Hi,<br><br>I am using Micron NAND flash (MT29F1GxxABB) on a custom omap2430 based board, to which I am porting the u-boot (version 1.1.4). I am using the nand legacy driver( drivers/nand_legacy/nand_legacy.c ) for the Micron nand flash. I am able to detect the nand flash, and retrieve the vendor and device ID properly,&nbsp; but read/write operations fail on nand flash.
<br><br>Nand Chip Details:<br>Chip&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; : MT29F1GxxABB<br>Total Size : 128MB<br>Page Size&nbsp; : 2KB<br>OOB Size&nbsp;&nbsp; : 64bytes per page.<br>Block Size : 128KB = 64Pages<br># of Blocks: 1024<br>Bus Width&nbsp; : 16 bit (16x)<br><br>
I have following queries on this:<br><br>1. Does u-boot support large page NAND devices ? and if it does, how to enable it ?<br>2. Does anyone has support for Micron Flash ? Any patches need to be applied ?<br><br>Please help,
