Hello everyone, i noted a different mode of handle memory heap region between KDS and MCUxpresso. For example I created two identical project for k64k uC one with KDS and the other with #MCUxpresso leaving the same default heap dimension (eg 0x400 for k64f uC) with booth the ide. At run time when call a dinamic allocation function as malloc and try to allocate a memory area with dimensione greater then heap region, with #KDS the uC run without problem and malloc return a right pointer while with MCUxpresso the function return a null pointer. Can someone explane me what are the difference between the two #heap handling ?
