How to generate .axf file for nRF SDK 16.0.0 for a nrf52833 chip?

[addngkr]

I am working on a nRF52833 chip and using nRF SDK 16.0.0 version. I need to analyse the memory footprint of my project for which I would need access to .map and .axf files. Upon searching in my repo, I could locate the .map file in build directory but couldn't find .axf file. Is it possible to generate the .axf file for my project? If yes, then how do I go about it?

I use gcc-arm-none-eabi-7-2018-q2-update compiler and Make utility to build by project.

Hello,

.axf is a file format used by Keil uVision. The equivalent file for this in GCC is *.out and *.elf.

Best regards,

Hi, I don't think that's true. gcc also also generates .axf file on linux as I have used it to do so for another project. I think .elf format is used in windows based compilers. Anyways, I also could not locate .elf in the repo after build. 

Thanks!

Can you check what is used to generate .axf file in your other project? I have not seen any version of objcopy that supports this file extension, and I have only seen it used with arm toolchains.

The SDK makefiles will only output a *.out file. To get an elf file, you will have to modify makefile.common to generate it.
