Detailed Description

SDMMC ARM9 module.

Function Documentation

nand_GetDiskStatus()

u8 nand_GetDiskStatus

(

void

)

Returns the SDMMC_STATUS bits of the eMMC NAND.

Returns

Returns the SDMMC_STATUS bits or SDMMC_STATUS_NODISK | SDMMC_STATUS_NOINIT on failure.

nand_GetSectors()

u32 nand_GetSectors

(

void

)

Outputs the number of sectors for the eMMC NAND.

Returns

Returns the number of sectors or 0 on failure.

nand_ReadSectors()

bool nand_ReadSectors	(	sec_t	sector,
		sec_t	numSectors,
		void *	buffer
	)

Reads one or more sectors from the eMMC NAND.

Parameters

[in]	sector	The start sector.
[in]	numSectors	The number of sectors to read.
	buffer	The output buffer pointer.

Returns

Returns true on success or false on failure.

nand_ReadSectorsCrypt()

bool nand_ReadSectorsCrypt	(	sec_t	sector,
		sec_t	numSectors,
		void *	buffer
	)

Reads one or more sectors from the eMMC NAND.

Parameters

[in]	sector	The start sector.
[in]	numSectors	The number of sectors to read.
	buffer	The output buffer pointer.

Returns

Returns true on success or false on failure.

nand_SetupCrypt()

bool nand_SetupCrypt

(

void

)

Initialize the aes keys to allow reading encrypted eMMC NAND.

Returns

Returns true on success or false on failure.

nand_Startup()

bool nand_Startup

(

void

)

Initialize the eMMC NAND.

Returns

Returns true on success or false on failure.

nand_WriteProtect()

void nand_WriteProtect

(

bool

protect

)

Enables write protection for eMMC NAND.

Parameters

[in]

protect

Wether write protection is enabled or not (defaults on).

Note

This protection state only affects nand writes performed through file i/o operations. Manually calling functions to write to the nand will still go through

nand_WriteSectors()

bool nand_WriteSectors	(	sec_t	sector,
		sec_t	numSectors,
		const void *	buffer
	)

Writes one or more sectors to the eMMC NAND.

Parameters

[in]	sector	The start sector.
[in]	numSectors	The number of sectors to read.
[in]	buffer	The input buffer pointer.

Returns

Returns true on success or false on failure.

nand_WriteSectorsCrypt()

bool nand_WriteSectorsCrypt	(	sec_t	sector,
		sec_t	numSectors,
		const void *	buffer
	)

Writes one or more sectors to the eMMC NAND.

Parameters

[in]	sector	The start sector.
[in]	numSectors	The number of sectors to read.
[in]	buffer	The input buffer pointer.

Returns

Returns true on success or false on failure.

sdmmc_GetDiskStatus()

u8 sdmmc_GetDiskStatus

(

void

)

Returns the SDMMC_STATUS bits of the SD card.

Returns

Returns the SDMMC_STATUS bits or SDMMC_STATUS_NODISK | SDMMC_STATUS_NOINIT on failure.

sdmmc_GetSectors()

u32 sdmmc_GetSectors

(

void

)

Outputs the number of sectors for the SD card.

Returns

Returns the number of sectors or 0 on failure.
