Re: Re: GDB stub support


Hi, 

ok I got the first step working. I`m able to download the .elf file by the serial connection to my target. 

But could you tell me how I could set some breakpoints at function "web_init" or at line 233 (file web.c).

(gdb) break obj/web.o
Can't find member of namespace, class, struct, or union named "obj/web.o"
Hint: try 'obj/web.o<TAB> or 'obj/web.o<ESC-?>
(Note leading single quote.)
(gdb) 

I also tried: 
(gdb) break web_init
No symbol table is loaded.  Use the "file" command.

Using the file command didn`t solve the problem, because it seems to me that GDB didn`t recognize "myprogramm.elf" any more - only the specific file. 

best regards
Bernd
