f3s_v2erase()

int f3s_v2erase (f3s_dbase_t *dbase,
                 f3s_access_t *access,
                 uint32_t flags,
                 uint32_t text_offset);

This function begins erasing the flash block containing the text_offset. It can optionally determine if an error has already occurred, or it can just return EOK and let f3s_v2sync() detect any error.

On success, it should return EOK. If an error occurs, it should return one of the following:

EIO

Recoverable I/O error (e.g. failed due to low power or erase failed, but corruption is localized and block will be usable after an erase)

EFAULT

Unrecoverable I/O error (e.g. block no longer usable)

EROFS

Block is write protected

EINVAL

Invalid command error

EBUSY

Flash busy, try again (e.g. erasing same block twice)

ERANGE

Flash memory access out of range (via service->page function)

ENODEV

Flash no longer accessible (e.g. flash removed)

ESHUTDOWN

Critical error; shut down the flash driver.
