How to know RAM memory consumption for application on S32K144 EVB

[mrajanna]

Hi,

I have attached .map file for one of the application.

From .map file I extracted below information.

Memory sections	Size in bytes
.data	2436
.text	11320
.rodata	48
.bss	316

I would like to know how much RAM memory will be used when this application run on S32K144 MCU ?

Is there any provision in S32 design studio to monitor amount of RAM used when debugging this application on S32K144 evaluation board ?

Thanks

Mohan

Hi, 

you can enable printing target size by right click on project name -> properties  and check the Print size checkbox 

In build console you can see something like this:

Here is detailed description of each block (text, data, bss...)

Hi Jiri,
Thank you for the information.

From your experience can you please suggest how much of RAM is required in below scenario.
Use case Scenario:
   a. freeRTOS
   b. Load secure key to CSEc + Perform encryption and decryption on plain text using loaded secure key + Prepare for       secure boot.
   c. Run OBD CAN stack
   d. Other hardware initialization if any

Thanks

Hi, 

well - I have no idea how many RAM your project will need - it depends on implementation. But I'm sure that 64kB of RAM on S32K144 is okay for your scenario.

Hi Jiri,

Okay.

If you can share any sample project details like what all components were running on S32K144's 64K SRAM, it will be helpful to me.

Thanks
