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

looks like an attempt at putting spam links in a post ?

your answer is unclear

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 = .;

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 Andy,

Removing -nostdlib has no effect. But removing -nodefaultlibs lead to link error as follows,

.text has both ordered [`.ARM.extab' in libgcc.a(_divdi3.o)] and unordered [`.ARM.exidx' in libgcc.a(_divdi3.o)] sections
