Hi all,
After a lot of help from Norbert and Mikhail I could put GDB to work with
my development board, using the Zylin plugin
(http://www.zylin.com/embeddedcdt.html).
However, I have to do the same with the SPARC Instruction Simulator (SIS),
as we have just one board and some developers (it's an ERC32 processor, a
very expensive one) to work with it.
When starting a debug session on the real processor everything works fine.
But when trying to do the same with SIS, there's no answer to the last GDB
command, "run".
I can debug the simulator directly from the command line, and even using
the DDD graphical interface to GDB. But not with Eclipse / CDT.
I ran gdb from Eclipse and from the command line (with "interpreter=mi"),
and there's some differences between the sessions.
(A session with Eclipse)
[...]

[1.132.204.641.328] (gdb) [1.132.204.641.344] &"run\n"
(and there's no other message)
(A command-line session)
(gdb)
tar sim
&"tar sim\n"
~"Connected to the simulator.\n"
^done

&"load\n"

(gdb)

&"run\n"
^done,reason="breakpoint-hit",bkptno="1",thread-id="0",
frame={addr="0x02001210",func="Init",args=[{name="ignored ",value="0"}],
file="hello.c",line="13"}
(gdb)
As you can see, from the command line we know that the breakpoint was hit,
but not from Eclipse. What can be happening?
Thanks in advance,
Fabrício.
