Options for Sequential Serial numbers

We have managed to program a single serial number into the UICR, using our Development kit and Command line tools.

This was achieved using a batch file that calls this:

nrfjprog -f nrf52 --memwr 0x10001080 --val 0xF1F2F3F4.

This works perfectly but If we continue with this method how could we create an auto sequential number? (Maybe call a stored number from a file and increment by one when finished)

Another idea is to use the Segger Flasher ARM which can be setup to auto increment, but i'm unsure if we can still use the nrfjprog commands to store other details in the UCIR.

Which would be the best way to go?

Hi,

If you are using a single programmer, it should work fine to get/store the incremented number to a file. Just write a script that reads the file, flash the board, and increment the number before storing it back.

Best regards,

We do not have any specific recommendations on this, except from what is described in Production programming and testing documentation.

I would recommend that you contact Segger to get recommendations on which programmer would fit your use-case best.
