Field Documentation

NUTDEVICE * _MMCFCB::fcb_fsdev

Attached file system device.

Referenced by MmCardMount(), MmCardUnmount(), SpiMmcMount(), and SpiMmcUnmount().

DOSPART _MMCFCB::fcb_part

Partition table entry of the currently mounted partition.

Referenced by MmCardBlockRead(), MmCardBlockWrite(), MmCardIOCtl(), MmCardMount(), SpiMmcIOCtl(), and SpiMmcMount().

uint32_t _MMCFCB::fcb_blknum

Next block number to read.

The file system driver will send a NUTBLKDEV_SEEK control command to set this value before calling the read or the write routine.

The number is partition relative.

Referenced by MmCardBlockRead(), MmCardBlockWrite(), and MmCardIOCtl().

uint8_t _MMCFCB::fcb_blkbuf

Internal block buffer.

A file system driver may use this one or optionally provide it's own buffers.

Minimal systems may share their external bus interface with device I/O lines, in which case the buffer must be located in internal memory.

Referenced by MmCardBlockRead(), MmCardBlockWrite(), MmCardIOCtl(), MmCardMount(), SpiMmcBlockRead(), SpiMmcBlockWrite(), SpiMmcIOCtl(), and SpiMmcMount().

uint8_t _MMCFCB::fcb_blkbuf[MMC_BLOCK_SIZE]

Internal block buffer.

A file system driver may use this one or optionally provide it's own buffers.

Minimal systems may share their external bus interface with device I/O lines, in which case the buffer must be located in internal memory.

uint32_t _MMCFCB::fcb_address

Next block number to read.

The file system driver will send a NUTBLKDEV_SEEK control command to set this value before calling the read or the write routine.

The number is partition relative.

Referenced by SpiMmcBlockRead(), SpiMmcBlockWrite(), and SpiMmcIOCtl().
