Hey, I was wondering why exactly Im not meant to use dynamic memory in this?

Say I turned on all (and i mean all) compiler warning and + valgrind gave no errors
would my program be okay in embedded enviroment?

The issue with the heap in embedded systems is that you often only have a very limited amount and accessing it is rather slow sometimes.

Why shouldn't we have dynamic allocated memory with different size ...

I have heard in embedded system, we should use some preallocated fixed-size memory chunks(like buddy memory system?). Could somebody give me a detailed explanation why?
Thanks,
