nand_scan_bbt — [NAND Interface] scan, find, read and maybe create bad block table(s)
int nand_scan_bbt ( | struct mtd_info * mtd, |
struct nand_bbt_descr * bd); |
The function checks, if a bad block table(s) is/are already available. If not it scans the device for manufacturer marked good / bad blocks and writes the bad block table(s) to the selected place.
The bad block table memory is allocated here. It must be freed by calling the nand_free_bbt function.
