nand_do_read_ecc

Name

nand_do_read_ecc -- [MTD Interface] Read data with ECC

Synopsis

int nand_do_read_ecc (struct mtd_info * mtd, loff_t from, size_t len, size_t * retlen, u_char * buf, u_char * oob_buf, struct nand_oobinfo * oobsel, int flags);

Arguments

mtd: MTD device structure
from: offset to read from
len: number of bytes to read
retlen: pointer to variable to store the number of read bytes
buf: the databuffer to put data
oob_buf: filesystem supplied oob data buffer
oobsel: oob selection structure
flags: flag to indicate if nand_get_device/nand_release_device should be preformed

and how many corrected error bits are acceptable

bits 0..7 - number of tolerable errors bit 8 - 0 == do not get/release chip, 1 == get/release chip
