Hello Hakon,

thanks for the response.

Changing the optimization level only for the application using the .config file in the build folder solves the issue on my end.

Too bad I didn't see the other topic before creating this issue.

Thanks and best regards

Hi,

Unfortunately, the configuration set in your project will be inherited into the tf-m child image.

What is possible is to set the configuration to optimize for size, then re-configure only the application project to use debug optimizations (CONFIG_DEBUG_OPTIMIZATIONS=y) for the specific generated build only:

RE: Using CONFIG_DEBUG_OPTIMIZATIONS with Thingy:91 and Asset Tracker v2

This will leave other images (tf-m/mcuboot) with the original optimization level.

Kind regards,

Håkon
