Could you write a small .HEX to a specific configuration location, or into the OTP area?

Is this only way? it is going to tough for non engineers.

I need to give facility to production to program MAC address in each board. Then he needs to modify the text file for each board.

I'm sure there are a bunch of ways to solve this.

Can't you automate text file modification?

Could you provide some user interface or test mode on your device?

Could you connect up the network, and pull a MAC address from a server?

Do you have to use an ST-LINK, could you use some different JTAG/SWD pod, with automation libraries available?

Following is response from st support team and it works...not a guess work like some people do

In Reference manual RM0033, part 2.3.3 Embedded Flash memory, you can find address of OTP (one-time programmable) bytes for user data.

In STM32 ST-Link Utility you can display and modify this part of memory.

Pretty sure this is not fit for an automated environment.

The method of patching or merging the HEX/S19 file is quite common.

Another option would be to program the MAC address as a final step in the product test, with collaboration of the DUT.
