Hi!
Regarding the __initial_sp in the map, studied some articles on the web and even map file: used as STACK for arm_startup_nrf52840.o!
Ok, let us have an example (from map file):
_my_array 0x20002814 Data 125 xxxxx.o(.data) __initial_sp 0x20002891 Data 0 arm_startup_nrf52840.o(STACK)
Just some questions:
- How the STACK/ __initial_sp will be used by arm_startup_nrf52840 in real time?
- What happens if a function in the application, frequently in the real time do memset of _my_array with wrong size, for example 160 bytes (instead of 125)?
This will damage the top of the STACK used by arm_startup_nrf52840.o?
The consequences?
