Detailed Description

generic interface for communicate with the flash

Note

struct flash_device * means flash control information

• count: length of the buffer (bytes)
• offset: offset of the write position (bytes, NOT sector(512 bytes))

Field Documentation

close

int(* flash_operations::close) (struct flash_device *)

ioctl

int(* flash_operations::ioctl) (struct flash_device *, unsigned int request,...)

for other instruction sets (barely use)

open

int(* flash_operations::open) (struct flash_device *, const char *name, int flags)

open the flash device

read

ssize_t(* flash_operations::read) (struct flash_device *, void *buffer, size_t count, off_t offset)

read from the flash

write

ssize_t(* flash_operations::write) (struct flash_device *, void *buffer, size_t count, off_t offset)

write to the flash
