Undefined reference to snprintf in Cortex R5 using arm none-eabi compiler

Likely due to linker script problem. Most of linker usage problem can be resolved by following the sample projects delivered with toolchain. To do so you can go to share/gcc-arm-none-eabi/samples, and follow the command line and linker script in projects there. Hopeful it helpful.

Hi Joey,

Thanks for the update. I re-checked and it uses the following sequences in linker file which collides in order vs unordered linking. Also this happens specifically when I am trying to access functions like snprintf() and vsnprintf().

        .ARM.extab :
        {
                *(.ARM.extab* .gnu.linkonce.armextab.*)
        } > FLASH

        __exidx_start = .;
        .ARM.exidx :
        {
                *(.ARM.exidx* .gnu.linkonce.armexidx.*)
        } > FLASH
        __exidx_end = .;

your answer is unclear
