Hi Ruchika, All,

1. The tool, Bohdan pointed can be used for the detailed footprint analyses. For the footprint numbers in releases, I am using a Clang map file with a trivial parser. Clang produces a nice summary table at the end of map file like the one below, unlike GCC. ----------------------------------------------------------------------

2. Profiles are predefined set of configurations for a selected use case, independent from certification. You are right the profile Large uses isolation Level 3 but it's not required.

Hope that helps, Anton

Hi

There is Code size analyze tool - https://git.trustedfirmware.org/TF-M/tf-m-tools.git/tree/docs/code-size-anal...

I believe it is used for code measurements for releases.

Hi,

With every TFM release, I see that there is a memory footprint tablehttps://trustedfirmware-m.readthedocs.io/en/latest/releases/2.0.0.html#reference-memory-footprint which is made available for the AN521 platform.

Are there any scripts available to run on the map file/other binaries to generate this table ? I would like to use the same for our platform and do some analysis.

Further question- Why is there a tie up between the large profile with TFM isolation level 3 ? Is it a certification requirement ?

Regards, Ruchika
