Hi

How to set optimization level in ModusToolbox?

I'm also looking for other settings, see the screenshot

The easiest way is to edit the Makefile directly. You can add in the CFLAGS define:

CFLAGS=-Os

This Makefile won't regenerate? So when I add an option it won't disappear?

No. Every project has its own Makefile and can only be edited by the user. The tool will not change it.

You actually need to modify it if you want to use some libraries, like the FreeRTOS, WiFi and so on.
