Marko Kiiskila updated MYNEWT-13:
---------------------------------
Description:
STM32F3 flash writes are done 2 bytes at a time. MK64F12 flash alignment is 8.
NFFS should take into account alignment restrictions underlying storage has.
E.g. add alignment requirement in struct hal_flash. Add an HAL flash API call
to query this. NFFS would then use this when writing/reading blocks of data
from flash.
