flash util

Fields

flash: &'a FlashLock<'a, T, M, FLASH_SIZE>

flash device

offset: u32

offset from the flash start, NOT an absolute address.

Implementations

impl<'a, T: Instance, M: Mode, const FLASH_SIZE: usize> FlashUtil<'a, T, M, FLASH_SIZE>

custom method

pub fn new( flash: &'a FlashLock<'a, T, M, FLASH_SIZE>, offset: u32, erase_size: u32, ) -> Self

create flash util

pub fn new_default(flash: &'a FlashLock<'a, T, M, FLASH_SIZE>) -> Self

create flash util, default offset is 0x100000, default erase_size is 4096

pub async fn try_erase_write(&self, buf: &[u8]) -> FlashResult<()>

try erase and write data
flash memories with lengths multiple of erase_size will be automatically erased. ff data is not empty, at least one flash memory of erase_size block will be erased
