Tutorial/example for flash write/read STM32H7

[Riccardo Franceschetto]

How do i find an extensive example for read/write value in flash of STM32H7, for store of data to keep after powerloss or reboot? Thanks

You can find this in the STM32H7 firmware, which not only contains the libraries, but also examples, e.g. FLASH_EraseProgram, which is included there for each NUCLEO, DISCOVERY or EVAL board.

The reference manuals also describe in detail how to write in the flash.

Does it answer your question?

I'm not sure there's "extensive" examples of anything, there are examples demonstrating the functionality of the underlying API functions, and you get to expand and extend those as needed for a specific use-case and application.

There's also an "EEPROM Emulation" library, but honestly I'd avoid that, and understand the flash management at a sector (page) level erase and write.
