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 nc_test_slave/master test 
programs.

But I cannot run h8300-elf-insight,so please help me.

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

After insight is started up,I entered next commands on console window.
----
(gdb) set remotebau 57600      --- I setted baudrate 57600
(gdb) target remote /dev/com4
Remote debugging using /dev/com4
0x000073a4 in ?? ()

(gdb) load
Loading section .text, size 0x599ce lma 0x410000
Loading section .rodata, size 0x406a lma 0x4699ce
Loading section .data, size 0x1660 lma 0x46da38
Start address 0x410000, load size 389272
Transfer rate: 3 KB/sec, 63 bytes/write.

(gdb) b cyg_start
Note: breakpoint 2 also set at pc 0x411dca.
Breakpoint 3 at 0x411dca: file nc_test_slave.c, line 729.

(gdb) c
Continuing. ...

At this point nothing happens.Although state is "Running" and mouse_cursor 
is running 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.

(gdb)

My guessing is GDB stub not functioning properly.

Here are questions.
First of all,couldn't I set "net"and "stubs" Packages together on ConfigTool 
?
By Packages,I mean,it is in Templates dialog-window not in Packages 
dialog-window.
When I selected "net",there's nothing in  Packages dialog-window 
corresponding to "stubs" function.
If I could not set both functions together on ConfigTool conveniently,then I 
must convert cdl files.

I think next Options are related to GDB stubs.
CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS
CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT
CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT
CYGDBG_HAL_DEBUG_GDB_THREAD_SUPPORT
CYGBLD_BUILD_GDB_STUBS
CYGBLD_BUILD_COMMON_GDB_STUBS

I checked current definitions in cdl files.
cdl_option CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS {
    default_value 0

cdl_option CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT {
    requires      CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS
    default_value CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS

cdl_option CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT {
    active_if     { CYGSEM_HAL_USE_ROM_MONITOR || 
CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS }
    active_if     { CYGINT_HAL_DEBUG_GDB_CTRLC_UNSUPPORTED == 0 }
    default_value { !CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS }

cdl_option CYGDBG_HAL_DEBUG_GDB_THREAD_SUPPORT {
    active_if     { CYGSEM_HAL_ROM_MONITOR || 
CYGDBG_KERNEL_DEBUG_GDB_THREAD_SUPPORT }
    default_value 1

cdl_option CYGBLD_BUILD_GDB_STUBS {
    default_value 0

cdl_option CYGBLD_BUILD_COMMON_GDB_STUBS {
    default_value 0

How should I set these options in order to insatall GDB stub ?

I am very much obliged to your help.
