Hi, I am working on a board running on ARM920T. I am using armboot bootloader and linux-2.4.19 with rmkv patch kernel. The file system is YAFFS. The board is working with Toshiba's Smartmedia NAND flash (512 byte page). Now We have upgraded the flash with STMicro's large page (2048 byte page) NAND Flash. I have successfully tested the flash with a small pattern for erase, write and read operations. Now I am actually working in modifying the nand part in bootloader and kernel, so as to access the flash. After the modification for large page support, I am failing in checking ECC. I am not able to understand the logic implemented in checkng ECC for 2048 byte page. I followed the Linux-2.6 kernel and mtd snapshots from mtd-infradead.org for modifications. I would be very grateful if someone could guide me in doing this work. regards, chandru. -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
