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.
-- GDB commands on console window log

.
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.
# user_value 0
# value_source default

# --> 1
};

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.
