Re: [arm-gnu] Sprintf on Cortex M1 (G++, working standard functions)

["Hondorf, Tobias" <Tobias.Hondorf@xxxxxxxx>]

Thanks for the response.
It seems it is because of the linker script i use. I dont use a CodeSourcery specific one. (The one i use was provided with my Board, and I adepted it for my use...) When i link my object files without adding the linkerscript parameter it seems to work. But i wonder which linkerscript is used when i dont use the "-T script.ld". According to the documentation (Getting Started Guide, page 58, paragraph 6.5.3) i need to set the -T parameter, it says nothing about any default script when not using it.

Maybe someone got an idea. Sorry bout those silly questions. Im sure it is pretty common knowledge but google and this mailing list dont have answers for me.

It sounds like you didn't supply a correct linker script.  See the supplied linker scripts or the section on CS3 in the Getting Started Guide for more information.
