Member Function Documentation

readSector()

virtual bool BlockDeviceInterface::readSector ( uint32_t  sector, uint8_t *  dst  )

pure virtual

Read a 512 byte sector.

Parameters

[in]	sector	Logical sector to be read.
[out]	dst	Pointer to the location that will receive the data.

Returns

true for success or false for failure.

Implemented in SdioCard.

readSectors()

virtual bool BlockDeviceInterface::readSectors ( uint32_t  sector, uint8_t *  dst, size_t  ns  )

pure virtual

Read multiple 512 byte sectors.

Parameters

[in]	sector	Logical sector to be read.
[in]	ns	Number of sectors to be read.
[out]	dst	Pointer to the location that will receive the data.

Returns

true for success or false for failure.

Implemented in SdioCard.

sectorCount()

virtual uint32_t BlockDeviceInterface::sectorCount ( )

pure virtual

Returns

device size in sectors.

Implemented in SdCardInterface, and SdioCard.

syncDevice()

virtual bool BlockDeviceInterface::syncDevice ( )

pure virtual

End multi-sector transfer and go to idle state.

Returns

true for success or false for failure.

Implemented in SdioCard.

writeSector()

virtual bool BlockDeviceInterface::writeSector ( uint32_t  sector, const uint8_t *  src  )

pure virtual

Writes a 512 byte sector.

Parameters
