CONFIG_HW_STACK_PROTECTION implementation on nrf52840

[Dor Sadeh]

What is the implementation of CONFIG_HW_STACK_PROTECTION on the nrf52840, using Zephyr (ncs 1.9.2)?

How does it differ from using  CONFIG_STACK_SENTINEL?

Hello,

I will look into this.

But are you enabling CONFIG_MPU_STACK_GUARD=y in your project?

Kind Regards,

I do want to enable a stack overflow protection mechanism for my project. Currently there is none.

Before I choose an option I want to understand the pros and cons for each option.

Any news?
