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