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). xxx@linux-xxxx:~/.../build> mipsisa32-elf-gdb GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

(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 -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
