Hi Luca Tollot,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) I would like to know if it's possible to pass a variable in the argument or not.
-- In the IAR demo of SDK library, it's available to calling the malloc function to request an area from the heap, please give a try.

Have a great day,
TIC

I think the size of the heap area in your project is a bit smaller, please re-configure this area, and try again
