About memory use in S32K

juliana_rojas30 — Tue, 15 Sep 2020 13:16:26 GMT

Hello everybody!

I am currently trying to know how much memory of my S32K144 is being used by an application that I made in Simulink.

Looking in the .map file, I find this information:

As I understand, the RAM (m_data) consumption would be of 32 768 B? How is that even possible? Am I reading this the wrong way?

Kind regards,

Juliana

Hello @juliana_rojas30 ,

If you want to get the size of the generated code, inside our toolbox, please go to this location {Toolbox installation}\src\tools\gcc-6.3-arm32-eabi\bin there is an executable called arm-none-eabi-size.exe

If you run this executable passing as argument the generated elf you will see the following output:

C:\.....\>arm-none-eabi-size.exe generated.elf text data bss dec hex filename 46884 1272 6104 54260 d3f4 generated.elf

Hope this helps,

Marius

Hello @mariuslucianand ,

Thanks for your reply. I was trying to look for the direction you said inside the project folder I am working on, but I can't find the folder "tools". There's one called "clock" and another one called "power", but no tools. Actually if I put only the direction directly on the path, I get this:

Should I run any command to generate this folder or something?

Thank you!

Kind regards,

Juliana.

Hello @juliana_rojas30 ,

I think the 'src' is the problem in your path, please open in explorer.

The full path for me is 'C:\AddOnR2019b\Toolboxes\NXP_MBDToolbox_S32K1xx\tools\gcc-6.3-arm32-eabi\bin', but obviously it differs from PC to PC.

Hope this helps,

Marius

hello, when using iMXRT the map file is not getting generated, is there a way to see the ram occupancy (peak ram usage)? i have tried to experiment with the stack profiler from Simulink but i got some errors
