Hello, I am studying this which mentions that the MCUboot is placed to immutable section of flash. How is this implemented? I can not see anywhere information about immutable MCUboot partition.

Erasing flash memory problem in nrf52840-dk

Testing DTLS with the echo_client and echo_server samples

#nrf52832
Does zephyr only supports PSK for the DTLS (e.g echo client, lwm2m client). I haven't seen anything about RPK using ECC.

Hi all, I would like to ask you if I can change the lwm2m observer period. There is enough delay (some seconds), after calling lwm2m_engine_set_u8("5/0/3", STATE_IDLE) until the server get informed.

Problem with the NVS filesystem on
#nrf52840
#nvs
Update: if I write and read in a function without some condition (i.e button is pressed) works fine. The problem is when the write/read process is taking place to button_pressed callback function.
