Hi,

thank you for your comment.
I was able to confirm that I can write to UICR.

The brackets were unnecessary, right.

Thanks.

Yes, you can set it after the code is flashed. You don't need to use brackets around "ID value"

Hi,

Thank you for your reply.

The manufacturing address written to FICR is difficult to manage on the system, so I would like to set an arbitrary address if possible.

As Mr. RayCreemers replied, it may be the easiest way to write an ID in UICR using the command line tool (nrfjprog).
I will try to realize this method but, I have a question.
Can I set the ID value to UICR after source code flashed?

Actually, I have never used nrfjprog before.
So I examined how to use.

When trying to write a value to UICR, is it correct with the following command?

 nrfjprog --memwr 0x10001080 --val "ID value"

I look forward to your answer.

Best Regards,
Wataru

Hi,

You may also have a look at the DEVICEID and DEVICEADDR registers in FICR. Those values are written in production, and are for instance used for providing a random BLE address for the device. Those are well suited if you do not need to choose the specific values yourself.

Plenty of possible solutions. One possible solution would be to store your ID in one of the UICR (User Information Configuration Register). You can do this by using the command line 'nrfjprog' tool. You only have to compile a single image, and configure each board separately...
