class zephyr.FlashArea.FlashArea(id, block_size)

Gets an object for accessing flash memory at partition specified by id and with block size of block_size.

id values are integers correlating to fixed flash partitions defined in the devicetree. A commonly used partition is the designated flash storage area defined as FlashArea.STORAGE if FLASH_AREA_LABEL_EXISTS(storage) returns true at boot. Zephyr devicetree fixed flash partitions are boot_partition, slot0_partition, slot1_partition, and scratch_partition. Because MCUBoot is not enabled by default for MicroPython, these fixed partitions can be accessed by ID integer values 1, 2, 3, and 4, respectively.
