands on console window.

 .
Here never stops at break point(=cyg_start).
Nothing happens,although state is "Running" and mouse_cursor is sand-glass 
form.
Nothing available(even Ctr-C does not work) except stop button on 
insight-window's main head.
When clicked stop button,appered message window saying,
"No response from target.Detach from target
(and stop debugging it)?"
And clicked YES button, then appeared next line.

Error: Watchdog timeout has expired.  Target detached.

I do not know why it does not stop at break point(=cyg_start).

For reference, I set GDB stubs options like below(sorry it's from eCos ecc 
file).

cdl_option CYGBLD_BUILD_GDB_STUBS {
    # Flavor: bool
    # No user value, uncomment the following line to provide one.

};

I send remote-5.log,and map file that was created by making 
nc_test_slave.elf,both in compressed form.

I'd appreciate any help.
