Member Function Documentation

isBusy()

virtual bool BlockDeviceInterface::isBusy ( )

pure virtual

Check for BlockDevice busy.

Returns

true if busy else false.

Implemented in SdioCard, and SdCardInterface.

readSector()

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

pure virtual

Read a 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 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 SdioCard, and SdCardInterface.

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 sector.

Parameters

[in]	sector	Logical sector to be written.
[in]	src	Pointer to the location of the data to be written.

Returns

true for success or false for failure.

Implemented in SdioCard.

writeSectors()

virtual bool BlockDeviceInterface::writeSectors ( uint32_t  sector, const uint8_t *  src, size_t  ns  )

pure virtual

Write multiple sectors.

Parameters

[in]	sector	Logical sector to be written.
[in]	ns	Number of sectors to be written.
[in]	src	Pointer to the location of the data to be written.

Returns

true for success or false for failure.

Implemented in SdioCard.
