Hi.
We are developing a product which has to achieve some safety requirements. The system is quite simple, non-OS, running in a Privileged mode only on a Cortex-M4. I would like to implement a Memory Protection Unit somehow. Could you please give any advice, in which way could be MPU implemented for that kind of system?
If I am correct, one possibility is to protect system from stack overflow. Any other thoughts?
Thank you
There are a number of reasons setting up the MPU with is worthwhile even on a non-RTOS systems (we advise if an MPU is available to always use it).
For example
I have written about this and setting up the MPU at:
