[ECOS] Help with gdb stub problems

[Christian Sommerfeld <csommerfeld at bihl-wiedemann dot de>]

Hi at all,

i am a newbie and i have a lot of questions about the GDB without ROM
monitor. I hope somebody can help me.

I set up the GDB without ROM monitor. It seems that it works fine, with
a simple program. i am using:
########################################################################
GNU gdb (CodeSourcery Sourcery G++ Lite 2007q3-53) 6.6.50.20070821-cvs

Question 1+++++++++++
I guess i have to set "breackpoint();" in my program to stop. I cant set 
the breakpoint from the GDB (host=pc), right? If i set it and the 
program reaches the breakpoint it stops always in the hal_misc.c file. 
Is there a possibility that it stops in my c-file? s (step) isnÂt 
working at all. same failure like in question 3.

Question 2+++++++++++
If i write more than one breakpoint in my file, the program stops an
every one, but after it reaches the second i get always
"Program received signal SIGTRAP, Trace/breakpoint trap."
Whats that? and how i can solve this problem?

Question 3+++++++++++
I tried to write

HAL_BREAKPOINT(_breakinst);

in my c-file. (normaly it is in the hal_misc.c) the program stops now in 
my file. I can set/print variables and jump to line numbers. All that 
works fine. But if i want to step throut the code lines with s (step) it 
jumps always on the end of the current function. If i use s again the 
GDB(host) jump in the next line and nothing happens anymore. Why? Any idea?

Question 4+++++++++++
I have 6.5.50.20060517 version of Insight. If i tried to set it up with:
target = remote serial and the right baudrate and port, it always hang
up if i start insight with run. Is there a verion of Insight (exe) which 
is working?


If you need some more infromation, please let me know!


Thanks a lot for your help!
Christian
