In our project we are using the HID demo project as a baseline for Sw creation.


In it, after compilation, we are getting following memory consumption message after compilation(in MCU expresso).


Memory region         Used Size  Region Size  %age Used

    m_interrupts:         192 B         1 KB     18.75%

  m_flash_config:          16 B         16 B    100.00%

          m_text:      199648 B     251494 B     79.38%

      NVM_region:        8191 B       8191 B    100.00%

        m_data_2:        2240 B        16 KB     13.67%

          m_data:       28744 B        48 KB     58.48%


seems like the Flash memory for application code, is already ~80% consumed? Is it true?

So is it expected that customer to manage their application in remaining 10% or something?(remaining 10% for future use)

And what is design level recommendation from NXP about the maximum consumption for all the memory units, is there a place to see it?
