Thanks i see the tab but look like it has no effect
even if change the mcu family and type it always turn back to inital value (.cproject change seam to realy take effect)
and build is always perform usign intial mcu type

the warning seam appropriate 😉
Changing target on existing executable or static library C/C+ + project is highly NOT recommanded, dependencies and options might not be valid anymore. You have to manually reconfigure the project.
