Including .s file in building process [arm-none-eabi-toolchain]

Hi guys,

I'm try to include a set of ASM functions in a project. I have to build this project with arm-none-eabi on a STM32F4-Discovery. My question is how modify the makefile to include the correct building process?

I tryed to add SRCS += filename.s line but it does not like

to the compiler

that reply: No rule to generate object ''path/filename.s''. needed for ''main.elf''. Stop.

It's sound strange because in the make file there is yet a .s ''startup_stm32f4xx.s'' that seems included with the synthax above.

I attach it for your considerations.

Regards

What is the actual name, ''filename.s'' or ''path/filename.s''

Make sure the name specified in Makefile is exactly the same as the file you try to compile.

Pay attention to new file location. Try to put this file in same location as other .s files & use same syntax.

Your OBJS definition creates a .o dependency list from the .c files it sees in the list using a substitution, it does not address .s or .S files. You will likely need to have a couple of lists and combine them.

I've done some GNU/MAKE stuff here using a template that I found that worked well for me

Makefiles are complex, people have written whole books on using Make, suggest you review documentation, and search web for examples that suit your needs.

Ok file paths match ! and the build process was gone... with errors #%$! I'm more confused now.

Are you using STDIO printf/putchar or malloc/free type functions? NEWLIB? You seem to be missing code to implement SYSCALLS on your platform.

Great Clive1,

I tryed on the fly your suggest (stdio lib was included) and ...yes I built it!...

Tonight I check the code for ensure that all work properly.

Thanks again,

Regards

Another thing,

I'm assuming that the asm function is located on .s file, that the functions put return values in r0 & r1 (UAL rules) and that this functions are called by the main.c file. The problem is that when I try to execute this:

.section .text.Default_CPUTest_Handler,''ax''

.weak Default_CPUTest_Handler

.type Default_CPUTest_Handler, %function

Default_CPUTest_Handler:

CPU_RegisterTest:

mov pc,lr

push {lr}

mov r0, CPU_REGISTER_TEST_PASS

push {r0}

pop {r0}

pop {pc}

.end CPU_RegisterTest

.size Default_CPUTest_Handler, .-Default_CPUTest_Handler

called by:

1.
int testRes=CPU_RegisterTest();

in the main.c, trying to change r0 TestPassCondition from FAIL to PASS (from 0 to 1), the result is the same testRes ever maintains the 0 value. Anyone can explain how to return from ASM func correctly? thanks Regards
