Write in ROM memory

[pablourbano]

Hello,

For our application we want to save the serial number in the production line. We want to save it in the ROM area or in a special area will never be deleted.

Do you know if there is a special area to do it?

What do you recommend for that issue?

I was thinking in create a new partition...

Thanks
