f3s_v2lock()

int f3s_v2lock (f3s_dbase_t *dbase,
                f3s_access_t *access,
                uint32_t flags,
                uint32_t text_offset);

This function write-protects the block containing the address text_offset (if supported). If the block is already locked, it does nothing.

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 lock failed, but corruption is localized and block will be usable after an erase).

EFAULT

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

EINVAL

Invalid command error.

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.
