STM32 embedded flash as micro file system

Hi All,

I need to use an stm2f411 embedded flash as little file system. There will be about 20 small files on it. I found the uffs file system which is seems to be good for this.

I found some information in stm32 doc:
- maybe the page size is 512 byte
- there are 16Kb, 64Kb, 128Kb of sectors on it.
- I found HAL_FLASH_Program(), HAL_FLASHEx_Erase() in drivers.

But I need some information about the stm32 flash:
- is it NAND or NOR flash?
- is the page size 512B?
- uffs needs block parameters which is larger than page size. How many is it in stm32?

thx,
Zamek
