int bm_storage_erase	(	const struct bm_storage *	storage,
		uint32_t	addr,
		uint32_t	len,
		void *	ctx )

#include <bm_storage.h>

Erase data from storage.

If bm_storage_info::is_erase_before_write is set, the erase address and length must be aligned to the backend's erase unit.

If bm_storage_info::is_erase_before_write is not set, the erase address and length must be aligned to the backend's program unit, or to the backend's wear unit if bm_storage_config::is_wear_aligned is set.

Parameters

[in]	storage	Storage instance to erase data in.
[in]	addr	Offset within the partition where to erase the data.
[in]	len	Length of the data to be erased (in bytes).
[in]	ctx	User-defined context sent to the event handler.

-EFAULT	The storage instance storage is NULL.
-EPERM	The storage instance storage is not initialized.
-EINVAL	The addr or len parameters are unaligned.
-ENOMEM	Out of memory to perform the requested operation.
