Date: Fri, 25 Aug 2006 15:11:21 -0700 Mime-Version: 1.0 Content-Type: text/plain; format=flowed List-Id: Linux MTD discussion mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi All, For a newly erased page, the content of both user data and oob are 0xff. If NAND_ECC_SOFT is enabled, the ecc code in the oob, which is 0xff, is not right ecc code. Then if the file system tries to read a newly erased page, it will be problem. Does anyone know how to get around this? Thanks, Han
