LPC55S69 SDK : linker script managed or not ?

EugeneHiihtaja — Fri, 06 Dec 2019 09:53:05 GMT

Hello !

I can see frertos_mpu_ns example is use managed linked script in Properties.

But some how it know about folder linkscripts and take from there all *.ldt files in use and build right memory map.

This connection is not visible any where in project settings. How managed linker script know about some extra rules in other files and if any detail info about it available somewhere ?

Regards,

Eugene

The automatic detection and use of project local .ldt files is an integral part of the managed linker script mechanism. For more details, please see chapter 18, "Memory Configuration and Linker Scripts" in the MCUXpresso IDE v11.0 User Guide. In particular, section 18.3 "How are Managed Linker Scripts Generated?" and section 18.4, "FreeMarker Linker Script Templates".

Hi !

I can see SDK example for freertos_mpu_ns has very good scripts what fit to all needs.

But other part of this project has freertos_mps_s is still use full automatic script.

Do you have scripts for that type of project e.g secure with TZ enabled ?

The generated scripts should work fine with secure and non-secure applications.
