Dear Sun,
In reply to your Service Request SR 1-552540237:
Actually, the i.MX21 NAND Flash Controller (NFC) treats a 2Kbyte memory
pages as four 512 byte ones.
Therefore, the data for a 2Kbyte page NAND Flash memory devices are
arranged as follows:
|512byte data|16byte spare|512byte data|16byte spare|512byte data|16byte
spare|512byte data|16byte spare|
not as:
|2K data |64byte spare| ).
So the operation of reading 2k page should be performed 4 times.
Thank you for your interest in Freescale Semiconductor products and for
the opportunity to serve you.
Should you need to contact us with regard to this message, please see
