oh I just forgot to show us the output using the file command in GDB: (gdb) file obj/web.o Reading symbols from /../build/obj/web.o...done. (gdb) break web_init Breakpoint 1 at 0x3490: file ../../.../web.c, line 231. (gdb) run Starting program: /.../build/obj/web.o Don't know how to run. Try "help target". (gdb)
I also get this message, if I don`t use any breakpoint conditions. So maybe the file command is correct to set breakpoints but I need some additional information to get the target running -------- Original-Nachricht -------- > Datum: Tue, 18 Dec 2012 09:39:18 +0100 > Von: "Bernd Schuster" <schuster_be...@gmx.net> > An: "Bernd Schuster" <schuster_be...@gmx.net> > CC: ecos-discuss@ecos.sourceware.org > Betreff: Re: [ECOS] Re: GDB stub support > Hi, > > ok I got the first step working.
