When using the nrfutil device otp-write command, pay attention to the following usage conditions:
-
You must pass
--forceto allow the write. For safety, you must also select the target device explicitly with--serial-numberor--remote-jlink. Using--traitsalone is not allowed. -
The subcommand accepts either a firmware file (
--file) or a single 32-bit word (--addressand--value). These two modes cannot be combined.
