    I know this is an old post. I'm trying to build this SDRAM example code with gcc arm embedded toolchain. The none-eabi linker is give me an error that .ARM.exidx overlaps .DATA section. I can't find .ARM.exidx section in stm32f429i.ld?

    It build some .bin and .hex but no .elf

    I still did not try to run the binaries. I hope someone can still reply on this post.

    And you're doing this with what version of the GNU/GCC tools, on what platform?

    I provided a MAKEFILE which works fine with GNU/GCC 4.7.2 under Yagarto

    I'm cross-compiling on a Win8 machine. I'm building the executable with make under cygwin env.

    The toolchain is gcc-arm-embedded and the compiler version is 4.9.3.

    Suggest you review the linker scripts (.LD) they use, and adapt those to reflect the memory map described in mine.

    I don't know if I'm in the right corner here to ask. If I use libc I get the linker error. Is libc compatible with stm32f429i.ld?

    gcc-arm-embedded includes the red hat newlib libc 2.1.0

    I try to figure out with the libc manual.

    The least resisant path was indeed to use the supplied ld script from gcc-arm-embedded toolchain and morph it to the map of stm32f429i.ld

    In fact libgcc use the .ARM.exidx section.The stdio functionality.

    I conclude the newlib lib in YAGARTO is different build then the gcc-arm-embedded newlib.
