To check the current protection status of connected devices, use the following command:
nrfutil device protection-get --traits jlink
You can specify a particular device using its serial number:
nrfutil device protection-get --serial-number <serial_number>
Note
If you use protection-get commands with a multi-core device, they will only return the status for the application core.
For multi-core devices, you can check the protection status of a specific core using the --core option, like in the following command pattern:
nrfutil device protection-get --core <core_id> --serial-number <serial_number>
--core, the application core is assumed by default.
