Build startup_cortexA15MPcore using GNU toolchain. URGENT.

Dear all,

I am trying to build the example  startup_cortexA15MPcore (provided with DS-5)  using GNU toolchain. The example is originally designed for build using ARM standard tools, and the following variables are hence defined :

CC=armcc

AS=armasm

LD=armlink

AR=armar

FE=fromelf


With what GNU tools should I substitute CC, AS, LD, AR, FE so that the example can be built using GNU toolchain. Does the below work:



CC = arm-none-eabi-gcc

AS= arm-none-eabi-as


LD= arm-none-eabi-ld



how about AR and FE?


Please help thank you very much.

  • If you're lucky, you could use the C Pre-Processor in GNU as a wrapper around your ARM assembly files.

    Say... You have foo.as and you want to assemble it using GAS; then wrap the C Pre-Processor aournd GAS for files ending in ".S"

    To wrap GAS in the C Pre-Processor, use GCC with the '-x assembler-with-cpp' switch:

        arm-none-eabi-gcc <some parameters> -x assembler-with-cpp <other parameters>

    Make yourself an .S file like the following:

    #define KEYWORD    replacement

    ...

    ...

    #define KEYWORDn    replacement_n

    ... After all your #define macros, you can include your ARM-assembly file:

        .include    "foo.as"

    ... or even ...

    #include "foo.as"

    Of course, it will not handle all cases, so you may experience the need for modifying the .as files, so they will become "portable"

    Also have a look at GAS's macros. They're quite powerful, and may be able to override keywords in your .as file too.

        .macro    macroname,param1,param2

        .ifnb    \param1

        ...

        .else

        .endif

        .endm
