hi
In eCos documentation for TARGET SET UP it says that eCos provides two
prebuilt ROM images for EP7211 : one is gdb stubs and other is Cygmon ROM
image . The prebuilt images they have provided under "loaders" directory . I
want to know under what circumstances other image ( Cygmon) is used ?
What has to be done for the option CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS in
ecos.ecc . Right now it is 0 in my configuration . What value should i keep
it when using Jeeni ?
regards
danish.

When you want a command line environment on the target. But if you
don't have the image, it's not an option. Also, it doesn't add
anything in way of debugging.

It's not going to make a difference - you are using a hardware gizzmo
for debugging. Whatever you do to the eCos config is not going to make
a difference.

I have problem to run by step when I use Jeeni too. I was debugging
the gdb-stub image "gdb_module.img".
In my case the following message comes out and gdb session terminated
when I type "stepi":
0 [main] arm-elf-gdb 1003 handle_exceptions: Exception: \
STATUS_ACCESS_VIOLATION
21532 [main] arm-elf-gdb 1003 stackdump: Dumping stack trace to
arm-elf-gdb.exe.stack.dump
Segmentation fault (core dump)
Anyone knows how to fix it or has the same problem?

Have you loaded the symbol information from the ELF file into
gdb?
What exactly happens when you do a "step" command?

The GDB mailing list is indeed the correct venue...

Then it's a problem with GDB's Jeeni support. It has nothing to do
with eCos per se. I suggest you ask on the GDB mailing list.

RedBoot you mean - it's the CygMon replacement. And it does not
provide any debugging features not already provided by the stubs
(well, it allows debugging over ethernet, but that aside).

ya ! i am including the debugging information ( -g option) and able to see
the source code on the gdb terminal .
Is there any other option which may be hinderinig the working .
Right now , i am having the gdb stub in the EP7211 board which initialises
the board & after that i conneect through Jeeni .
Do i need to enable some option in ecos.ecc to work in this combination (
using Jeeni) . If i run the same code using serial port ( without Jeeni)
everything works fine .
I would like to know what is Cygmon and can i download that to the target
in place of gdb stub and work . How is that supposed to work ?
Does that need to change any options in ecos configuration ?
regards
danish.

Did you include debugging information (-g option)? Without it there
would be no line information to allow a regular step instruction to
work.

Hi
I am using EP7211 board and Jeeni to connect and run my application
through it using GDB. For that i wrote a simple C program , then connected
to the target board via Jeeni and downloaded my application .
But when i run( continue) , it is not coming even upto main() .
It initialises the h/w and then enters the eCos Scheduler region and there
it is looping sort of between scheduler fn and some thread implementation fn
.
I can't undersatnd what's wrong with it .
moreover i am not able to do step even through GDB ..i have to use "stepi"
in place of that ...why it is so ?
regards
danish.

Using JEENI means you don't need GDB stubs (disable "Include GDB
stubs in HAL). Your arm-elf-gdb is talking to the ICE via direct serial
connection or ethernet connection (select ANGEL/serial or ANGEL/Ethernet
in Taget Setting if you are using insight-5.0 for arm-elf)
Some hints can be found in the FAQs of JEENI
( http://www.epitools.com/support/arm/faq_jeeni.shtml )
However, it is talking about gdb-4.18.
For diagnostic output, you should "disable GDB protocol for diagnostic output"
and using HyperTerminal or minicom to connect to the UART of your board.

Hi
i have build ecos on the linux host for EP7211 target board .
i want to connect to the target board through the Embedded Ice (Jeeni).
Does it also requires that gdb stub should be sitting inside the board . In
ecos.ecc file there is option for serial port for the diagnostic output .
But if we use Jeeni what happens to tha diagnostic output . where will this
output be printed and how .
do i need to configure some options in ecos.ecc to be able to make it behave
decently with Jeeni .
thanks
danish.
