#include <zephyr/fs/ext2.h>

Data Fields
uint32_t	block_size
	Requested size of block, in bytes.
uint32_t	fs_size
	Requested size of file system, as a number of blocks.
uint32_t	bytes_per_inode
	Requested amount of memory per inode, in bytes.
uint8_t	uuid [16]
	UUID for the created file system.
uint8_t	volume_name [16]
	Name for the created file system.
bool	set_uuid
	If true then the UUID from UUID is used in the created file system.

Detailed Description

Configuration used to format ext2 file system.

If a field is set to 0 then its default value is used. (For the volume name, the first byte of the array must be 0 to use the default value.)

Field Documentation

block_size

uint32_t ext2_cfg::block_size

Requested size of block, in bytes.

bytes_per_inode

uint32_t ext2_cfg::bytes_per_inode

Requested amount of memory per inode, in bytes.

It is used to calculate the number of inodes in the created file system.

fs_size

uint32_t ext2_cfg::fs_size

Requested size of file system, as a number of blocks.

If 0 then the whole available memory is used.

set_uuid

bool ext2_cfg::set_uuid

If true then the UUID from UUID is used in the created file system.

If false then a version 4 UUID is generated.

uuid

uint8_t ext2_cfg::uuid[16]

UUID for the created file system.

Used only when set_uuid is true.

volume_name

uint8_t ext2_cfg::volume_name[16]

Name for the created file system.

If the first byte is 0 then the default name "ext2" is used.
