Freertos compilation error on Sd32 studio

[prashantsathe]

I am trying to build a project based on MAC57D54H (for M4 core). For this i have added basic freertos code. after successfully compiling 'c' code i am facing asm file compilation error. Could you please check this.

Portasm.s is attached.. current port is for IAR compiler, I am trying to port it on arm-none-eabi-gcc.

Would be helpful if you could point out the PATH to proceed, I am new to asm (only long back worked on ASM).

Error :-

Thanks,

Hi Prashant,

I'd suggest you to add the assembler directive into portasm.s:

.syntax unified

https://sourceware.org/binutils/docs/as/ARM_002dInstruction_002dSet.html#ARM_002dInstruction_002dSet

enable floating point ABI:  hard

FPU Type: "fpv4-sp-d16"

Hope it helps.

Hi Prashant,

The GNU assembler (known as GAS) directives may differ from the ones located in your assembly file.

I'd suggest to use:

.global  instead of .export

.extern instead of .import

Could you attach your portasm.s if it does not help ?

Thanks.

Stan
