FlashDB support of write grain 64

support of write grain 64

Hi @armink,

Some of the MCU internal Flash from ST has 64bit write grain. Can I easily make changes to FlashDB to support it? Thanks.

You need to confirm whether the Flash supports reverse order writing first.

What is "reverse order writing"? I try to google it but can't find anything relevant. We are targeting STM32WBxx and STM32Lx series MCUs. Thanks.

like this

- write 0x00 to address A: 0x00000010
- read and check address 0x00000010
- write 0x00 to address B: 0x00000000
- read and check address 0x00000000

the address B is less than address A
