Re: [ECOS] Re: GDB stub support

["Bernd Schuster" <schuster_bernd@gmx.net>]

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
