Micron MT29F serial NAND driver.
This module allows read/write access to Micron MT29F serial NANDs. It is a block device, so it must be accessed using the KBlock interface functions (see kblock.h).
Once you have opened the flash for writing, you may want to use kblock_trim() to avoid overwriting data on other flash banks.
Example usage:
Mt29f chip; mt29f_init(&chip); // enable access only on desired blocks // start block = 50, num blocks = 20 kblock_trim(&chip.blk, 50, 20); // ... // now write to the flash // block number is automatically converted kblock_write(&chip.blk, 0, buf, 0, 128);
