Linker command when building with west

jonasa — Tue, 14 Apr 2026 09:25:27 GMT

Hi,

I build a project for a MCXE31B dev. board using west like this:

west build -b frdmmcxe31b -d build_lwip mcuxsdk\examples\lwip_examples\lwip_ping_enet_qos\bm

A file called

\build_lwip\compile_commands.json

Is generated with all the compile commands which is great.

But I would also like to see the linker command that is executed to build the .elf and .bin file.

Is that command logged in some other file by the build system?

Hello @jonasa ,

Thanks for your post. You can find the relevant information using the command below. See attached picture.

grep -rn "MCXE31B_flash.ld" build.ninja

grep -R "objcopy" build.ninja

Hope it helps.

Celeste
