How to realise Real-time detection of access of memory beyond the bounds of an allocation block, instead of period detection in Cortex-M4. Please give me any idea.

Thank you for the reply. That is an good idea. However, the comparator of the DWT uint can only monitor up to 32-byte range of addresses by using DWT_MASK Registers. In my application, the Heap size is at least 50K bytes, so it can't meet all aims.

I'd add a virgin pattern before and after each allocated chunk. A heap scan can check these.

DTW is actually more practical for the stack.
