Thanks! .

Think you're right, from the GCC documentation it looks like we should have used either .sx or .S. So I have reported this internally. Thanks for lettings us know! Will update this thread as soon as I get some feedback on it.

The issue is still present in the GCC v4.9, I also confirmed it with SDK11 on nRF52. It is definitely related to the file name, as you can see in the GCC documentation: link GCC Options. Please search for '.sx' in this document. Also see the -x option some lines below.

.s files contain assembler code (usually generated from .c files) that do not need the C preprocessor to run over it again. If assembler code contains C preprocessor directives, the file shold be named .sx or .S (upper case). Alternatively, the GCC option '-x assembler-with-cpp' may be used to explicitly instruct GCC to run the C preprocessor on the .s file, but that doesn't comply with standard GCC file naming schemes.

I really think this is a naming issue, and that the current SDK doesn't comply with the common C / Assembly file naming standards.

I haven't heard reports of this issue with v.4.8 before, but I guess it's worth a shot. Another thing to try is to build with a clean copy of a SDK and see it it still does not build 'out of the box'.

Thanks for the hint. When I find some time, I will try it out with version 4.9.

Yes, I'm using Windows. We were using 4.7 2013q1 further in the past but due to some issues, we had to update to 4.8 2013q4.

Are you working on windows or a different platform? See that gcc-arm-embedded 4.7 2013q1 was used for testing of the older SDKs

Hi, I haven't had any problems with using the .s extension. Although it has been awhile since I've used version 4.8. Using 4.9 I'm able to use the __STACK_SIZE,etc defines by adding them to asmflags in the makefile.
