I am looking at creating a flash sector of "factory information" for our product, which would be unique for each device produced. Is there any tooling around for doing this? What approaches have been successful for you?
There are a few approaches I have considered, including:
- using rustc to generate the data sector as an ELF file, then write to flash with probe-rs
- build custom program that runs on the target, receives data over RTT, and writes the flash
- build custom program to generate the data sector ELF file, then write to flash with probe-rs
