Hello everybody!

I try the new stm32cube examples, with CoIDE. I check the truestudio example, and make the CoIDE project same for this, but I have linker error and I dont know what is the problem. This is the stm32f4-discovery demonstration project.

    You can try to use the files generated for the Atollic toolchain as this toolchain uses the same

    kind of compiler.

    I use the attolic files. I try and the problem with startup file. I dont use startup file before, I use systeminit function at the begining of main. What is the difference of startup file use or call systeminit at the main function?

    for _sbrk() look to syscalls.c used for newlib support ?

    for __libc_init_array consider if you're using C++ constructors, and if you can remove the call from startup_stm32f4xx.s ?

    I don't see syscalls.c at the project files. Maybe the atollic add this file for the project?

    Ohh so I need to modife the startup file or install g++ compiler?

    It's in several dozen of the projects:

    STM32Cube_FW_F4_V1.1.0\Projects\STM324x9I_EVAL\Applications\Audio\Audio_playback_and_record\TrueSTUDIO\syscalls.c

    I've built similar support files for GNU/GCC projects where I want to support printf(), scanf(), putchar(), etc in

    , though I've modelled things more closely with RiDE rather than Atollic

    Thats ok, I have syscalls.c but in demonstration project not included. I don't no how the truestudio compile the project without this.
