Function Documentation

void ctr_fatfs_default_setup	(	ctr_nand_crypto_interface *	ctr_io,
		ctr_nand_crypto_interface *	twl_io,
		ctr_sd_interface *	sd_io
	)

Convenience function to initialize the fatfs system with the io interfaces required to mount CTRNAND, TWLN, TWLP, and SD.

Parameters

[in,out]	ctr_io	A pointer to an initialized CTRNAND io layer.
[in,out]	twl_io	A pointer to an initialized TWL io layer.
[in,out]	sd_io	A pointer to an initialized SD io layer.

Postcondition

The underlying structures in fatfs have been updated (using the custom CTR_SETUP_DISK ioctl) to be able to mount CTRNAND, TWLN, TWLP, and SD.

void ctr_fatfs_disk_initialize	(	ctr_fatfs_disk *	disk,
		void *	io,
		size_t	sector_offset,
		size_t	sectors
	)

Initializes the ctr_fatfs_disk structure.

Parameters

[in]	disk	Pointer to structure to initialize.
[in,out]	io	Pointer to ctr_io_interface to use for the disk being initialized.
[in]	sector_offset	Offset in sectors from the beginning of the given io interface to use as the beginning of the fatfs drive (beginning of FAT partition or MBR with FAT partition)
	sectors	Size in sectors of the FATFS disk/partition.
