Hello NXP community,

I am facing some problem, in our project, with the Program flash of the mkw36 microcontroller which is supposed to be 512Ko. However when the program exeeds 50% of the 512ko flash it craches and we are not able do proceed with debug neither to flash it with JLink. To confirm this issue, I moved to the otap example from the SDK and  I declared a big constant buffer so the m_text would bypass the PFlash section. Trying to debug the program, I am facing the same proble. Here after is the result after compilation :


Memory region         Used Size  Region Size  %age Used
    m_interrupts:         192 B        192 B    100.00%

          m_data:       32828 B        48 KB     66.79%
Finished building target: frdmkw36_wireless_examples_bluetooth_otac_att_freertos.axf

Knowing that I am using the SDK version 2.0.0 (issue also appears when using SDK 2.1.0). Can you please help me with this problem.


Best regards,
