hello, (NXP 1768 with RTX) i will use dynamic memory (heap size : 0x5120=20768) in my project. project allocate differente size in function of configuration.
i count the size allocate heap use = (size want + 4 byte pointer)
infocenter.arm.com/.../index.jsp
case 1: at starting, sometimes malloc return null heap use (5246) in this case want alloc less than case 2 allocate 1 struct1 size z and allocate 1 struct2 size y (y<z) struct2 is less bytes than struct1.
case2: but in other configuration can be alloc more than 5246, ex 10 000 allocate 5 x struct1 is ok
in this case 1, i use less byte, but it don't work.
can you explain this?
thanks
