Field Documentation

NUTDEVICE* _MCIFCB::fcb_fsdev

Attached file system device.

DOSPART _MCIFCB::fcb_part

Partition table entry of the currently mounted partition.

uint32_t _MCIFCB::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.

uint8_t _MCIFCB::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.
