DA14583 for now always allow to bootload your own code over RS-232 that may simply read all flash and send it. Even without this, flash can be just accessed over external pins while CPU is held at reset.

For what i've read already OTP ROM is factory pre-programmed in DA14583. If i read wrong please correct me.

If not - is it possible to get DA14583 chips with unprogrammed OTP so i could program it with with my own bootloader that would decrypt code from flash with our own key?
