function lt_flash_erase

Erase flash area. Flash can only be erased in blocks (usually 4 KiB).

bool lt_flash_erase (
    uint32_t offset,
    size_t length
) 

Parameters:

• offset starting offset to erase (in bytes); must be multiple of the flash chip's block size
• length length of data to erase (in bytes); will be rounded up to block size

Returns:

whether erasing was successful

function lt_flash_erase_block

Erase a single block of flash (usually 4 KiB).

bool lt_flash_erase_block (
    uint32_t offset
) 

Parameters:

• offset offset of the block (in bytes); must be multiple of the flash chip's block size

Returns:

whether erasing was successful

function lt_flash_read

Read data from the flash.

uint32_t lt_flash_read (
    uint32_t offset,
    uint8_t * data,
    size_t length
) 

Parameters:

• offset starting offset (in bytes)
• data pointer to where to store the data
• length length of data to read

Returns:

length of data successfully read (should equal 'length')

function lt_flash_write

Write data to the flash.

uint32_t lt_flash_write (
    uint32_t offset,
    const uint8_t * data,
    size_t length
) 

Parameters:

• offset starting offset (in bytes)
• data pointer to data to write
• length length of data to write

Returns:

length of data successfully written (should equal 'length')
