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,

AFAIK, there is no limitation based on the number of threads. I was searching for some supporting documents for confirming this, but I couldn't find any from the Arm website.

Kind Regards,
