Hello Nordic team,
I'm looking into solution to pass data to my application after a Reset using the RAM of my nrf52840.
Looking at the documentation, this picture troubles me:
I'm interested into the RAM state after a WatchDog reset, and it appears that RAM should be reset on the picture. But just after there is a note telling that the RAM is never reset ?
So I made some tests using a non_init section as described in this bug : https://devzone.nordicsemi.com/f/nordic-q-a/34395/status-of-sram-during-an-over-the-air-update/132658#132658
After a WD reset, the data i wrote in the section are still here.
So what is the case of corrumption the note talks about ? Is data written in a non_init section reliable affter a WD reset ?
Thanks in advance,
Aloïs KYROU
