Other Parts Discussed in Thread: CC2650

I am unable to generate .elf file for ping-ipv6 example for cc2650. I partially found solution here: yet I am unable to impliment it. I am open for suggestions.

thanks in advance.

    Try to use "make TARGET=srf06-cc26xx BOARD=srf06/cc26xx" to make the project.

    Hi Yikai Chen

    I tried with make TARGET=srf06-cc26xx BOARD=srf06/cc26xx. I'm getting same issue

    Hi Vik,

    Did you compile under a clean instant contiki?

    Or from a cloned source?

  • 0 in reply to vik

    Do you modify any source code? I see the link issues are caused by file operation such as _write, _close, etc.

    Hi Igor,
    I followed the instruction to setup contiki in my machine from here: processors.wiki.ti.com/.../Contiki_setting_up_sw
    yes I cloned recursive

    No I didnt modify any code. Infact I recloned the contiki and tried fresh.

    How exactly did you clone the source; git clone, or git clone --recursive?
    Another thing, the wiki says to use "gcc-arm-none-eabi-4_9-2014q4". You have a newer revision, try to downgrade.

    One more thing, why you need the .elf extension?

    I tried with git clone --recursive.

    I now tried wit gcc-arm-none-eabi-4_9-2014q4 toolchain but no luck

    .elf isnt very necessary. .bin .hex will also do... I need cc2650 contiki node to ping to a IPV6 local link address.

    Just try it and see the same problem on my Contiki build environment. Need to dig further to know how to fix it.
