Is there any tool to flash serial number in somewhere for nRF51822

[sunnyjet16]

Hi,

When I finish coding, I can generate .HEX file for all products. But for real mass production, I may need to flash a seperate serial number in somewhere for each PCBA after flash firmware. Now, my question:

1. How can I input serial number and flash it into nRF5822?
2. Does it need any tool?

Regards Alex

Hi. In our factory we have a computer with UART that communicates with our PCB. This sets a serial number, we wrote code ourselves for that

A decent production programmer should be able to insert a Serial Number at a specified location in the Hex file

eg www.xeltek.com/.../superpro-xps01-isp-production-workstation (just the first hit on google - no specific experience or recommendation)

Your board manufacturer should be able to help you with this...

You can use our command line tool nrfjprog and a Segger Production Programmer to write the serial number to flash using the --memwr command.

Mobilian has been released a customization feature for production.

You can read/write custom data like MAC, serial number and entire memory while in programming.

Also this new feature enables your own customization process with C# interface.
