How terrible is this approach? I'm self taught and was sort of drafted into embedded so I'm unsure of myself here.
Not so terrible, rest assured; don't damage your self-esteem Big Grin | :-D

The biggest issue with dynamic allocation, and where this mantra of "no mallocs" came, is the potential for memory fragmentation. You don't know how well the memory manager behaves and you risk running out of big memory chunks.

However, if you think about it, this is a phenomena specific to multi-tasking, where each task is oblivious of other tasks that may exist in the system. This is not what happens in an embedded system where you have only one "task" (footnote: yes, there are exceptions to this scenario). You certainly have multiple threads but those threads cooperate, not compete for resources.

If you would have an anal boss that wants to enforce the "no malloc" rule, you can allocate all the available memory and run a memory manager inside your app that allocates chunks of this pool. On the outside the system would behave the same way because there is only one task/app. Again, I'm over-simplifying here: there is still a network stack that needs some buffers but you get the gist. In embedded world, quoting Taylor Swift: "This is our place, we make the call".
