Hi! I am searching for some space in Flash, and I the following is realised: .comment 0x00000000 0x1b ../lib/gcc/arm-elf/4.1.1/crtbegin.o .comment 0x00000036 0x1b ../lib/gcc/arm-elf/4.1.1/../../../../arm- ... there are many object files containing the text "GCC: (GNU) 4.1.1 (WinARM)" How can I disable it? (I use gcc option -fno-ident in my sources.) Thanks, Ádám

I have no idea what that means or where you got it from. What about it!? Tell is what or where it is so we might interepret what you are concerned about. > > there are many object files containing the text "GCC: (GNU) 4.1.1 > (WinARM)" > What appears in an object file and what appears in the binary are two different things. Some information is there to help the linker and debugger and are not incorporated into the ROM image. If you want to find out what is where and how much space it takes, generate a link map when you execute the linker.

You have right, I changed the linker script and the .comment section will not appear in the binary. (My first idea was to recompile the libc and the *.o-s with -fno-ident option.)
