Dear Bjørn And, one more question is that there --application-version and --sd-req would be saved?

Jake.

Dear Bjørn.

In this case, which address(register) can be used to store user specific data?

Jake

The Customer[0] register (at 0x10001080) is used to store the device type and revision that is checked against the values in the init packet using the --dev-revision and --dev-type options in nrfutil.

If they match, the image is accepted. Otherwise, the image is rejected. To accept all device types and revisions and to disable the check, make sure not to set the UICR value to a specific value, but keep the default value 0xFFFF.

Please refer this page on our Infocenter for more information on the safety checking mechanism.
